What constitutes abuse to one person may be perfectly acceptable to another. Splitting a bag of cement with a beater knife is okay for some, but not others. Some guys will walk back to the truck, grab a chisel or something, and walk back. Others will just use the knife they have in their pocket. Sure, they'll get cement in the pivot and dust in the handle, but thats why they carry it. It isn't misuse, just use. I think the abuse can be applied to what comes after. Do you clean and sharpen or throw it on your dresser?
I can tell I'm in the minority (maybe alone) here. I guess I won't be borrowing any of your knives

. For what it's worth though, I've yet to break a tip, create unfixable blade play, break a lock or chip a blade past something I couldn't sharpen out. I've only got a handful of knives, and they all get used, no safe queens. I'm not talking down here, I WISH I had safe queens

. But they all stay clean and in working order. I've never thrown away a knife because it broke, but they've all clipped ties towards the metal, sliced bags of cement, cut linoleum and carpet, parted gritty and sandy rope (a lot of that), scraped gunk from corners, and deglued decks. Okay okay, I won't ask to borrow your knife.
