NEW! CPM S45VN Steel Edge Testing and Steel Talk 

This!!! 62HRC is actually really "tame" compared to what's possible hardness-wise - it's indeed also very important to have an ideal microstructure. 👌🏻

Most important is carbide formation and carbide retention when knife is used. You can have a higher hrc knife that does not retain carbides as well when edge is used as a lower hrc one. Carbides should do the cutting. So it's like cooking.. trying to find that perfect balance. I think the most important step was already done by the community.. and that is.. raise awarness of just how important heat treat is. Understanding how a cheap lower grade steel composition can drastically outperform a very pricey steel just because of heat treat is key. Why spend hundreds of dollars on faulty merchendise.. every knife maker should make it of the utter most importance to get the heat treat right. Because you can make a 1000 knives that kick ass.. or a 1000 knives that are trash.. for basically same money invested. Just dial in on the heat treat is my cryout to manufacturers. Don't waste perfectly good blade steel because of lazyness. Don't fraud your customers by advertising m390 and then have that 300$ m390 outperformed by a 15$ 12c27... it's outrageous. WAKE UP

@@bele28 ABSOLUTELY!! I am so glad to find you guys spreading the word 🤛🏻🤛🏻 Indeed, both at high as well as low HRC hardness you can have good (or bad) carbide stability... It all depends on the overall microstructure.

​@@kknives_switzerland cough cough.. I m in Croatia.. If you get a reheatreat job on maxamet can I send you my native 5 maxamet blade so it gets a piggyback ride to perfection :D

@@bele28 I am still wating for some Maxamet blades to arrive for re heat treating, after those are done, I may have time. But focus is on my own folders for now. Want sum?😄

Vanax 75 is mabye like adamantium

Cpm magna cut🤌 get a very thin grind and make a tough very stainless light saber. It has edge retention similar to 4v/V4E, almost as stainless as lc200n and tougher than cpm cruwear. Go take a look at knife steel nerds, he designed cpm magnacut and has everything you’d ever need to know about it on the site.

Also it’s essentially a very stainless cpm cru wear with better toughness

That's a proprietary name. They've rebranded as magnacut

Which one is stronger vibranium or adamantium?

Justin Haywood Check out Mike Drop podcast as well.....best of the bunch IMO.

@@jfpinkston1 thanks man 👍. Just added it to my list

Ditto!

Justin Haywood I bet you would like project farm. He compares everything

Justin Haywood advanced kb sucks. I like the others listed jus cant listen to his smart mouth

Nah all steels have trade offs from old steels. Every property you change has another property that changes along with the first change. I have a medically alarming knowledge of steels and I can tell you that every steel has a certain property that it’s good at. The only exception to the rule of trade offs is cpm magnacut. It’s like an extremely stainless cpm cru wear with a bit better toughness. Check it out on knife steels nerds it genuinely is a huge change to how we design steels in the future.

@@tristanphillips8937 interesting comment thank you! you and I are totally different in terms of metallurgy or steel knowledge I have very little so quick question why has no one used Magna cut in their knives yet ? can it even be used in knives? does anyone produce and is it coming in the future ?Spyderco seems to use every Steel in the book including cruwear m390 M4 maxamet 20cv and on and on but have not heard anyone speak of Magna cut also second question,..,.the only property I seem to be most interested in lately is Edge retention the way I test sharpness of my knives is by how it pops the hair off my arm if a blade isn't cutting the hair on my arm with ease then it is not sharp to me and I will not use it most of the time. so considering all I'm interested in is Edge retention what is the absolute top Steel for just that property and not just a working edge but an absolute Razor Edge held the longest

@@BuffaloNickel9 yes! Magnacut was specifically designed for knives. However, it’s such a new steel that it hasn’t really been produced yet. I heard that after the melt of steel is atomized it can sometimes sit around for months or even years before it is pressed into a solid ingot. I’m very anxious to see some production knives in magnacut too but sadly it may take some time. As for the second question, ive found my absolute favorite steel for hair whittling sharpness is k390. (You can get a pm2 in k390 on bentoboxshop) I’ve found that almost no stainless steels have that super fine edge holding capability just because they have excess chromium carbide. Magnacut will almost certainly be an exception to that rule though. A Non stainless high alloy steel will probably suit you very well:) I’ve carried my k390 pm2 for about 18 months now without a spot of rust so it isn’t a huge deal to oil it every now and then if you want that super nice edge. The reason it holds an edge like it does is the almost 10% vanadium content and very little chromium or other elements. (Other high alloy non stainless steels like 10v and maxamet may achieve the same properties but k390 has that little bit of extra toughness)

@@tristanphillips8937 hey friend I appreciate the reply in case you didn't know I watched the video from 2 weeks ago at blade show showing Tim Reeve with a prototype sebenza 31 made out of Magna cut blade Steel I watch the video about 30 minutes after I typed my comment to you and couldn't believe it... were you aware of this Chris Reeve prototype in Magnacut made specifically for Tim Reeve to test..? .. perhaps as a future blade Steelo several years from now obviously on the sebenza and inkosi

@@BuffaloNickel9 yes I saw a few prototypes that came out during bladeshow this year and I am dying to get my hands on one. Like I said though they may not go into production for a while. They made a test melt to see the properties of magnacut, which was then divided to a few custom makers for prototypes. I’m sure they’ve started the production process for magnacut but it’ll take a while for those melts to be ready to be sold.

Probably a 25 min job all up. pretty doable, and I tend to fuss a little more

@@CedricAda Awesome, thanks for the response! That's the kind of real world data that is invaluable.

Half x N, you mean.

That really depends on the heat treatment recipe of the s90v in the particular knife being tested. S90v can be poorly heat treated in mass production while still showing 59hrc. It's how the recipe itself does to the composition of the steel inside. When steel is heated all the components of that steel interact at different temperatures for sustained times. If s90v is not done correctly because a manufacturer doesn't want to investigate the best recipe for that composition, it will be abismal. Never trust manufacturers... Most of them do not do that, only few do.

Tactical Center it was a math joke

Wait 45 and 45 is 90 🤯😂

Anthony Vollmer check out my rust test vids, just search ‘cedricada lc200n’ or ‘cedricada rust test’ and theres a bit ive done on it
