Lee Valley Rotary Mower Sharpener

Used in a hand power drill, this grinding wheel quickly sharpens the blade of a rotary mower. A non-turning backplate holds the stone on the blade at the correct bevel angle. The stone is reversible. It can be used to sharpen spades, hoes and edging tools as well. Good for about 10 sharpenings. (Not for use on mulching blades.)
