Abstract

A device for shaving hairs growing from skin including a base portion having a grip, a shaving head which carries at least one cutting member having at least one cutting edge, and an actuator for effecting a periodical motion of the cutting member relative to the base portion to improve the cutting action of the cutting member. The shaving head is pivotable relative to the base portion about a pivot axis and the periodical motion of the cutting member is a periodical motion relative to the shaving head. The position and orientation of the geometrical path of the periodical motion of the cutting member relative to the skin is well-defined, so that the risk of skin irritations and skin injuries is considerably reduced.
