My youngest son, who is a farrier, recently started making knives from discarded farrier rasps and deer antlers. He's getting pretty good at it. This is man-style recycling at its best. If anyone is interested, he sells them. They are very well-made and he puts a razor sharp edge on them as well. He also makes a hand-stitched leather sheath molded and custom fit for each knife. The sheaths are formed to fit so no snap is required to hold the knife in place. They fit tight. Below is his latest creation.
