Just yesterday I was shown a coworkers brand new Leatherman. he had lent it to another coworker who returned it with the leather punch and the small screw drivers tips chipped off. What did he need it for? To unscrew phillips head screws with. Why didn't he just use the phillips head screwdriver blade? He didn't think it would work because he was told by someone else "The screwdrivers in those things never work!"
A while back I lent my leatherman to a coworker, and he climbed to the top of a 33 foot mast, cut some zip ties, and then threw the knife down without closing the blade. The blade snapped. When I asked him if he was going to replace it, he said "No, you should not have lent it to me in the first place."
My crew chief asks others to borrow their leathermen often. I asked him why he does not get his own. "Well, I can't see spending money on something that I am going to break or lose and the company won't pay me back." When I refused to lend him mine, he told me to do the job since I was so selfish. I walked the 300 feet to the tool box and returned with the proper company tool, and he got upset because it needed to be done right away. I told him I thought his earlier answer about not wasting money on using my own tools was the best way to do things. Bosses look funny when you use their own logic against them.
Also, the company policy is you cannot use your own tools. That can mean I am legally responsible if someone gets injured while using my knife.
No, I don't lend out my knives anymore.
