Great explanation of the principles of grinding. I had no idea those discs weren't flat.

Is there a preference as to witch side to grind the comb and and the cutter?
It seems like most people are grinding the combs on the left hand side of the wheel, and the cutters on the right hand side. As far as I have understood.
What happens if you grind both combs and cutters on the same side of the wheel, like on some portable grinders?
