Spine Whack Test

nightman said:
Do you believe the "spine whack test" is a legitimate indicator of lock integrity? If your knife fails this test, do you feel it merits a warranty return?

Only if you are in the habit of using the spine as an impact tool instead of using the knife as a knife.

So do you guys think cutting a pizza with extra cheese would be a legitimate indicator of lock integrity? Or would that be considered abuse? And if it's not abuse and the knife fails the pizza cut test, would that be considered grounds for warranty return? :confused:

Peanut butter. No cheese, just peanut butter. And a beer?
 
In a perfect world, Id' have a folder that can survive spine whacks like a fixed blade but for the moment, I think that no manufacturer can make a folder that can reliably survive repeated spine whacks and overstrikes.
 
Ya know, it is a "perfect world" for me, and I do carry fixed blades most of the time. Which is why this thread is such a big laugh to me.

You are mistaken, Triad lock can shrug those off all day. I dare anyone to try this with any other locking system and it will fail miserably. http://www.youtube.com/watch?v=pDDQGmW2Hrg

EDIT: I just realized that I messed up the link it works now :o

So who said beer?

You flamers need to go elsewhere so I can get some legitimate input here. I will ask again: How about periodic testing of the lock with a LIGHT spine tap?

What good would that do? What would it show? What does "LIGHT" mean? How many grams of weight, joules of energy = "LIGHT"?

In statistical analysis, you need a minimum of 36 exact knives to be "whacked" to produce anything considered scientific data. That is the minimum. Then you need to repeat this using 36 different knives for each degree of force you want to measure.

Whacking on only one blade until it fails tells you nothing. It was invented to waste time on YouTube.
 
I vote for the Becker BK-2 or the ESEE-5 for best results in spine whack tests - I don't think you'd have to worry about either of those knives folding on your hand.

I agree with those that say to treat a locking folder the same as a slipjoint - think of the lock as a convenience rather than a safety feature. Don't stab with a folder - ever!
 
Did you guys watch that video? I mean seriously there is no other lock that can take hits like that without failing or developing severe play. And post count doesn't mean anything...

But you should still spine whack your Randalls to make sure they're safe to use.

I guess you believe in Homer Simpson too.

Make your own video with full force spine whacks and overstrikes and do them all day. Maybe you'll get lucky.

Like those guys who say size doesn't matter also have little ones. ;)
 
A thread about the spine-whack test has now turned into a debate over the Tri-Ad lock. If that ends up turning into a fight about the merits of Cold Steel's marketing, we might end up with a new record for most dead horses beaten in a single thread. ;)
 
I don't have money to waste on destroying expensive knives, and that last comment I mean really :barf:
