They have a separate attachment intended for things like mower blades and axes; costs about $50. It is very aggressive.

I have the blade grinding attachment for chef knives that uses 1"x18" belts instead of 3/4"x12". Had to buy it as an accessory at the time but they now bundle it as the Elite Sharpening System for an extra $50 over the KO.
