@walkertr77: I started my knife collection in the army. Originally it was for utility (you should always have a pocket knife on you, that's something me and Stone Cold apparently agree on) and defense. Then I started getting knives you can't just buy at any store. Then I got a bunch of knives from my dad before he passed away (and after he passed away)- so now I have "artsy" knives. I don't mind artsy knives, they are nice to collect like paintings if you have a place to put them for showing off, but they are impractical. Most of them wouldn't be something I'd prefer to use for defense or utility. My favorite knife is much more low key.
I do wish I had a camera to take a picture of my knives (I'm actually pretty proud of a lot of them), but these days it's mostly just stuff I collected a long time ago over the years. That and again it is good to carry a pocket knife, but I can't carry most of my collection on the street as they are to long to be legal to conceal or even have on my person just walking about. Knife laws are weird, although I live in TX so I don't know for sure, but it's probably less stringent unless you actually got in trouble for something else. It'd be like... an addon to the trouble you're already in.
@triviaman09: your comment makes me wonder what America you live in haha
Most of the people I know (all around American-East to West, North to South) carry a knife. Several people I know collect knives for fun. It seemed to be a common hobby as I was going through the Army, even.
