Just did a google search, no result. What kind of knife is this?
Columbia River Knife & Tool makes them. They are the ones that make the little folding KISS knives that people use for money clips. They're widely available at any knife shop or webbsite (I usually get mine locally at an ACE hardware). Gun shops have them if they carry a line of knives. It's just a very simple straight knife with no hilt, handle material, etc. Just a plain flat piece of carbon steel that is ground into an extremely useful knife. Tanto or drop point and part serrated or plain in either style. The handle can be wrapped with nylon cord or left plain. I leave it plain since it makes an excellent small pry bar that way, the really neat thing ablout them is the sheath. An abs plastic that can be configured for any carry position you desire; up, down, or sideways. Only about $25.00.
