Abstract: An electric dry shaver comprising a cutter mounted for arcuate oscillation about an axis to effect a shaving action, a driver secured to said cutter for arcuate oscillation about said axis, a trimmer element mounted for linear reciprocation parallel to said cutter axis to effect a hair trimming action, and a coupling mechanism selectively engageable between said driver and said trimmer element to convert arcuate driver oscillation into linear trimmer reciprocation via the intermediary of a cranked lever mounted for pivotal oscillation about an axis perpendicular to both the cutter axis and the trimmer element.
