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.
