I'm concidering buying a Tormek but have a couple of questions. I own a Delta 12 1/2 planer that uses double edge blades. The blades are pretty narrow and I'm not sure if they can be sharpened on the Tormek. If they can't I'll need to spend my money on a planer before buying a Tormek to sharpen the blades. My other question is this. Can you sharpen carbide jointer/planer blades with the Tormek? Thanks for your time.
