Abstract
An improved dry shaver has a shaving head mounting thereon a main shaving unit with a rounded shearing foil and at least one trimmer unit which is disposed in adjacent relation to the main shaving unit with its cutting edge directed away therefrom. A skin guide is provided outwardly of the trimmer unit in spaced relation thereto for contact with the skin of the user when manipulating the shaver across the skin. The skin guide has a contact end positioned at an elevation around an extension line connecting the apex of the shearing foil and the leading edge of the trimmer unit so that it can guide the shaving head along the skin while allowing the trimmer unit and the main shaving unit to be simultaneously in positive shearing contact with the skin. Consequently, during a single stroke of moving the shaver along the skin, the trimmer unit can serve to shear a long hair to a length sufficient to be subsequently cut by the main shaving unit, whereby enabling to cut a long hair close to the skin by the combined shearing operation in a continuous manner.
