I am working on two knives for xmas gifts for my children and have completed 6 knives. Workin on my first leather sheath- after purchasing leather, thread, dye needles etc.. Didn't have money for any leather stamps at $8.00 each. So I picked up 3 ft of steel rod from local hardware. While trying to decide stamp type I was looking at knife and thought it might be cool to have the sheath border match the file work on the knife blade. So I am working on creating my first stamp tool. Should I heat treat stamp?? Thinking it doesn't need to be just for leather but would make stamp more rust resistant. Will just bring to non magnet and quench, then throw in oven for 1 temper since I don't know metal type. Also I would think making camouflage and basket weave stamps can't be that hard (filing practice if nothing else).
