Every single time I let a friend or acquaintance use one of my knives I feel nervous that they are going to dull/chip the blade. Even if it is for something as simple as dicing vegetables or cutting paracord they might ding the edge on something. One time another kid asked to see one of my knives and then tried to stab it into the table we were sitting at, (I would never do such a thing) but the table was actually concrete painted brown to look like wood!
I literally felt a pain inside of my stomach from the concept that someone would do such a thing with a knife. Luckily it just flattened the tip of the blade a bit and did not break it off. Quite a few other times I have lent someone one of my knives for about an hour, and I get it back to find a whole bunch of flat spots on the edge. Usually it is not such a big deal, but it's not fun when I loan out a more expensive blade and it comes back dirty, scratched, and used with no edge discipline at all.
($200 BM940 is expensive to me. No Sebenzas yet) I became so tired of people asking to borrow my knives that I decided to start carrying a knife specifically for loaning out. I picked up a Victorinox Pocket Pal from CutleryShoppe for about eleven dollars. Possible the best eleven dollars I have spent in a long time. I let someone borrow it, and don't even care when it comes back dull, dirty, and scratched. The simplicity of the design makes it so easy to maintain and sharpen. I was so happy with it that I bought five more Pocket Pals to go into various kits around the house. I've also noticed that people seem less alarmed when I whip out my Pocket Pal in public, compared to when I take out my BM940 (or my Endura 4 Spyder-Edge which I rarely carry because it looks gnarly). Do you guys carry designated loaner knives on your person for this reason or am I the only one who gets absolutely paranoid when I let someone use my knife?
