Not only do you run the risk of them wrecking your blade, but NKP are seldom use to "sharp" knives--much less "scary sharp" as most of us keep ours

But they also run a real risk for an ER visit, and then they'll attempt to shift the blame with questions like, "Why didn't you tell me it was sharp?" or "Why do you keep your knives so sharp?" or "Why didn't you warn me this knife was dangerous?"
Is the public at large really that accustomed to using butter knives, screwdrivers, and car keys to cut with?
....the answer--- YES! :thumbdn:
So next time someone asks to use your knife, respond with, "Whaddya need my knife for, you got a set of car keys don't ya?"
