Abstract:

A device for use with a portable electric drill having an abrasive wheel attached thereto for rotation thereby. The device includes a base for holding the drill in a substantially horizontal position and a clamp for holding a lawn mower blade. A rail is adjustably attached to the base. A rail follower is slidably attached to the rail for reciprocating movement thereon substantially parallel to the longitudinal axis of the abrasive wheel. The clamp is fixedly attached to the rail follower. When the rail is adjusted so that the cutting edge of the blade held in the clamp is in contact with the abrasive wheel and when the drill is activated to rotate the abrasive wheel, reciprocation of the rail follower will cause the cutting edge of the blade to be sharpened.
