Its been a few years since I made my last knife. I used to have a belt grinder and would grind my profiles on that. I bought a new house and don't have access to any of my old tools. So I've got myself set up with the basics. Drill press, a few files, a vice, a bevel jig etc. I am using the drill press and a hack saw to cut the blade close to the desired shape, but my questions is what type of file do you use to profile it exactly to shape, and how do you keep it at a perfect 90 degree edge all around? If I try filing it in the vice I can never seem to get it perfectly flat. I'm thinking I should just get a cheap belt sander, but really want to just save up to get a nice one in a few months.
