Spine whack test?

The spine whack test is inherently flawed. It replicates, in no way, pressure that a knife in the hand would put on a lock. Whacking the spine causes vibrations that cause the lock to release, not fail. Test your knife carefully in a situation that you would be afraid it would fail, if it fails the knife is defective. Out of curiosity, I have done a spine whack test that cause the lock to release, but I am not afraid to use that knife.
 
I'm a fixed blade guy all the way, I don't even carry a folder any longer...I honestly don't even know what the 'whack test' is aside from contextually....that said, why not just let the guy (OP) post what he's interested in? So what if he started a similar, or even equal, thread a while back? Is that a Bladeforums shame worthy offense? The guy knows that fixed blades exist. He's just wanting to hear what his BF bros have to say about the 'whack test'. I had a whole funny thing written about the whack test, but I Backspaced it, because I'm better than that.

Spine whack test ? Well , you guys want folder knife to open easy as by thoughts and in same time you want knife to past Spine wack test ??? I do not know who invented folder knife , but I am sure that his idea was to make knife which can be carried in pockets for simple ordinary task during the day .........Now , go batoning some hard thick wood and come beck here to complain how weak is your folder :D
 
A spine whack test is a stupid sales gimmick promoted by a company overstating the only decent attribute of their product.

haha, that was something different. Same knife though :P I mean, I understand how batoning is kinda outrageous. That wasn't the point, but I mean if you hit a knife with maybe, 10% or less or your overall strength and it folds... wouldn't that concern you?

Folds but not broken. Right? I think spine tests on folders is silly. If I choose to wack the spine of my folder, it most likely would be during hunting season to cut through a bone. My Schrade 250T always did just fine the few times I wacked it. Sometimes I just muscle up and cut through a bone.
 
Since this topic has been chronicled all over here and the tube, here is my contribution.

Honestly,
The Spine Whack Test is very cleaver. Dude has made millions. So make fun if it all you want. Haters Gonna Hate!

Seriously,
We all know there are some Spine Whackers amongst us whom have yet come out of the Spine Whacking closet. Let the records show, I am a Full Fledged Whacker. When I was a teen I did tons of Spine Whacking. That is until my Mom caught me Spine Whacking. She told me son, let me show you how to Spine Whack so you become the best Spine Whacker in the West. Plus the chics dig it. From there, the Spine Whacking just got plain outta control. Once, I even tried to Spine Whack a chicken, but that is a story for a whole other thread. I will just leave you with, Don't try to Spine Whack a chicken, cause they have big hard peckers!

Entertaining, yet strange....

Not as strange as the OP's continued obsession with "spine wacking"

If there is truly one aspesct of a folder that does not need to be constantly examined, it would be it's ability to take strikes to it's blades spine....unless you work in marketing for CS....

what are your thoughts on the spine whack test? One of my favourite knives, fails it pretty easily despite it suppose to be a "hard use tactical" knife. Which makes me more hesitant to use it in a hard use role. Now, i don't do this test to baton or even hit hard. But, there are many scenario's where you can inadvertently put stress on the spine of a knife (example stabbing and slightly hitting above the tip of the knife). To me, that seems like a safety risk on a "hard use knife" that doesn't sit well with me..

To clarify, i don't mean hitting the knife hard. Like really smacking it on a table. I mean, with minimum effort 10% of your strength or maybe 5% and the lock disengages.

Ok I'll bite.
What are some of the other scenarios? Can you give me like a couple that don't involve knife use found in call of duty? It seems like if we are stabbing something and the blade punctures, it really wouldn't close on our hand at all.

Obviously, if we've run out of rifle ammo, pistol ammo and then have to use our cold steel knife to finish off the terrorists BUT he has on rifle plates, so no penetration, knife folds, cuts off my fingers and bad guys win. I get that one. What are all the others?
 
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.
