They do state on their warranty that they don't cover wear and tear or rust.
However, their "no questions asked" warranty does not say you will not be ridiculed by them, and they do like to ridicule people that send in broken knives. For instance, check the current warranty page and see what they call one of their customers that sent in a knife that had been shot -

No questions asked, but you are an idiot if you break a knife.
I quit buying anything from them when they ridiculed the kid that sent the knife in, broken, and told them he and a buddy were using it as a throwing knife while on a camping trip. They have since removed the thread, but they gave the kid a pretty good public dressing down.
They have no class, in my opinion. The knives are pretty good though, and cheap so just buy another one, break that one and send it back in for the no questions asked warranty.
