The invention relates to a shaving head (1) having at least two cutting members, the cutting edge (7)of at least one of the cutting members (5) being situated at a side, remote from the other cutting member (9), of an imaginary center plane (41) of the carrier (31) of the relevant cutting member, and having a tip angle (α1)enclosed by a main side face (37) and a facet surface (43) of the carrier (31). In this manner, the cutting edge of the relevant cutting member has a tip angle (α1) which is asymmetrical relative to the center plane of the carrier. As a result, a space (57), which is present between the carriers (31, 33) of the two cutting members, is divergent, viewed from the skin contact surface (29), and the risk of said space becoming clogged by cut hairs and shaving foam is considerably reduced.
A shaving head comprising at least a first cutting member and a second cutting member which, viewed in a shaving direction of the shaving head, is arranged behind and spaced apart from the first cutting member to create an interspace between the first and second cutting members, said cutting members each comprising a plate-shaped carrier having mutually parallel first and second main side faces, the first main side face of the first cutting member facing away from the second cutting member and the second main side face of the first cutting member facing the second cutting member, the first and second cutting members provided with a substantially straight cutting edge extending substantially in a skin contact surface with which, in operation, the shaving head bears against the skin to be shaved, and a cutting angle present between the second cutting member and the skin contact surface being equal to or larger than a cutting angle present between the first cutting member and the skin contact surface, the cutting edge of at least the first cutting member being situated on a side, facing away from the second cutting member, of an imaginary center plane of the carrier of the first cutting member, said imaginary center plane extending between the first and second main side faces of the carrier, characterized in that the interspace between the first and second cutting members, as viewed from the skin contact surface, is divergent.
