"Why do you need a knife like THAT?" I used to get that a lot. My answer "I don't need it, but it makes things so much faster."
my knives always tended to draw two people. People that liked knives and wanted to handle/inspect them (which I honestly don't mind) and people that were afraid, because I had a knife that looked like "that"
(balisongs, half serrated, auto folder, tanto, razel) Now I carry three, and its the third knife that conceals my other two.
Case sodbuster jr. is now my basic all round go to knife (Thank you SM). Its the one I let "the public" see. Its also the one that I'll let someone borrow. I can't tell you how many times the sight of it has started a conversation that begins "Oh thats like the one my **** used." I think its the distinctive color.
The others, a fixed bladed tanto and kerambit, generally don't see the light of day anymore, but that is alright with me their edges (Thanks to The Tourist) are a little more delicate than I'd like to use for utility work. I also got tired of telling people "I told you" when they've cut themselves inspected the edge with their fingers, AFTER I tell them the edge is stupid scary sharp.
