I live in a city. I do not carry a knife of any kind, and, to be fair, the times I've gone "gee, I could use a knife right now" can be counted on the fingers of one hand (which means a maximum of 5, not 4, you knife freaks :-p). Honestly, all fine and well if you live in the middle of nowhere, but I'm one of those people who thinks serious knifes should be illegal just as much as guns. Heck, I don't even box cutters with any regularity, only in construction work or such. You can open a box with an enveloppe opener just fine.
