I just started grinding knives, and I'm looking for a better (faster) way to do the rough shaping. Right now, I'm using a hacksaw, a dremel, and lots of patience, then I finish off with a belt grinder, but I'd love a more efficient way to do this. I don't want to spend the money on a bandsaw yet, but I can justify buying a sawzall for under 200, because of all the other things I can do with one. Is this a good idea?
