Hmmm... I detect some of all three in me.
1) I can't resist a good looking knife. (But the real pretty ones that I have don't get carried much, so I tend to OOH and AH, but not buy them.)
2) It's a tool, not a fidget toy. (I like to carry a knife capable of hard work, but I don't put it away wet. I take care of my tools.)
3) I don't prepare for random muggings,. (But I do carry a flashlight and something to pry with so that I don't mess up the knife. And I keep spare batteries, extra light bulbs in multiple wattages, and suchlike in the garage, so to a certain extent, I'm a "prepper". )
I'm just a bit of a random guy.
