Spine whack test?

[T. Erdelyi]

IBTM.

I've learned a lot about knives in the 50 some years I've used them, there's no reason to whack the spine, it serves no purpose and proves nothing, Google key bumping, this is why spine whacks prove nothing, vibrations travel through the pivot to a leaf spring of some type which is essentially a tuning fork, find the right frequency and voila it moves, beat it rhythmically and rapidly and eventually you over load and a sympathetic vibrations blows the whole thing apart also look up The 1940 Tacoma Narrows Bridge while you're at it.

Spine whacking only prove that the person doing it doesn't know how to use a knife. Hey you could use a Rolex for a hammer, (only Matt would seriously try that, only man I know who takes an expensive watch and marks it so it's not about the name but what's inside attitude Charlie Mike rocks it reality style) but seriously, wouldn't a hammer make a better hammer?

Probably the second most useful thing a knife ever did for me was untangle a jumped bike chain jammed into the bike's frame by pedalling force (which force was of course abruptly stopped!)

The work involved 50-60 full spinning force spine wacks, unto metal, into the narrow confines of the bike frame, where no other tool would have been narrow and yet heavy enough to be used. The chain finally moved, saving the bike and the trip.

The knife was a Cold Steel Pro-Lite, 4" blade bowie with the double hump styling and oval opening hole. Plain edge. It never occurred to me the knife could possibly fail, and I would have been shocked, not to mention out of a bike, and a 400 miles trip, if it had... In that failure the bike could not even be pushed: It would have had to be carried...

Spine wacking is a touchy subject because some high end knives fail miserably. That is the only reason it is controversial.

& just think if you'd wound the wheel and cogset backwards the whole chain would have unwrapped with no drama.

The more you know.

Just wear cut resistant gloves if you have doubts about the degree of lock reliability, problem solved, now use you knife as an impact weapon.

Don't get too logical now Ted.

That says far more about the knife owner than the knife or the test.....

No it wouldn't have, since the chain was so tight it acted like a single solid vibrating piece of one-piece metal... It was jammed as if it was welded in place in the FRAME. It was jammed in there by full force pedalling being stopped cold, so there was no way any amount of manual strength could have pulled anything out... It was only the vibrations from tapping the knife spine that could ever have un-jammed it...

Don't comment on a situation you didn't see...

Are you expecting that to happen? You cut with the edge side.

And "your strength" or mine? 'Cause even 10% of mine is pretty devastating. Scary even.

I thought is was funny homie...folks take their whackin real seriously....every one of my friction folders failed - to the rubbish bin with them. how can I face my squad of tactical operators with such inferior tools? I dont even deserve this code red mountain dew...:thumbdn:

Yes it would have. What you describe is common and it's an easy fix.

It's just simple physics to undo.

No vibration voodoo, no welding.

Your advice will do anyone else this happens to a serious dis-service if they do as you did.

Especially if you got one of those inferior knifes that can't take a spine whackin.

I didn't know that people go to these lengths to essentially break something that is not supposed to. To me, it's like loading a gun and intentionally misusing it to defeat the safety features to get the thing to fire.

 

[Leftytwogunz]

^ It is done by the same crowd that puts knives in vices and hangs weights off of them in an effort to tell us that lock strength is the determining factor in knife quality.

It's more like a gun bursting into fragments because you used it to pistol whip someone.

So you're agreeing that, by abusing an item in a way that is not considered intended use, problems will arise? Thank you for proving my point.

 

[Hickory n steel]

It does give us more confidence in our knives though, but I don't know if I'd stop using a knife that didn't pass. I have no problem using a slipjoint, so I know not to rely on a knifes' lock to keep my fingers safe.

 

[Sosa]

Yes. It's also good to know there are robust designs that can withstand abuse if the unexpected should arise.

Ditto. This subject is so ghetto. The test is useless.

 

[Sosa]

im convinced. I'll pay top dollar for the lowest scoring lock in the industry.

So... You're saying there can be a happy ending to spine whacking?

WHAOOO!!!! Here a Whack, there a Whack, everywhere a Whack Whack.

 

[Final Option]

Read what I just posted above about stabbing. This is not about batoning, or about that thread what so ever. This thread has nothing to do with that other thread either. So, to me... your comment was less than useless. Please keep comments to something relevant.

Wow did not mean to get you so upset, stab and spine whack to your hearts content. Spine whacking, batoning and stabbing with a folder brings out all the inherent issues with a knife that folds, that was my point. And maybe your thread is also useless seeing that we are just going over plowed ground again.
