Abstract
Hand held sharpening device for tools and instruments having single cutting edge type blades such as lawnmowers and the like. A hand grip body has a forward nose section in which is located a recess for a single blade having two sharpening edges. A retainer member attaches to the body and holds the blade in the recess. The retainer member and the cutting edges of the blade extend beyond the front end of the nose such that two sharpening slots are defined. The device is also provided with a hand guard.
