Can I ask why you consider a knife a weapon rather than a tool, and therefore not worthy of carrying in a "happy place"?

I've carried a knife since I was a child. Even in school when I was a kid (back then it was perfecty OK to do this, before the sissy ninnies took over). I can't think of a day in my life when I haven't pulled out my knife to do something. Cut a string, trim a coupon out of the newspaper, cut open a stubbornly packaged bag of peanuts, whatever. I've never stabbed anybody nor even thought about doing so.

I don't understand the fear some people have of one of the oldest, most useful, and most mundane of tools ever invented.
