I have, but now only if I know from being told, from the circumstances, or from who is asking, what the intended use is to be.
I'm more careful after the person who was cleaning my office asked if I had a knife, wanted to borrow it, and proceeded to cut the vacumn cleaner cord with my Gerber Paul Model 2P. Hopefully, he did not use it to screw the screws back into the plug, but who knows. Probably cutting modest copper wire was within the realm of reason (his not mine) but it bothered me a little. Besides I did not have a Sharpmaker then. I recall being able to detect a little effect on the edge (the screws? shudderrrrr!!!) but nothing of great significance.
