If I was you i would use 1084 or 1095 hi carbon steel. Shape, grind, everything but don't take the edge down to its final sharpness just yet. Heat knife with a rose bud until a magnet doesn't stick then quench in vegetable oil. Wipe the blade clean then into the oven at 400 degrees for 2 hrs, let cool then 400 degrees for 2 more hours. Now you have a heat treated and tempered blade. Finish as you wish and the edge will hold its sharpness. Any questions just pm me i make knives for a hobby and will help you if you need.
