I think we need a NSFW subforum for this topic
Can't say that's ever happened to me with a multi-tool, but I have inadvertently fallen asleep with one of my zebralights on my shoulder while reading, or my Quark mini AA, and woken up in the middle of the night with it gouging me in the ribs or the like...
Thinking of having Tim sign it for me ...."thank you for signing that Mr. Leatherman. You know, I've had a lot of tools but thats the only one I've actually slept with"
I often have various opened folding knives sitting on my bed that I tend to forget about, one of these days I'm going to cut myself.
