I sent in my BM 527 for warranty work. I called them and explained to them that I broke the tip of my knife because I dropped it on a tile floor. I was fully expecting to have to pay the $25 fee to replace the blade. He basically said "we can replace it for you this time, just be more careful". He didn't even make me pay the normal $5 shipping fee. Let's remember guys: a warranty is a guarantee against defects, not misuse. A knife, especially a folder, isn't designed to be used as a prybar, a screwdriver, a can-opener, and breaking your knife while you are doing any of those things is probably not going to be considered a defect, but rather, misuse.
If that had happened to me, I'd have simply changed the tip shape, maybe shorten the blade a little, and take advantage of the fact I'd be redoing it all, to give the blade a nice, hand rubbed finish. And who knows, perhaps make a set of scales for the knife, and totally personalize it.
