bench grinder. Start grinding and keep it cool, I'm not a knife
making expert, though I've made a few. I'll just point out that the
machine of choice for making blades is a belt sander. Cooler,
wider, faster, better.
There are so many tools to choose from, you can make a knife many
Depending on the job, I either use a belt, a bench grinder, a baby
angle grinder, a large angle grinder, a forge. Some people I know use
EDM, and some use milling machines (I don;t use these because I
simply don't have the space).
The trick is heat control if you harden and temper the metal before
grinding, or just heat treat after shaping and finishing the blade.
