A lot of the knives I collect are limited edition. I have knives from Buck, Smith & Wesson, SOG, Benchmade, and Columbia River just to name a few. Some I use for pratical purposes and some are just for show. I keep at least one knife in every vehicle I have just in case I need it for emergency repairs or anything else that comes up. There's different things that appeal to me usch as the finish, the blade edge, the blade curve, or the blade style. I also look at the handle as far as finger placement and comfort, as well as protection.
