Abstract
A blade unit for a safety razor has a plurality of blades (7, 8, 9) with cutting edges (10, 11, 12) positioned between first guard and cap surfaces (26, 29) at an upper face of the unit, and a further blade (36) with a cutting edge (37) positioned between guard and cap surfaces (33, 34) at a rear face of the unit. The further blade at the rear face is intended for shaving skin areas, such as directly below the nostrils or in-front of the ears, to which access is restricted. A rinsing passage (35) connects a gap between the cutting edge (37) of the further blade (86) with an opening (38) at the bottom face of the blade unit for clearance of shaving debris and soap from the underside of the further blade (36) to the underside of the blade unit.
