i've never seen this video before but ive heard about it as i've (mostly) lurked the crk forum here for a while but do have a couple comments.
1) i know that knife was thoroughly abused, but i was fairly surprised about how easily it did fail the spine whack test- even on a finger.
2) that being said, i would like to see how other knives of similar build and quality (strider, hinderer, bradley alias, even spyderco and benchmades frame lock knives) would hold up to the same tests. I think it's unfair to say look how badly knife A failed, without also testing knives b, c, d and e.
3)he never really shows or explains why it fails, just shows that it does fail, i would like to see exactly why.
now i didnt read the old thread that esav posted so some of my comments or questions may have already been commented on or answered.
