How refreshing to see knife content from a knowledgeable designer! I’m so tired of knife salesmen posing as reviewers...The first thing they do is tell you to buy stuff using their hyperlinks. Don’t be that guy
Hyperlinks are a quiet way to help out the content creator without actually giving them money directly and best part is you either choice to use them or you don’t and it’s a policy of RU-vid that the channel must be upfront about them receiving a benefit for using link to purchase .
I really enjoy listening to Mike talk about philosophy and history of blades. He is a wealth of knowledge and something of a hero to me. I have learned so much, and I attribute much of my profiency with a knife in a combat capacity to his teachings. I hope to meet him someday and thank him in person.
I also have an interview with him about what Martial Blade Concepts is. He goes deeper into the philosophy logic behind the system. I presume you are an MBCer?
The wharncliffe is my favorite blade style for several reasons! This video just gave me a better understanding about the design and history! Really enjoyed this interview, thanks!
I'd been interested in buying a Spyderco Yojimbo 2 for the past year or so, but never got around to pulling the trigger on it. Watched this video and read some more about the knife, just ordered the larger Yojumbo a couple hours ago. Can't wait for it to get here!
Wow I have always looked at these type of knifes and it just Amazes me the purpose and functional purpose of this kind of knife . Definitely will pick one up soon !
This video has a guest that knows what they're talking about and an interviewer that lets the guest make their point until a question would actually be beneficial. Sounds obvious but it's not as regular as one would expect. Well done.
Michael Janice is awesome. I have to thank him so much for bringing common sense to the knife world...The Wharncliffe blade is made for slashing not thrusting. No matter what type of knife, thrusting with it runs the risk of the tip breaking. You have to not only understand your tools, but use them in their proper application.
That is completely dependant on the tip geometry, grind angles, and the spine. In a tactical application, thrusting is far more result producing than cutting. Especially in knives less than 4 or so inches.
I'm glad you enjoyed the video! I can't say for certain if you are the first Brazilian subscriber, but you are the first I've known of! Thanks for your support!
The great advantage of the defensive wharncliff is the width of the blade for thrusting. A curved tip is the superior slashing blade yet for over a century it has been shown the thrusts harder to defend against. To be effective the thrust wound must either be very deep or very wide. A 3-4" blade can only go so deep. Using a knife as a slashing cutting attack is a death warrant
Micheal everything your saying makes sense 100 percent. Thats why I own the all black Yojimbo and Yojumbo, and I love both of them so much, they are by far my favorite knives. And even though I own Microteks, Benchmade, Protek and so on, Spyderco is my favorite brand knife. And the Yojumbo and Yojimbo are my favorites. Thanks brother.
@@TheKnifeLifeChannel me to Mike. I carry my Yojumbo 2 every where I go because I'm 54 and not the man I use to be because of a heart condition so thats why I carry the best, Yojumbo 2.
Of ALL the blades I own, Spyderco to Emerson to Benchmade, custom or production, my Yojimbo 2 is the most carried & the most comfortable... It's such a stunner!
So awesome! I love the story of when the light bulb went off with porkman and the old Centofante Wharncliffe and the evil MFer call from Snody. That cracked me up! Great video James and Mike! Can't wait for Blade Camp 2021!
Really enjoyed listening to this. My grandad carried a Wharncliffe blade he picked up in England during WWII officer training. He also gave my uncles and father sheepsfoot knives as children as they were safer in his mind for young farm kids to have. Do you have any recommendations for a regular use knife with a similar profile? I carry a very robust but cheap Ontario knife out on the ranch but would like something a bit more refined to carry away from home.
Justin, I'm glad you enjoyed the video! I'd love to hear more about your grandfather's knife. Blades passed down through the generations usually have a story or two behind them. In regards to knife recommendations: I do use my Yojimbo's for every day use, both in urban and rural environments. Like Mike spoke about, Wharncliffes make surprisingly decent blades. There should be a link to the Yojimbo 2 in the video description. An alternative would be to look at the Custom Jandura's and Jandelica's that are available at 5x5 combat solutions. Those are essentially Enduras and Delicas that have been reground in order to have a wharncliffe profile. You can find those here: 5x5combatsolutions.com/janich-custom Alternatively I'm a bladesmith as well. I recently moved and don't have my shop set up, but I could provide you with a reference or do some custom work for you down the road. Shoot me message at the e-mail under my "About" section and I'll help you out. Hope that helps! Stay safe!
I'm glad you enjoyed the video! I also have another interview with Mike about his Martial Blade Concepts system. I hope to see you around the channel again!
While there are a couple things I prefer to have some belly on my knife for, the wharncliffe similarly works best for me. Which may be the reason why I carry one or two most days...
I was working at a resort in Las Vegas long time ago. Michael Janich was checking out and I was too terrified to ask for an autograph or take a photo. I think he stayed for the shot show. This was long time ago. It was the only resort in Vegas that has no slots or games on property.
Mike would have probably been happy to give you an autograph. He is a pretty cool guy, and I've been lucky to train with him for the last 10 years. If you are in the Vegas area have you connected with Harold Kramer out there? He is our resident instructor in Vegas.
@@TheKnifeLifeChannel I was only in vegas for about 6 months. then I moved back to Hawaii. If I could remember 9/2009 to 3/2010. The resort was called Summer Bay Resorts.
I was always a skeptic of Mikes designs and concepts coming from a different background in the bladed arts.. but, though I don’t agree with some of his concepts in MBC, his logic behind the blade is very solid and his explanation was very articulate. I now own a Yojimbo 2 and a Yojumbo. Looking to purchase a Ronin 2. Thanks for this
I love the design and functionality. Personally, I prefer the TRIAD lock system to Spyderco locks. Since as a first responder, I can attest to the TRIAD's abuse tolerance. Please do some work with Cold Steel someday. I would love to see your blade profile for the Wharncliffe married to a triad lock.
Jormundyr, I'll be sure to check out the TRIAD lock in the next locking video. I am aware of it, but I wanted to make sure I understood it better before I put it into a video. Thanks for your feedback, and thanks for watching!
@@TheKnifeLifeChannel My pleasure. From an engineering background, it is quite ingenuous way to resolve the issues of hard abuse. Short of either using the frame itself (butterfly knives or the Cold Steel's discontinued Triple Action knives). Or resorting to solely designing as a fixed blade. Glad I could be of service to you sir
@@karkkosvolfe the tri ad lock is great. I had to thrust my Coldsteel frenzy into a bipedal hominid and it absolutely demolished them and help up great. Even the tip that hit bone multiple times help up just fine. Was in self defense btw
This man knows knives, and now I know why I love my Wharncliffe blades so much. Working in a warehouse environment I always go back to this blade profile.
Mike has forgotten more about knives than I have ever known. It is always an experience to sit down and talk with him. Wharncliffes surprised me with their versatility and effectiveness in a variety of uses. If you are interested in learning more about the driving force behind Mikes development of the Wharncliffe, check out the second interview with him discussing his combative system, Martial Blade Concepts. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-OQxI_6ngML8.html
I learned this along time ago for me small blades work more efficiently when they are straight and larger weapons like short swords and long swords I prefer a curved blade
I typically prefer my swords straight, or in some cases angled slightly forwards. The Ginunting from the Philippines is one example. Thanks for sharing!
Bringing Mike on board was one of Spyderco's smarter moves. If I remember right, they actually created a position special just for him. Between his writing for the company and the various designs he has created for them, it definitely turned out to be the correct choice.
They are. I have another interview with him about his MBC system which those knives were specifically designed for. Hope to see you around the channel again!
Very good video, very interesting. I never considered a wharncliffe before because it looks strange but now that I see the idea behind it, it makes sense. btw: my first knife I bought, about 20-25 years ago, was a “masters of defense” knife… a “lady hawk” from a corporation with black belt hall of fame graciella casillas-boggs
By destroying my bowie trying to make it more pointy I ended up reaching the wharncliffe design. Learned a lot, had a lot of heartbreak (I hate abusing my knives). It does look quite functional and easy to maintain now. Maybe I'll ask my local bladesmith to forge one properly in the future
@@tobe1207 I'm a knife alchemist lol. Being serious, I don't have the luxury of affording many knives and the bowie I got was lacking in some regards that only by experimenting I noticed (mainly stabbing and chopping power right at the tip).
I carry the Yojimbo two almost daily, depending on where I am. I treat it like my American Express card! Best knife ever created for tactical defense work.
I can see that being the case with some sharpening methods. I typically use a Spyderco Sharpmaker in order to touch up the edges of my knives. I haven't really seen any benefit with the Wharncliffe in that regard personally.
With the thumb placement on the blade, wont you break your thumbs hitting a target? Generally speaking, it takes 3-7 pounds pressure across a joint, and 5-20 pounds across the length a bone to cause a fracture
On a cut, you will be perfectly fine. On a thrust you might jam your thumb. Typically we drop the thumb down out of the way when thrusting. Thanks for commenting and I hope to see you around the channel again!
My EDC is a Boker automatic Kalashnikov Wharncliffe blade. LOVE that blade design. Opened thousands of Amazon boxes! I always looked at it as a utility knife. I had NO IDEA of its tactical uses!! AWESOME video!!!!
I am a wood carver, if I could only have one knife it would be a Wharncliffe. I wish Spyderco would make a knife specific for wood carving. Lucky for me there's Pfeil, Ashly Iles and many others that make gouges, V-Parting tools for me. I also may have an addiction or dependence when it comes to knives. I do know I can only use one at a time, but I need many over time. For my EDC, Spyderco P' kal. Every day is different. So I require a different knife. Some days are a Yojumbo days, or I may have a Reverse day or Ronin 2, Manix. Best days, speed run days. Then there are my Kitchen knives. Then sharpening systems.
If makers actually explained why the knife was built like this guy novice people like myself would be on board for more than just what we think would work well in most circumstances great interview only interview I've found explaining worn-cliff.
Mr. Janich's example relative to the American Tanto is valid only as it pertains to the length of the edge. In fact the very same idea is applicable to the Wharncliffe. In either example, at a certain point you run out of edge. I agree with Mr. Janich that the straight edge is better than the curved edge for slashing, however I want my knife to be effective at penetrating as well as slashing. This is why I think either the Gladius or the American Tanto is superior to the Wharncliffe. Why? Because the Gladius and the American Tanto combine a straight edge with an acute point thereby making the blade equally effective at slashing and penetration.
As soon as I saw the name Wharncliffe, I thought hey sheffield connection as I've been through the area of Wharncliffe near Sheffield and Sheffield was remown as a knife and anything made of steel centre
Yup, Lord Whanrcliffe had close connections with Sheffield and they were the ones that made his designs. If you are interested in some more Sheffield history, you should check out my Bowie Knife video. Sheffield was heavily involved with the Bowie in the 1800s. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE--NsUWXyJN9A.html
How did people not understand this knife. First time I saw it I knew what was up. Ultimate balance of piercing and slashing capability. Defensive blades should be uncoated, shiny and scary to discourage bad guys from making contact.
My guess is that the blade simply looked very different than the conventional wisdom of the time. Mike himself originally thought the small tactical bowie like tips were the way to go until he started playing with wharncliffes. That is what everyone "knew" at the time.
I'm glad you enjoyed the video! I've noticed that soome of Spyderco's knives don't line up exactly centered when closed as well, but I've never had an issue with overall function of their blades.
Mike i absolutely love the Yojimbo and Yojumbo. I carry the Yojumbo every single day for self protection because of the size and shape of the blade. It just seems like such a deadly cutting piece if need to be. Love you brother. And I would love to take classes on how to use a knife for protection.
I can help set you up with an MBC instructor. Check out the instructor locator page on the MBC page, or you can contact me through the e-mail under the "About" tab on my channel. I'll set you up with the closest instructor.
I learned about Spyderco in 1984 at a county fair. I was working a booth in the stuff for sale pavillion. Across the aisle was a guy selling only Spyderco knife sharpeners, I heard and learned his patter and his demos after just a day and was sold. We worked out a trade for goods and I was a Spyderco owner. I've promoted Spyderco sharpeners ever since. It was only in the past few years I learned they made knives too. Great, informative video. Thanks!
Glad you enjoyed the video! Spyderco sharpeners are some of my favorite sharpening tools, but Spyderco has emerged as one of the premier knife companies in the industry.
The Wharncliffe blade is being marketed by Spyderco as the best blade shape for self defense. The straight edge design is effective in self defense, however, many Tanto blades also have a straight edge and the much stronger tip, i.e., Cold Steel Tanto (favorite is the Recon-1 Tanto) allows for more versatility than a Wharncliffe blade in self defense situations. I am amused at the marketing for the Wharncliffe blade in recent years in an attempt to gain popularity and sales. I would also argue that there are also other blade designs that work as well, if not better for self defense.
You are correct in that many blades have a straight edge for the majority of their length and provide the same cutting mechanics in that region. However, the tip of a blade that curves away from the cut diminishes in cutting power. If you are carrying a longer blade such as the Recon-1 with 4 inch that doesn't matter as much, but if you have a 2.5, 3 inch blade you want to cram as much cutting capability as possible into that knife, and the Wharncliffe design is good at that. Wharncliffes have their issues, just like any other blade design. I personally am not a fan of the American Tantos. The strength of the tip is nice, but its performance both in cutting and thrusting is rather lackluster. With that said, my goal is to provide my audience with the best knowledge I can find regarding blades so they can make the best choice for themselves, not to make the choice for them. I hope the video was of some use or interest to you overall.
@@TheKnifeLifeChannel Although everyone has their own personal opinion, I am really amazed by your reply regarding American Tantos. Your knowledge seems lackluster in some respects. The American Tanto made popular by Cold Steel has proven to me that it is a great slicer/cutter and piercer. I personally am not a fan of the Wharncliffe but I would only consider a Wharncliffe if I wanted to carry a 3 inch or smaller knife for strictly edc tasks. "The Wharncliffe blade evolving to the combative knife of today". ???????
I was surprised that Mike didn't bring along one of his Be-Wharneds as well. I suspect that he was focusing on the highlights of the Wharncliffe evolution, and the Be-Wharned is somewhat of just a transition blade between the first and second Yojimbos. But I don't have a good answer for you on that one.
The kiridashi is very similar, but not quite the same. When you grip a kiridashi, the edge angles back to meet the spine, rather than the spine dropping down to meet the point. In a combative scenario the Wharncliffe lines the blade up with the knuckles for more aggressive cutting, and allows the angle of the back of the blade to create the wedging action Mike was talking about during a thrust. But when used as a utility blade there is little functional difference between the two.
Agreed. The kiridashi being a cultural knife, like the seax, will not receive the same accolades though without a face 3:22-3:45 says it all. 5:00-5:30 The kiridashi too was a multiuse pocket knife made for utilitarian purposes and used by everyone from trades carpenters to school children. I mean design wise a knife is a knife, just how a hammer is a hammer, but hey a weapon is a weapon when readily available. The shape of the kiridashi is not exactly definitive from what I've been able to discern due to the long cultural roots and artistic aesthetic therein, save for not being double edged. That is potentially the big difference not discussed; no double bevel, right? But sharp AF, and easy to sharpen thusly. It's an unfortunate coincidence that 'yojimbo' being a Japanese term is being attributed to a Wharncliffe knife inspired shape when the epiphany of the blade concept is, according to the guest speaker, as much a Japanese invention as is it a English Aristocrat one or even a Nordic with the seax. The concept of Japanese steel still is able to transcend the modern consciousness and deserves more credit in my opinion. Speaking of, the opinion of technicality of Wharncliffe and his contribution could possibly be that Wharncliffe made it a foldable pocket knife, rather than a fix blade. What do you think Gieszkanne?
wow as knife collector... i really would like to meet michael janich... was impressed with the history of the wharncliffe style... i'm so honored to have a yojimbo 2 with the michael janich initial on the blade...
Glad you enjoyed the video! I've carried Yojimbos for a while now myself, and I think you will be happy with your new blade. I have another interview up with Mike about Martial Blade Concepts as well if you are interested in seeing more of his content.
Sometimes its good to have a duplicate. I have a similar situation with the Euroedge knives. I got my hands on two of them before they became impossible to find.
@@TheKnifeLifeChannel I just bought two Ronin 2's and two black Yojimbo 2's too 2222222222222222222222222222222222222222222222222222222222222222222222²2222222222
Outstanding and very informative video. I have one of the Snody Benchmade warncliffs. Only complaint is it’s a tip down only knife. Also have the Ronin 2 and am waiting on the Yojumbo. Thank you for this video. New subscriber here.
I wasn't aware of the Benchmade wharncliffs before I did this video, and I've been looking around to find one for the collection. I believe I have a link in the description below to where there are Yojumbos in stock. I haven't checked their price in a while, but last I looked it wasn't bad. I'm glad you enjoyed the video! If you haven't already, there is also an interview with Mike up about MBC, the system that really drove the development of the Yojimbo line of knives!
Hmmm... That's a tough one. I would say keep an eye out on E-Bay and on auction sites. You could also ask around on some of the Facebook BST groups. But I haven't seen them transferring around.
Never compare the cutting performance of a hawkwill Spyderco Civilian or Matriarch (Cold Steel Black Talon) serrated blade with a straight Yojimbo blade. Sure, for stabbing the firsts are not ideal.
Dear Sir, your logic ALMOST makes sense, UNTIL one recalls the REAL tactical knives that emerged in the late 19th and early 20th century during close-quarters trench warfare of WW1. I mean, of course the famous Fairbairn dagger, and the earlier Kriegsmarine and officer’s daggers and other trench-knife analogues in the armies around the world. Those, of course, were the close relatives of a bayonet. About two hundred years ago, armies discovered that cutting ability was not essential in a tactical battle knife, but in the 20th century such knives were given back some cutting edge to add some general utility to the otherwise purely tactical knife. The earlier progenitors of tactical knives were not meant to cut either- think of the trefoil bayonets of WW1, the earlier small-swords, and the still earlier stilettos. British army coined a phase "- to give a point", which just about sums-up proper tactical use of edged weapons! There was even a famous jail lore in the early 20th century (encountered in some memoirs), that a person carrying a large cobbler awl was considered more dangerous than the one who carried a knife! Only in the movies like "Rambo", flailing arms for the purpose of cutting appears to work, but only because it is cinematic. I think that real life encounters in military tactical context involve much more stabbing than cutting. That is why those who served in any armed forces would have probably been introduced to the basics of defense from stabbing and the basics of counter-stabbing. We should also not forget that, most of the year, people normally wear clothes., unless they are at a beach. Have you tried cutting with a knife through a wool coat or a down jacket, or even a thick sweater?? - Good luck with that! - That is why, when you look at a proper folding tactical knife (This is an oxymoron to start with, but let's for a moment suspend our disbelief) -like Boker Tirpitz, for example, you notice that the blade is a typical bayonet blade with centered strong point and false edge for good and easy penetration, while its cutting edge is there merely for increased versatility of the knife, because most people will use the knife for other tasks rather than stabbing... Cheers!
Yory, good to see you on another one of my videos! As I mentioned in the combative knife video, the Kriegsmarine and officer's daggers where parts of the dress uniform for the commissioned officers. Combative knife training also wasn't really part of a soldier's training during WW1. Any CCW combat was predominately boxing or other empty handed fighting, combined with bayonet drill for basic infantry or fencing for officers, if they were even issued a sword. Typical animal brain instinct in these situations is stick the bad guy until he stops moving or keep hitting him until the same thing happens. Thus the trench knife, which is essentially a sharpened awl with brass knuckles, was born more out of what people were doing, rather than any logical design. The Fairbairn dagger is actually a child of WW2 and not a trench blade. It is a thrusting blade and was used to attack the targets of the famed Fairbairn's time table of death; a table that is wildly inaccurate under professional medical scrutiny. I would refer you to the book, Contemporary Knife Targeting by Christopher Grosz, or talk to any medical professionals you may know. Much of the tactics of the WW2 time were based off of confidence. Tell a brand new OSS spy to palm a cracker box and crack a Nazi upside the head with it and you are 100% good to go. Or stick a Nazi in the neck and 5 seconds later he's done. It doesn't really work that way of course; but it was how they got scared kids the courage quickly to go do stupid stuff. Bayonets! I have a video I'm working on right now on this topic, so check it out later! The Trefoil bayonets you mentioned were remnants of the line-of-battle warfare, meant to turn a musket into a spear, so that formations of infantry could ward off cavalry, or intimidate other units in a charge. Actually bayonet clashes were much more rare than many people believe; as such there was largely little emphasis on bayonet fighting. "Essentially stick them with the pointy end" was considered good enough. The US army didn't even have a bayonet system until Capt. McClellan translated the French system by Gomard during the Crimean war. More modern bayonet systems (WW2 and later) make use of edged bayonets to cripple an enemy's advanced targets with cuts. Puncturing weapons will do the job eventually, but cutting is generally preferred when possible. Going back to the days of armored combat, you will notice that when fighting unarmored combats, cuts are generally the more preferred strikes with swords and sometimes even spears. When fighting armor, only thrusts were used in order to drive through weak points only covered by padding or maille. Rapiers and smallswords evolved from this as dueling weapons, as the thrust was much quicker, and often the idea was to simply draw blood rather than to kill. The military weapon evolved into the sidesword, and then the saber: the premier edged tactical weapon of the 19th and 20th century; a primarily cutting weapon! Now of course these are swords, but you should also look at some of the other prominent blades of the 19th and 20th centuries, such as the bowie knife. the Bowie is a hideous piece of weaponry, and was so feared and misused it was outlawed in the United States for a number of years. A quick look at its history, and there is a good chance that blade has left more dead bodies behind than any trench knife or Kreigsmarine dagger. In regards to cutting through clothes, its very doable. Look up various knife attacks, and do some quantitative cutting with a sharp blade on your own, and you can verify this for yourself. Difficult materials, such as really thick winter clothing can be thrust through then cut out of, or pressure cut through with ease. Again, verify for yourself. And even if you only care about stabbing, then I refer you to 28:05 of the video, discussing the puncture mechanics of a Wharncliffe, and what Mike determined from his tests. What he describes there makes perfect sense to me from a quick review of classical physics. One of the things that I will be doing on this channel this year is working on the mathematics and physics of cutting, and trying to develop meaningful cutting tests. I know that you aren't a believer in Mike, and that's fine. So how how about we work through what really works, scientifically? Let me know what you are interested in seeing in that aspect, and I'll see what I can come up with. Thanks for your support!
@@TheKnifeLifeChannel Hi there, when I wrote what I wrote above I was a little bit peeved (I also posted the same writeup to several channels), as I just discovered that for some curious reason, Yojimbo that was previously fading out of public consciousness, was somehow resurfacing again on people's radar. I actually do not have much against this knife per se, expect that I find its tactical pretention misleading - and this kind of spoils the knife for me. Cheers!
@@jawsfederation To each their own, of course! As you probably already know, balisongs and other 'fidgety tools" are just perfect for those men who absolutely HAVE TO occupy their hands when not masturbating, so needless to say that a blade shape in a balisong matters very little...
@@jawsfederation I certainly wouldn't call it the ultimate knife, but I wouldn't mind having one. I enjoy balisongs immensely, and I obviously enjoy wharncliffes.
Been carrying a yojumbo as a trade worker for about 9 months, the thing is an absolute laser when it comes to slicing anything. Really appreciate Mr. Janich's design every time i use it. Cool vid, liked and subscribed.
Any sailor coming aboard a HMS ship going back hundreds of years would be inspected for pocket knives. If it had a normal point , it's tip was broken off so the knife was less efficient to use in a mutiny. Least thats what I read. Trust the British to know what their people are like.
The idea of a tactical wharncliff has existed for a while, but Mike was the one who really brought it into the spotlight. I'm not aware of any early interest in wharncliffes from Fred. I'll see about asking Fred the next time I get the chance.
Someone needs to tell Mr. Janich that a guy named Jason Hanson is shilling a self-defense knife called the Berzerker Blade that looks suspiciously like Mr. Janich's design.
Michael Janich is awesome he always comes across as an incredibly intelligent man. He looks like a geography teacher. I wonder how many people have underestimated him and regretted it ?
Used to carry a sprint run Yojimbo 2. Recently a local shop had a Ronin 2 in the case and well it had to go home with me. Fantastic design, very thoughtful and functional.
I'm glad you enjoyed the video and I hope to see you around the channel again! I have another interview with Mike about his MBC system and I literally just released a video on the KA-BAR knife from WW2!
Hawkbills work even better for pure cutting power for the size, but you loose a lot of the utility in fighting and general work. And with belly you get more edge for the length. And with sword a curved sword acts like a circular saw when your swinging
Hawkbills are even more aggressive cutters, but they do have their disadvantages like you mentioned. Adding belly to a blade has its own theory behind it as well. I talk about a number of these blades in another one of my videos, "How to Select a Self Defense Knife." ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-qf7sYcQo4q4.html Check it out if you get a chance!
@@TheKnifeLifeChannel ooh I wil thank you , I already know what I like but I love learning more. I was just pointing out the other blade shapes for other viewers
OUTSTANDING Topnotch vid IMO... Really curious to know if there's an optimal tip angle deg'\ for penetration w/ the ballistic pendulum knife test and does the knives used/in-question perform the same while inverted. Leading me to also think if the pendulum radius matters to a measurable amount w/o changing mass, I personally believe it would due to "lever". We all know what happens regardless of radi when mass is added. So beveling or even sharpening the Wharn ramp on the front above the ver tip would be chasing your tail ? Why does that sound wrong other than hydra-turbulence retarding momentum.
Thank-you! One of the things I plan to get into on this channel is cutting mechanics. I'm beginning to start the background research, reaching out to my mechanical engineering and physics friends, and talking with people like Mike. I'm hoping to develop replicable test methods that provide useful information. Where I'm going with this is that I don't have answer regarding for an optimal tip angle for penetration, but I'm going to try to find out for you down the road! In regards to changing the length of the pendulum, you would certainly notice a difference with a significant enough increase or decrease in length. Increasing the length of the pendulum will increase the observed velocity at the lowest point of travel, and vice versa. Looking at the basic equation for kinetic energy KE=1/2mv^2, it can be determined that a change in velocity will greatly influence the energy at the time of impact, and therefor the performance of the blades. If you make the pendulum long enough, every knife would either achieve maximum penetration or fail. As for beveling the back of a wharncliffe, I don't have a good answer for you. That's a good question, and I'll see about getting back to you on it.
In Japanese "long" blades the curve make sense because it in effect enhances the draw cut even if your motion is not drawing back. In other words with a strait edge long blade you can chop but to cut you have to either push or pull (draw) to slide the edge and cut with the built in curve of the Katana even with a chopping motion you have a built in draw or pulling of the blade which make it cut more efficiently, but Mr. Janich is absolutely right in that a very short blade the curvature stops being an asset and a straight blade is more effective. It is hard to verbalize and if you see the effect of a long curved vs long straight blade it becomes obvious, just as it is obvious the other way around with short blades because the draw or curvature comes from your arm's motion.
Mike actually theorizes the other way around. He conceives of a blade as a lever, and a poor one at that. The further down the blade from your hand you get, the less pressure you can apply to the cut. A straight edged blade with cut with decreasing pressure. You can compensate the loss of pressure by curving the blade forwards, and this is where blade designs such as the Filipino ginunting come from. Ginuntings are about the most aggressive cutting edges I've encountered in long blades. According to Mike, curved blades have a tendency to reduce pressure the further down the blade. You'll note that curved blades such as the saber, or the tachi tend to arise when cavalry became the preeminent force in a region. Theoretically a curved blade is preferred from horse back because of that release. Cutting something as it goes by at 25 MPH means that applying pressure to the cut really isn't an issue, but losing your sword is. Now with all that said, I've heard arguments the other way like you stated. My thought is that no one has really done much in the way of actual scientific experimentation on the topic. I'm currently doing my research and looking at how to design an experiment. Keep an eye out for that in future videos. Stay safe, and I hope to see you around the channel more!
@@TheKnifeLifeChannel yes I saw and heard that and I agree especially in regards to a short blade that already has the arching motion of the arm of the practitioner. In addition he mentions delivering 100% energy also true and good but the length of the katana diminishes the arch and the curvature in a small way but it still dos mimic's the pull cut. If you take a dinner plate and you place it on your thigh vs a flat straight ruler you will see that the amount of contact with the thigh is smaller with the round dinner plate if that were the curved blade and it were entering the skin and muscle of the thigh it would progress and take more real estate as it deepens. I saw this explained in a visual format on a documentary many years ago it is hard to verbalize. but 10 lbs of pressure on a large flat thing vs a pin would have different penetrations. All the energy is applied to a smaller area and progresses as it continues on it's path. The length of the blade is the issue that makes a straight blade better because of the curvature of the arm motion. but with a longer unit the arms and a long blade it changes thing. There are other issues including balance and help in keeping the blade aliened as it make the cut. I found this short on youtube. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-WhOs-hsjh9c.html
I haven't met Snody yet, but I've hear a lot of good things about him and I've been impressed by his work. I'd like to get him on the channel some time. I'm glad you enjoyed the video!
I'm glad you found it useful! Yojimbos aren't cheap, but they are excellent pocket knives. I have a link in the description below to a place that has a decent price when you are ready to get one.
Thanks for the video nice to see Michael as I have been following many of his articles in different magazines for years including my favorite knife magazine which unfortunately is no longer printed COMBAT KNIVES magazine.. I really enjoyed Michael's articles over the years my other favorite author of various articles in nice magazines is..JERRY VAN COOK.. started getting into reading these articles back in 1991...
I don’t buy it. In actual practice, it’s just not as useful of a design. If you are limited to a 3” blade, then maybe... Why loose the ability to stab deeply to reach vital organs? I have investigated stabbing with short blades and slashing knife attacks and victims say they just thought they were being punched. In the slashing attacks the victims sometimes fought for 30 minutes to an hour before bleeding out.
I would say go check out my interview with Mike about Martial Blade Concepts. The issue you addressed isn't limited to just short blades. Mike originally thought that thrusts to the body were the way to go as well. That changed when he was called in as a witness on a case where an individual was stabbed about 20 times with a 12 inch chefs knife during a 5-10 minute fight until the individual bleed out. Multiple of those injuries were fatal. Because of that, MBC shifts to cuts on targets such as the quadricep and bicep, which immediately disable those limbs and provide instant stopping power. The wharncliffe is ideal for that, especially in a 3" blade which many jurisdictions do limit you to. I would say watch that interview; I'll let Mike speak for himself.
