I am learning to sharpen my chisels and plane blades with water stones. I realize the water stones aren't much good for aggressively removing material from a badly damaged blade. I don't own a grinder yet but I am wondering if a 3450 rpm bench grinder has any advantages over a Grizzly T10010 (Tormek clone)? What can a bench grinder do that the T10010 can't do? I feel there is less risk of burning the metal with a low rpm T10010 so I am leaning towards purchasing that. Advice would be appreciated. Thanks, Andrew
