lot's of people doubt slipjoints as a heavy use knife and all. i don't get it. I've used a slipjoint from my grandpa (at least 50-60 years old) and it's never failed, from spinewack tests, cutting through massive branches, and anything in between. i would rather use a slipjoint that a knife with a linerlock, frame lock, lockback, axis, etc if i the drawbacks weren't so much for so little (slipjoints tend to not be as tacticool as liner locks and if it opened as easy, since slipjoints tend to be tight). it annoys me when someone goes like, "nice knife, but it probably would fail easier since it's a slipjoint". really?
