Thank you I would use thin steel to start do your ruff shaping and grind. Don't grind it to thin before heat treat. I would get treat the blade with furnace cement on the spine to keep it soft, about half the sides of the blade need to be covered. This will give the knife blade flexible. Them heat treat the blade if your using carbon steel/which is all I use/ get the blade to non magnetic and quench in oil. Cooking oil will work but I use super quench. Then drawl the blade back in a oven make sure to the edge is not brittle. Look up the specs depending on your steel of choice. Then place the blade on a thin board and use a flat peace of wood or aluminum and glue a peace of leather on the back use the hard side to do the initial sanding get all the lines out drawling the sandpaper from the handle to the blade tip make sure not to damage the tip with to much pressure. Work up in grit to the finish you want. Use the leather side to smooth the finish. Sand the blade till it he cutting edge is super thin then sharpen it. I do my sharpening on a peace of leather with sandpaper on top. I do this to get a convex edge. It holds up well. Just take the edge up to 800 grit to get a smooth tough cutting edge. Add handles to the knife before you sharpen or tape the crap out of the blade so you don't cut yourself. Is do a full tang knife with stabilized wood handles a good epoxy and flared pins to attach the handles.
