OK, Now it's my turn to put in my 3.75 (inflation) cents worth.
Yes testing like that IS dangerous. Yes, it does prove something. NO, it's not really wise, but does give one confidence in whatcha got. As far as the warranty inviting abuse, yeah it can, but I believe most folks that have a Yard, Swamp or Combat blade will not just turn it in if they intentionally do something they shouldn't with their knife just cause of the "iron clad" warranty. Of course there will always be exceptions, but I think few. I valued the test for this. I frequently chop with my knives and have all to frequently hit rocks or something harder than the steel. I would be glad to know before hand, that the blade would not have a major failure from this (I have broken more than one knife, clearing away brush etc.) Would I want to do these tests, NO WAY, I've hurt myself more than once from doing something I shouldn't. Case in point. Last sunday in church I was trying to poke holes through a stack of about 10 papers with a "lock blade" knife. Well the lock failed and the blade shut on my little finger, <img src="/ubbthreads/images/graemlins/doh.gif" alt="" /> finally stopped by the bone! or I would have lost it at the first joint from the tip. <img src="/ubbthreads/images/graemlins/banghead.gif" alt="" /> Don't mean anything really just rambling at 0530 in the morning while waiting to get off at 8. I hope this post makes some sense, if not I might just remove it later.
