@E.L.RipleyAtNostromo 9 месяцев назад

I did this the other day with all 22 of my ZT’s, and 4 of them ended up failing. As did an MSI and two XM-18’s. And it doesn’t bother me at all. I really think it’s a non issue. There is no scenario I can imagine where if you’re pushing down on the edge and cutting, applying upward pressure to the blade, that the back of the spine is going to be simultaneously struck harder with more downward pressure and close on your hand, especially if you’re holding the lockbar. I don’t know why this has taken on so much traction, with a guy online the other day calling the MSI “crap” because the spine whack closed it. To me, it’s like complaining that if you flip a car over onto its roof that the passenger compartment might get mashed. Ok, sure, but what’s your point? I don’t even bother testing them this way anymore, but thanks for doing it for us! 👍

@anthonyberardi8904 9 месяцев назад

Right, like he said in a real-life situation the lock won’t be “shocked” that hard, and if your hand is on the lockbar and under the flipper tab it wouldnt close anyway

@jason11286 9 месяцев назад

100% this. I also don't know why this is such a thing now. I've never spine whacked any of my knives because that can't and won't happen while I use them. I've never had any lock fail during any kind of use, be it liner, frame, or button lock. I wish this fad would go away already.

@P.W.R. 9 месяцев назад

@@jason11286 "but its muh lock strength," they say. If you want to bang on your knives like a neanderthal, be my guest. I get the idea behind it, but it just seems dumb since you are NOT supposed to use a knife like that. Impacts are always possible while using a knife and it is up to you to use a cutting tool carefully and responsibly. I will NEVER put myself in a situation where I would cut myself or create an impact. Accidents happen of course, but I am very mindful while using a knife. I don't want an accident so the likelihood of one happening is very, very low. However still possible, but very low. So low that I do not need every knife to have triad levels of lock up just to cut something. People seem to forget that knives need to be treated like loaded guns. Cut away from yourself (barrel pointed down and away from others), don't put downward pressure on the spine (don't look down the barrel), and keep your fingers out of the cutting path (finger off trigger and safety on). Not sure if that analogy works. My brain is weird. I don't want a lock to fail so do not get me wrong. Passing a brute force test is cool I suppose, but in my opinion it feels pointless. Knives don't cut by hitting repeatedly with the dull spine of the blade. Eh, I don't know.🤷‍♂

@brunorojas3992 4 месяца назад

A zip tie closed tight you use the knife to cut but this zip tie is heavy duty so it doesnt cut as you remove the blade for the incision area the spine hits the upper part of the ziptie and thats cause the knife to fail. Happened on a sog keyknife lockback.

@E.L.RipleyAtNostromo 4 месяца назад

@@brunorojas3992 I can’t picture it, sorry. Not doubting your version, but can’t see the back of the blade hitting the upper part of anything. But I slip the blade tip up under zip ties regardless and just lift up popping them off, so, again, all stress is reinforcing the lock anyway.

@gologulug1295 9 месяцев назад

This test isn't realistic and the explanation is incomplete. When whacking like this, you create a shock on the materials, creating a resonance, making the locking surfaces jump on each other. That jumping can move the parts away from their ideal locking position. Especially on the frame locks, the hand will not only tighten the position of the lock-bar, but also dampen the resonance. For the other locks, the risks remain. Do the tests again with a regular grip and a secure glove and whack the blades, not the other way around!

Holt knives are also known for failing the spine whack test very easily. After watching this video I tested my Holt Specter and indeed it failed the spine whack, even when just hitting the spine on my knee. Someone at Blade Show went to the Holt booth after buying a Specter having this issue, but was told "That's normal for us.". And the knives with this issue which he returned were re-sold the same day to other customers. So apparently some companies don't care about their knives failing this test easily.

@jonathanscott5932 6 месяцев назад

My question here would be a should it fail? I understand the force of grip will make the lock almost completely fail safe but should the makers be relying on this fact or should the lock work without? A slip joint with a pin relays on pressure a frame lock shouldn’t.

@scod3908 2 месяца назад

Have a look on youtube, there are several videos of frame locks failing. Do not assume, test your knives to see if they are safe.

@theamericancristero7390 5 дней назад

An impact will defeat your grip. Think of it like a person weaker than you trying to push a knife into you as you ala Hollywood hold their wrist; Then they use their left hand to smack the back of their right hand, and suddenly it starts to break your guard. Hand pressure maintaining a frame lock is not consistent with how grip strength actually works. We're talking about sudden impact, whether the knife slips or you're defending yourself, the tip impacting a hard object is not weight hung like in a cold steel video, it is a sudden impact.

@ericblase4873 9 месяцев назад

My only knives I could get to fail were both Civivi’s, Hypersonic and Voltaic. Both failures easily repeatable but also both newer knives for me so maybe that break in period or cleaning the lock surfaces will fix it.

@scod3908 2 месяца назад

You are FAR too forgiving on the manufacturers. An unreliable lock is a safety issue and is totally unacceptable, especially on a high end blade which will be razor sharp and even falling under gravity will cause a deep cut. Every one of those locks that fails from a light tap is faulty and should be recalled.

@plausible.deaniability 9 месяцев назад

I stay getting up-and-down/front-to-back lock-rock/blade-play on my knifes... specifically liner locks and button locks. The only lock that has failed on me has been Benchmade's Axis Lock on a G10 bugout when the springs snapped. Also, do all crossbar locks have blade-play/lock-rock?

People rushing to say the spine whack test is dumb, don’t use their knives in a work environment. Like say a skid full of bricks your cutting staps off of and in a hurry, your knife is going to get spine whacked, on the farm cutting open feed or untangling who knows what, the back of your knife is going to hit a fence post or gate post. I had the Towser K bit me while working on my bench and after a cut I moved my hand and hit my gun powder dispenser and it failed. If I’m not cutting in the triangle of death or towards myself, I shouldn’t have to worry about getting cut by my knife. I know most of you want to validate your $500 purchase to sleep better at night but guess what they just keep screwing you over because they know you care more about fitting in than actually using their knives. Hinderer has 20yrs of quality issues yet people just have to have them, they suck at every thing. They’re soft, they come dull, the lock fails, parts just fall out, the grinds are rarely right and their CS is terrible. Same goes for Microtech.

@bon3y4rd 9 месяцев назад

I just don't think a spine whack test is a good test. Pocket folding knives aren't designed to be hammers. Testing them as a hammer isn't a valid test. The best test would be whether the lock fails while using it for what it's built for. It's like testing a flat head screwdriver as a chisel or a pry bar. It's going to fail at some point because it's a screwdriver, not a pry bar or a chisel. Great video though!

@kingtaj 8 месяцев назад

Can someone explain to me why this matters in the least? If a knife fails this spine whack test, what is the real world impact? What usages does it affect?

@BB-tv3bw 9 месяцев назад

I'm surprised more knives don't fail this test. By whacking the spine, you're turning the knife into a Newton's Cradle and any lock that lacks enough inherent friction in it's design and lockup to resist the transfer of kinetic energy will want to thrust the lock mechanism back the way it came. "Failing" this test doesn't in itself make a knife worry me anymore than a handle failing a cut test because it's simply not how they are designed to operate. However, button locks in general just don't have enough contact in their mechanisms to interest me. All that said, what would really interest me is whether the same whacking test done on the SHARPENED edge would create enough dwell time of the lock mechanism loosening to fold the blade shut after you lift it off the struck surface immediately(or pass through immediately as in chopping a branch in one stroke). A chopping test if you will, more in line with actual use cases. Guessing you would find the same knives would fail. Chop with fixies only is my 2 cents, regardless of which edge you choose.

@gologulug1295 9 месяцев назад

Exactly! Newton's Cradle is a good analogy :) Whacking like this creates a shock on the materials, resulting in resonance, making the locking surfaces hop on each other. So the parts can move out of their ideal locking position. On the frame locks, the hand would tighten the lock-position (as Jared already mentioned). On all knife-types the resonance might be dampened significantly just by holding the knife naturally. On button locks, exactly this test is not only ratttling the buttons free but also the swinging may prevent the spring to do it's repositioning work (kinda special scenario imho). All in all, It would make more sense to redo the tests on the failing knives with a regular grip (using a secure glove) and whack the blades with wood, not vice versa! BE FAIR!!!

@BB-tv3bw 9 месяцев назад

Yeah, that would be interesting! Damping would have a positive effect on many designs. Guys just need to be careful. Jared is brave doing this without kevlar gloves or something even with his careful grip. CBR's mishap with the MSI, if you caught that, still makes me wince!@@gologulug1295

@scod3908 2 месяца назад

You have clearly never been cutting a hose in an engine bay, had the spine hit something and have razor sharp steel swing into all 4 fingers ruining your day There's no excuse for a failing lock. You can't slam budget makers for a bad grind and then forgive premium products for a design/manufacturing failure that is a considerable safety issue Another situation that can cause a similar failure is the blade getting stuck/wedged, and a repeated back and forth motion on the blade with considerable force trying to get it unstuck Again, there's no excuse for a failing lock on an expensive boutique knife

@toddcarr. 9 месяцев назад

All it takes is to have a knife fail on you once to make you test every knife you have. Happened to me once and it got me bad enough that it changed my view on what a locking knife is supposed to be. It happened during a back strike when i pulled the knife out of a cut quickly and struck the spine of the knife. A touch of sanding with a diamond plate to the lock bar face was enough to correct the problem (only a tiny amount was needed). Afterwards i checked every knife i own to ensure a solid lock up. No reason whatsoever that a knife made today should fail this simple test. Its either a design problem or a manufacturing problem 100% especially after a proper break in period. Thanks for the great vid Jerad and keep making sharp things fun and enjoyable.

@brunorojas3992 4 месяца назад

I have a frame lock. Okc shrika. You just gotta simply look at the spine and it ublocks. The liner doesnt slip under the blade. It kisses it so it just doesnt engage. Eventually ill look up how to fix it.

@informedcitizen8687 9 месяцев назад

Honestly,I dont care if my knife fails a spine whack. I dont use a folder in a manner that would exert force on the spine, and definitely not with a hammering action. If I need to use a knife like that, I'd choose a fixed blade. But i can see how some would be concerned .

@NeevesKnives 9 месяцев назад

Yeah I think most people won't be effected, it's more for the guys that are serious users, carry on the job, etc

Thanks for making this video. Before buying a knife I want to have as much information on quality and durability as possible

@robertbarnum7541 9 месяцев назад

Yes. I think that is the essential undercurrent in this new (thank you GBall) facet of digging into "quality". These exquisite steels and knife builders raise the bar on all aspects of these creations. It's not criticism to be mean, it's the striving for excellence at all levels of price.

@@megacab clean/lubed, worn in vs brand new, density of material being knocked, manufacturing differences, etc Lots of knife makers have also silently fixed this safety issue over the last year as it's become apparent the issue is rife in the industry.

0:50 Friction, as we define it, is not a function of time. I think what you are describing is a different phenomenon or a combination of phenomena related to bonds. I don't think those are at play here however. I believe the reason for the lock failing has more to do with the contact between the locking parts being disrupted because of the sudden jolt due to the spine being whacked. At that point the friction changing from static to kinetic might also play a part.

@CuttingBoardRx 9 месяцев назад

Since you getting all technical, what Jared calls friction is actually friction. I called it a static lockup in one of my vids, but explaining the Young’s modulus of elasticity, More’s machine taper, and bearing pressures due to contact deformation is not only difficult, it would also be boring to 99% of knife users.What you called a jolt and Jared called time to form friction are basically substitutes for the term Impulse. What’s important is that finally one of the biggest knife channels is holding the industry to task and he’s going to get them to listen way before I could with my 4K subs…

@robertbarnum7541 9 месяцев назад

@@CuttingBoardRx Would it be fair to say that the spine tap vibration (micro-separations at the lock contact surfaces) plus less than optimal contact (angle, area, machine finish, etc) at the point of lock up is the root cause? Can you simplify your analysis to a layman's understanding? And thanks for chiming in. I love the informative cross-talk in this community.

@NeevesKnives 8 месяцев назад

Turning with knife in hand and it hitting something, knife getting stuck going through something dense and needing to be pulled out, pressure on the spine of blade, small taps to cut through something like cordage or wood, fighting with the only option you have etc...

@OGBladeReviews 8 месяцев назад

I totally like your approach, Jarad. It's true that with everything in the universe based on vibrations this is a factor that will enter into any moving mechanical pieces and parts. Cold Steel tests used to put up to 600 lb on the back of a triad lock, but as you say constant pressure differs from a momentary shocking force. In real world use I have yet to see a spine wack factor in to folder use, at least in my daily usage. I'm also noticing that my MSI lock is seating further forward now than 5 months ago, so your wear-in concept may be quite valid. I would also mention that the types of metal used in mating surfaces may also factor in, which is what causes a galling on surfaces like titanium against steel. Final comment: who was doing spine whack testing 20 years ago or 10 years ago or even 5 years ago??? I think it's been thrown out there recently simply to get our attention and clicks, and hardly factors into real world usage, unless the user is using a folder when he should be using a fixed blade. If I'm wrong I'll certainly let you know... 😊

@scod3908 2 месяца назад

Assume you're out in the field, you grab your trusty folding knife from your pocket to cut something in a confined space and the blade get's stuck You pull backwards to get it unstuck, spine knocks something solid Oops, spine got a solid knock, lock fails and you deeply gash all 4 fingers ruining your day as you can't work and have to drive into town to get stitches There's no excuse for a failing lock on an expensive knife. None.

Hearing this more and more about the Ram Lock knives and I have been wanting one so bad, I am thinking Microtech came out with a Knife and lock of the year and production QC fell through the cracks. I am sure they would fix a knife for free but maybe I will waiting for this to be fixed in production. Microtech and this knife are too good for this to be so common for very long. I think they rushed it into production in 23 and it should have been 2024

@Seth45Dn 9 месяцев назад

I check all mine. Except I hit mine in palm. Just seems to be an even ground. Only have 2 that failed. A WE Beacon and my older TRM Neutron 2. But that's over 2 years old with a ti liner and im at 100% lock up. There's no more to break in. Its just wearing away now. But it stayed solid for a long time. TRM already said theyd replace the liner. But Jerad I too was curious about Medford especially your slim midi. A few times you've expressed concern cuz the frame lock is so thin.
