VIDEO: Spine Whack Testing 3 folders

[Ankerson]

I tested 3 knives that I have done videos on before to show that they will pass the spine whack test. 2 of them are framelocks, the Strider RW-1 and ZT 0301.

IIRC in the CS Proof videos they hit the blades a lot harder against the wood, but I unterstand if you don't wanna do that to your knives. Thanks for the video anyway.

I hit them harder than you think.

I was snapping my wrist hitting them....

No I ididn't hit them as hard as Andrew Demko does.

We began spine tapping knives in 1981. I believe we were among the first as none I have every spoken to had ever does such a test when we began. None of the factories that we were working with had ever heard of such a thing and most didn't like the idea, but we kept them honest.

To hit the knife any harder than Ankerson did is foolish. The purpose of the test to determne reliability not strength. For strength, we just break them on a computersized breaking machine and get graph read-outs of the break. Then we analyze the break to determine what might need to be stengthened if it didn't meet our preset standard.

Nice job Ankerson.

Thanks Sal. :thumbup:

If I was denting the wood I figured I was hitting them hard enough.

Try to hit with the tip of the blade.

Fulcrum is much bigger and locks that seemed to withstand spinewhack fails with much less "hit" force.

I will make a deal with you.

You send me your knife and pay shipping both ways and I will be more than happy to break it for you on video and send you the pieces back.

I have no interest in breaking my $240 and $500 knives.

To get the Strider and ZT to fail I would have to break them, the locks are that good, I would have to hit them both with a sledgehammer to get them to fail breaking the Ti or the blades.

The CS Voyager would also be hard to get to fail.

ROFLMAO!!! Good call Ank, :thumbup::thumbup:
Yeah any knife can be broken if throughly abused enough. I think you've proved you point way more than most guys would abuse their expensive knives.

Yep.

On the framelocks, as well as linerlocks, I have noticed that rapid light taps can induce lock failure. As such, when I test framelocks I test both slow with "hard" and rapid with "light" tapping.

I can't remember who brought up the rapid light tapping, but he was right as to such a stress causing failures in knives that withstand the slow and "hard" taps.

Hitting it any harder is unnecessary abuse. I think he did just fine with the way he did the test. Thats all you need to know for how it will behave for a real world occurrence. Now use them and enjoy.

Ankerson, thanks a bunch for this vid. I have the ZT. My favorite folder. Although I have never doubted its lock-up it was cool to see this test. Thanks again. :thumbup:
