Q: How do you sharpen a rotary mower blade?
Chuck this lawn mower blade sharpener into a hand power drill, then guide the stone across the blade; the backplate holds the correct bevel angle for you as you work.
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.)

No, this rotary blade sharpener isn't designed for mulching blades, which have a different edge profile than a standard rotary blade.
Beyond mower blades, the stone also works on spades, hoes and edging tools that need a fresh edge.
Expect about ten sharpenings from each face on this lawnmower blade sharpener, and since the stone is reversible, flipping it over roughly doubles that before you need a replacement.
