Zaph1, it is 1095, 7 inches long, split right down the middle between blade and handle. Bone scales. It wasn't really designed for a specific purpose.
12345678910 and bladsmth, thanks for the link and suggestions. The plunge issue will be corrected on the next one.
Next steps for me are ordering some 1084 so I can heat treat myself, and building a small heat treat oven. And of course research research research in between.
