It boggles the mind! How can people be scared of a simple tool?
If you cut me free of a mess like that I would have shook your hand till my arm fell off.
Wouldn't you have had your own knife on hand, to cut yourself free?
Recently, at work, one of my coworkers was struggling with a cardboard box containing a toner cartridge. I offered to help, and she said "thanks." So, I took the box from her, set it on a counter, and reached into my pocket for my Queen canoe. Keep in mind that this is a traditional pocketknife, and a small one at that. I opened the box, and the plastic packaging inside, after which she winked at me and said "I won't tell if you don't."
I asked her what she meant, and she said "You know, having a weapon." I was almost speechless, but managed to ask "Didn't your grandfather carry one of these?" I explained to her that it is not a weapon, but a cutting tool, and that it works much better than holding an open pair of scissors by the blade to rip through a cardboard box.
It's funny... She and I see eye to eye on most other topics, including music, politics, office dynamics, etc., so I know that she was not personally offended by my carrying a pocketknife. I think she meant to say "watch out so you don't get into trouble." Regardless, I've used it to the benefit of my boss(es) several times, and they're obviously quite comfortable with the idea of a young man totin' a handy little pocketknife -- they probably did when they were younger as well (they're in their 60s, and I'm in my 20s).
