If someone asks to borrow my knife, I reply with what do you need it for?? , and they will either tell me or show me what they need cut, and I will go cut it for them, If its for prying or as a screwdriver I tell them no. As a general rule, and for having had several knives broken by idiotic people , I do not let anyone use my knives, I rarely let anyone even touch them for fear they will do something stupid with them. I had a guy about 2 years ago eyeballing my little FRN native and he asked to see it , and I said O.k., Will idiot looks at it and takes off, I'm on the line at my job so I cant go after him, but I can see him about 40 ft down the line from me using the twisting and popping method for removing zipties, after he torques the zipties off, he uses the little native to pry industrial staples out of some boxes, then he brings me the knife back, Which I had just mirror polished the edge FWIW, and It had some nice chips in it , I told him he owed me 50 bucks. He replied for what? I said you ruined my knife and pointed at the chips, well he liked the knife, and said he was gonna try to buy it off me anyway , so he bought it, and after he paid me, He asked me if I would take it home and resharpen it , Which I did...poor little native haven't seen it in years and no telling what kinda life she's living now....
