The sharpener is positioned between the shear plate and blade and includes a thin sheet having an abrasive material thereon suitable for sharpening the blade or for engagement with and honing the inner surface of the shear plate. In one embodiment, the thin sheet is of size and shape that it is held by the ends of the shaver housing when sharpening the blade. In another embodiment, means are included on the thin sheet for holding the thin sheet on and for movement with the cutting blade to recondition or hone the head. In either embodiment, operation of the shaver's blade drive motor will drive the cutter blade while it either engages the abrasive surface as in the first embodiment or in the second embodiment moves the abrasive surface over the head.
