I made this boxy carving knife out of a piece of metal that might have been part of our old doorbell. I used my angle grinder with a standard grinding disk to get the rough profile, then a flat sander on my drill press to get it closer to final. Then I used my "strip strop" (my band saw converted to a strip sander, with a worn cloth sanding belt) to finalize the edge. It is not the sharpest knife, but it's the first one I've made from scratch. The handle is made from scrap cedar that I picked up at Home Depot or Lowe's. I used my strip sander to round over the corners of the handle. Considering that my budget was zero, I think it turned out pretty good. The main mistake was that I ground the edge on the wrong side. I picked that side because it was more ergonomic to grind, but it turned out to be a left handed knife. This knife can be used for opening boxes or carving if you are left-handed. It is sharp but not pointy.
