Please.

And videotape the process.

Ideally you should clamp the knife horizontally and on its side, about halfway down the blade.

At this point please add weights to the handle and keep adding until the knife breaks.

I'd do this with my own, but, oh, wait - no I wouldn't. But I bet KAI has.

Wonder how many pounds it takes - any guesses? Wonder if someone would tell us?

Do you think you could cause a catastrophic break in the knife with your arm by prying with it?

Whatcha think?
 
Well, mostly I guess I'm just curious about things.

I have this knife and it feels extremely stout. More so, frankly, than some fixed blades I own. That's one of the reasons I bought this knife. Also, this is a knife that I plan to carry and I'd like to know how much force I could put into it in an emergency. Not trying to be offensive. If this doesn't interest you, that's fine.
 
Also, I am not actually suggesting that anyone break their 0560. I was trying to be funny. I forget sometimes that my humor doesn't come across in type (or sometimes in person).

That last part was another joke.
 
Powder steels have an advantage in being fine grained and tough, but extreme flexing + lateral loading is not something they excel at compared to ingot steels.

Pretty sure the lock would fail before the blade breaks.
 
The lock, bar would probably bend or shear at around 100lbs. Titanium framelocks are all roughly the same from what I can tell.
Yes you can build them stronger, but it makes them harder to unlock, so no-one does it.

But, this is irrelevant, unless you plan on doing pullups with your knife in a vice every morning.
Most people are never going to come close to putting that much pressure on the lock, what they probably will do is apply a shock load from swinging the knife around and hitting something (testing with static loads tells you almost nothing about how it will handle a shock load). What you are probably looking for is a reliable lock, a strong and unreliable lock is worse than a slip joint (you know what to expect with a slip-joint). Kershaw does lock geometry right, and when you have the Titanium lockbar contacting the blade tang you get that classic "galling action" that makes Titanium so much of a pain to work with.

Your 0560 should be very reliable and more than strong enough.
 
Um, I am a curious person by nature, and have been know to test knives abilities to much more than cutting.

As a matter of fact, its kinda my job sometimes.

I plan on seeing how well it will cut repeatedly, through thick cardboard, and see how well it holds up to dirt and grime, as, those are two things that I know my knife come into contact with.

The only vice coming near my 0561 will be whiskey, and maybe the occasional woman. Those are really the only vices I have. :D

Gonna have to say, no, to the lock stress test on my badass 0561, mon frere.

Wow - I just watched that Neptune guy and have to agree - he probably actually would break one.

But I hope he doesn't really.

I was hoping that MAYBE someone in KAI had already some sort of standardized test and might share... Probably not.

Undoubtedly they do, but that is something I like to call, "industry secret".

See, there are alot of things that companies don't want you to know. And I agree with it. I'm privileged to know some things, nothing about Kershaw, mind you, but with several other companies, and custom makers. That's why I call it a privilege. Not everyone will get to know, with out being in the middle of it.

Not to worry, I'm sure someone will do it.

I'm sure Jimmy and/or Thomas knows this stuff (not sure if they'll release it though). Theor R&D guys like to break stuff for science/fun.
 
Yeah - as I was thinking it through I could see several reasons why companies publishing stuff like that might not be a good thing. There'd be a bunch more 16oz. "pocketknives" on the market for instance...

Still can't help enjoying watching destruction/abuse tests. I will never be convinced that many of those tests, when done as consistently/scientifically as possible, do give a lot of valuable information - at least for knives calling themselves "hard-use".

Edit: or "combat" or "survival", etc. These knives should hold up under stress and sadly many don't.
 
A couple of things:
1. The videos of NeptuneKnives abusing knives like that tied my stomach in knots. To me it was like watching someone put a table saw blade in a bind.
2. It will be a sad day if I ever break my 0560. A sad, sad day.
