A shaver (10) includes a razor blade (20a, 20b) that cuts hairs coming into contact therewith. A heating element (26a, 26b) is bonded to the razor blade (20a, 20b). The heating element (26a, 26b) generates heat when an electric current is passed therethrough, the generated heat being directly supplied to the razor blade (20a, 20b). A battery (32) generates electric current, and electrical conductors (28, 30, 50, 52) route electric current generated by the battery (32) to the heating element (26a, 26b). A handle (16) is adapted to be held by a user for manipulation of the shaver (10). Suitably, the handle (16) houses the battery (32), and a head (12) houses the razor blade (20a, 20b) and heating element (26a, 26b) bonded thereto, the head (12) being selectively attachable to and detachable from the handle (16).

An electrically powered slotted rotary shaver which provides the clean, close shave of a hand-held razor combined with the safety, comfort and convenience of an electric shaver. The slotted rotary shaver comprises a body portion and a shaving portion. The head portion is provided with one or more shaving head assemblies having fixed upper grids and lower rotary grids. The upper grids are positioned upon a shaft extending from motor positioned within the body portion of the shaver. The upper grids are advantageously separated into four pie-shaped quadrants held together at the center by a pivot point, and comprise a plurality of apertures disposed over the high surface active cutting area of the upper grid through which hair protrudes when the head portion of the shaver is placed against a user's skin. The edges of each quadrant of the upper rotary grid also include sharpened blades which are arranged diametrically opposite one another to define slots through which long and/or curly hair, as well as previously cut stubble protrudes when the head portion of the shaver is placed against the user's skin. The lower rotary grid which includes openings thereon, is disposed on motor shaft below the upper grid and is planerized through opposite magnetized polarity such that when the shaver is activated, the lower rotary grids spin at high speeds in a continually reversing clockwise and counterclockwise directions upon the motor shaft to create a scissoring action which cuts the hair which has protruded through the apertures and slot of the upper rotary grid and the openings of the lower rotary grid when the shaving portion of the shaver is placed against a user's face.

Electric shaver provided with a handle and a shaver head including at least one drivable cutter element, wherein said shaver head is connected to said handle by means of a support structure providing for a swivel and/or tilting axis about which said shaver head may swivel or tilt relative to said handle, wherein said support structure includes a pair of link arms forming a four-joint linkage with each link arm having a head joint connected to a shaver head part and a handle joint connected to the handle or a base part connected thereto.
