Claims8
A sharpener for a rotary action electric razor with a comb having an annular, flat-bottomed, slotted trough and a blade having a plurality of spaced heads rotating in the trough, the sharpener comprising a flexible, normally flat annular disc receiveable in the trough flushly against its flat bottom and having a sharpening abrasive flat surface, the disc having a tab extending from an edge thereof and positionable at an angle to the plane of the disc and generally parallel to a side wall of the trough when the disc is received therein.
A method of sharpening a rotary action razor having a comb with an annular, flat-bottomed, slotted trough and a blade having a plurality of spaced blade heads rotating in the trough, the method comprising the separate operations of:
- a. inserting between the blade heads and the trough a flexible annular disc having an abrasive, flat surface lying against the inner flat-bottomed surface of the trough and having a tab arising from its inner periphery adjacent an inner wall of the trough and in the path of rotation of a blade head, and rotating the blade in the trough whereby the disc is caused to simultaneously rotate and sharpen the comb;
- b. inserting between the blade heads and the trough a flexible annular disc having an abrasive surface abutting the blade heads and having a tab arising from its outer periphery in non-obstructing relationship to the blade heads and in contact with the outer wall of the flat-bottomed trough, the disc remaining stationary in the trough, and rotating the blade heads against the abrasive surface within the trough to sharpen the blade.
