Spine whack test?

[3Guardsmen]

Crap... I happen to carry mine right now. I just checked it and... well... give it a few taps agains my wooden desk here in the office and it help up well. The liner lock seems to be pretty well centered. Anyway, thanks for the heads up. I will keep being as carefull from now on as I have been before.

Glad to hear it, Mikel_24! I hope it's because Leatherman took all those complaints, and they got few, of their liner-locks failing seriously and decided to do something about it. A few people here reported that, after sending in their Charges and Waves with weak locks to Leatherman, Leatherman sent their multi-tools back as is, saying they were "within specs." Be safe!

I have a few problems with this test. First, there doesn't see to be any agreement on just how to conduct it. Some say, half an arms swing against a desk. Others say a light tap on a carpet. Second, a folding knife should be used with extreme caution, whether or not is passes this test. After all, a folder was designed to fold.
I have indeed tested a few of my blades, but fail to see what has been proven. Finally, does anyone know how to repair chipped formica counter tops?

Replace it with granite. Or G-10.

Spine whack test - reminds me of the movie Donkey Punch. You can joke about it but you should not do it too hard...

The spine whack test is the most retarded test ever. When would your knife be under that much stress from that angle. Its like locking your gate and driving a trailblazer through it and then say "Man, that gate has a weak lock on it"

From this post it's obvious that you have never had a locking folder fail the SWT.
In fact, it sounds like you really don't know how to conduct the test.

You seem to think that it takes alot of force for a defective lock to fail.
Well, it doesn't.
All it takes is a little wrist snap onto a firm surface for a defective lock to fold.

Believe me, you will be amazed at how little force it takes once you get your hands on a defective locking folder.
It's not like driving a Trailblazer through a locked gate....it's more like turning a door-knob only to have the knob break off in your hand.

If I ever get my hands on another defective locking folder, that fails the SWT, I'm going to start a pass-around thread so everyone can see exactly what I mean.

It has proven that the lock geometry was correct for that knife, and that the lock is reliable.

And you didn't need to chip your counter-top....you could have put a towel down first.
After all, all it takes is a little wrist snap of force to determine if the knife is defective or not.
Trust me, when you get a bad one, it will fold with the greatest of ease.
