This is an 80-year-old outdoor knife. It's a custom knife, with paracord wrapped around the Mark 1. I made the sheath myself. I used vegetable-tanned leather and brass rivets, and added a hook to the belt for easy attachment and removal. I made it so the grain side of the leather is visible, just like the sheaths from World War II. I've used it once, so it's a little dirty, but it's still usable. It cuts like a razor.
