A personal care device is provided with a cutting unit comprising an external cutting member and an internal cutting member. A virtual skin plane is located on a side of the external cutting member facing away from the internal cutting member. The internal cutting member comprises cutting elements each having a first cutting edge. The external cutting member comprises hair-entry apertures each having a second cutting edge. In a starting position of cutting a hair situated in a cutting position in the hair-entry aperture and extending perpendicularly to the virtual skin plane, the first cutting edge is in contact with the hair in a first contact position, and the second cutting edge is in contact with the hair in a second contact position, wherein the first contact position is closer to the virtual skin plane than the second contact position.

A stationary blade for a blade set of an electrically operated hair cutting appliance includes first and second walls, where each wall has a first surface, a second surface facing away from the first surface, and a laterally extending leading edge having a plurality of laterally spaced apart longitudinally extending projections. The first surfaces of the first and second walls face each other, at least at their leading edges, while corresponding projections along the leading edges of the first and second walls are mutually connected at their tips to define a plurality of generally U-shaped teeth. The first surfaces of the first and second walls are separated to define a laterally extending guide slot for insertion of a movable blade of the blade set between them. The projections of the first wall have an average thickness that is less than an average thickness of the projections of the second wall.

A hair-cutting appliance comprising at least 19 hair-cutting units (10), each comprising a guard element (20) and a rotatably arranged hair-cutting element (15) having at least one hair-cutting edge (16), is provided. The hair-cutting units of the hair-cutting appliance are relatively small, a base of the guard element having a diameter in a range of 7 mm to 13 mm. In order to have a relatively small guard element (20) which is of robust and uncomplicated design, and which is capable of contributing to excellent hair-cutting results without causing skin irritation, it is proposed to let both an inner surface (35) and an outer surface (36) of an annular shaving track (30) of the guard element (20) have a conical shape relative to a central axis (21) of the guard element (20), in a similar slanting orientation relative to the central axis (21), in at least a hair-cutting portion of the shaving track (30).

A beard trimmer having a handle, a motor and a head portion. The head portion comprises at least a first long hair cutter unit for trimming hair that is provided with a first outer cutter and a first inner cutter.

A beard trimmer which has a handle, a motor and a removable head portion. The head portion has first long hair cutter unit for trimming the hair length that is provided with a non-foil type outer cutter and an inner cutter. A first comb unit is provided having comb elements located adjacent to multiple cutting slots of the outer cutter. One comb element is provided on each of the opposite sides of the outer cutter. Each comb element provided with a row of comb teeth and comb slots separating the comb teeth from another. Each of the comb teeth has a tooth skin contact surface which is located on an elevated upper level relative to a cutter skin contact surface of the outer cutter.

A beard trimmer which has a handle, a motor and a removable head portion. The head portion comprises at least a first long hair cutter unit for trimming the hair length that is provided with a first, non-foil type outer cutter and a first inner cutter.

A shaving apparatus, shaving head and/or at least one cutting unit for shaving both short and long hairs. The shaving apparatus, shaving head and/or at least one cutting unit includes an external cutting member and an internal cutting member movably arranged with respect to the external cutting member. A driver may be provided for moving the internal cutting member. The external cutting member is provided with a shaving section having two mutually connected lateral borders forming hair entry apertures. The internal cutting member is provided with cutting elements having cutting edges for cooperation with cutting edges of the external cutting member. A number of the hair entry apertures are formed by two substantially flat lamellae of the external cutting member which have free ends positioned between the borders of the shaving section.

A cutter unit (1) for a rotary shaver is formed by an outer cutting element or cap (2) which interacts with a rotating inner cutting element or cutter (4) to trap and cut hairs. The cap has an annular shaving track (8) of domed cross-section having slots (30) through which the hairs may protrude. The cutter has a convex upper face (22) to engage the shaving track and a concave forward face (26).

A stationary blade for a blade set of an electrically operated hair cutting appliance includes first and second walls, where each wall has a first surface, a second surface facing away from the first surface, and a laterally extending leading edge having a plurality of laterally spaced apart longitudinally extending projections. The first surfaces of the first and second walls face each other, at least at their leading edges, while corresponding projections along the leading edges of the first and second walls are mutually connected at their tips to define a plurality of generally U-shaped teeth. The first surfaces of the first and second walls are separated to define a laterally extending guide slot for insertion of a movable blade of the blade set between them. The projections of the first wall have an average thickness that is less than an average thickness of the projections of the second wall.

A rotary electric shaver includes a head connected to a blade setting base of a main body. The blade setting base has a setting part in which a plurality of blade units are disposed, and a blade frame that holds the setting part. An inner blade part of the blade unit has an inner blade member, and a base part joined to the inner blade member. An outer blade part of the blade unit has an annular outer blade member having a sliding contact surface and a plurality of slits formed in the circumferential direction, a disk-shaped cover, a ball, and a support. A part of the ball surrounded by the cover and the support protrudes from the cover.
