TOOTH SHARPENING
Begin by chamfering shank back past edge of carbide. You do this because if it is
not back far enough the shank will hit the stump and not the carbide, thus causing a
lot of vibration. Once the shank is angled far enough back, then begin sharpening
carbide.
 Cut shank with a standard rock and cut carbide with a silicone carbide or diamond
rock.
 CAUTION: GRINDING CARBIDE CAN BE A HEALTH HAZARD. Use facemask to
prevent breathing in harmful material while grinding.
