I wouldn't exactly call it a non-knife moment, but this is the encounter I had earlier today. Keep in mind my EDC is a BK9, and most people never say a word about it.
I was at the store in the checkout lane, and the older woman behind me asked if the thing on my belt was a knife. Naturally the answer's a yes. Naturally there's the question of why I'd carry something to big. The first part of the answer was economics, and how some quality folding knives can cost over $100, whereas mine was $75 on sale. She didn't say much, but you could tell that she could see the logic in it. Then I moved onto the practicality of carrying it, and how it came in very handy for processing wood and tree limbs that get in the way. By that point I couldn't tell if she was agreeing with me because she really got it, or because she simply didn't have anything to offer up as a counterpoint. Either way it ended on a positive note.
