Abstract
A dry shaver is capable of being depressed equally at different positions but with differing contact pressures between outer and inner cutters. The shaver has a housing having a motor and inner and outer cutters at its upper end. The inner cutter is driven by the motor to move in shearing engagement with the outer cutter for shaving hairs. The inner cutter is urged upwardly by a bias spring to develop a contact pressure against the outer cutter. The outer cutter is carried by a cutter holder movably supported to a head frame mounted on top of the housing. The shaver has a height adjust mechanism for adjusting the height of the head frame relative to the housing between a high position and a low position while compressing the spring differently to vary the contact pressure, and for allowing the cutter holder to be depressed relative to the head frame from each of the height and low positions.
