ABSTRACT:
A device, for honing the axially-facing cutting edges of a rotary shaver cutter, has two parts which are rotatable one with respect to the other. Within one part there is disposed a frictional element abutted by the cutter so as to prevent relative rotation between the cutter and that part. The other part carries an abrasive abutted by the cutting edges of the cutter. At one end, the device has a first recess, on one part, which receives a finger or thumb tip, or an end of a holder, and is smooth for easy relative rotation. At the opposite axial end, the device has a second recess, on the other part, which receives a thumb or finger tip, or another end of the holder, and is formed to prevent relative rotation. The outer part has a circumferential surface adapted for frictional engagement with a running surface such as a table top. With the device held between finger and thumb, or between the ends of the holder held in the hand, running it backwards and forwards in contact with the running surface causes the cutter edges to be honed.
