ABSTRACT:
A dry shaver has a reciprocating inner cutter (9) co-operating with an arched flexible foil (8) of which the foil is fastened at its edges to a base member (7) and the inner cutter is pressed against the foil by springs which act between the inner cutter and the base member. The above mentioned parts form a cutting unit which is detachably mounted on the casing through the intermediary of spring loaded retainers (18) which permit movement of the cutting unit towards and away from the casing. The resilient force applied through the retainer is substantially less than that of the springs acting on the inner cutter, so as to permit displacement of the cutting unit under the forces encountered during shaving without deflection of the inner cutter springs.
