Abstract

An electric shaver has a pivotally mounted longhair cutter unit that is pivoted outward into an operating position by motion of an operating switch of the shaver via an actuator that also causes the cutting blades of the longhair cutter unit to extend from the longhair cutter housing. Because the longhair cutter retracts into the longhair cutter housing when the longhair cutter unit is folded shut, the sharp edges of the blades are protected.
