I like to use the contact wheel on my belt grinder with a gentle pulsing action to take the cheeks off the edge and blend it into a nice convex. I start with the 36 grit Cubitron or 80 grit "Gator" Trizact belt depending on how much material I'm taking off, then a 200 grit cork belt loaded with emery compound followed by a gritless cork belt loaded with the same compound. Brings it right up to a mirror.
