I got a like-new knife of Kevin's, the little Mongoose model, in a trade from a BF forumite. A nice spearpoint concealment size knife, made from his claimed indistructable special tempered O-1 steel. I was using it to cut down a piece of pine from a desk and hit a brad I didn't see in it, and it put a distinct chip in the edge. Not gigantic, but about the size of lower case letter "c" in 9 point type. That really surprised and upset me, because I've read all the "Kevin hit the anvil in his shop with a MD knife and a piece of the anvil flew off" type of claims made on his forums. So I sent it to him (Express mail, received the next day)with a short note of explanation, plus a request to redo the edge to eliminate the chip. 3 weeks go by, no word. I email, no reply. Finally, I call him and ask about the knife. "Soon" is the jist of the reply. Another two weeks go by, I call again. It takes a while, but I finally get through, and he basically says he doesn't think the damage is covered and want payment for the fix "when" he gets around to it! This goes back and forth, and finally I just ask for it back as is. Which is what he did. Now, maybe I shouldn't have expected him to back up his work since he's already shown himself, on his own forums, to be a liar when it comes to his so-called military background (This is where first he stated he was a "professional soldier for six years", then admitted it was a "typo" and was really only two years, then admitted he was a trainer for a civilian supplier of weapons systems who only "trained" real soldiers. All that was either before or after he was a boy genius recruited by the CIA. No, I'm not making this up ~ you can find it over there still!). I expect any custom knifemaker to stand behind their knives, and to refuse to regrind a chip out of a knife when your whole sales pitch is the super dooper strength of those knives, to me, is reprehensible. I will never buy another Mad Dog knife, both because the performance claims are bull, and because he didn't stand up for them when shown to be bull. Caveat Emptor!
