I've liked knives since grade school. Can't really remember ever being without one.

There's just something about a blade and handle that attracts me. PLUS they are first and foremost a TOOL that can be used for many different things. Plus they are also a weapon, albeit a last ditch weapon, but they're better than nothing. I've been in countries where it is the ONLY "Weapon" you could carry, saved my bacon a couple times.

Other than this, I just like knives, the shape and what you can do with them.
