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.

There is provided a rotary electric shaver which includes an external outer blade having a plurality of hair inlet holes on an annular shaving surface, an internal outer blade, a rotationally driven external inner blade having a plurality of small blades coming into sliding contact with a rear surface of the external outer blade, a rotationally driven internal inner blade, an external inner blade rest base, and an internal inner blade rest base. The external outer blade has a cylindrical guide ring formed on an inner peripheral side of an inner wall portion, and the external inner blade has a plurality of guides which come into sliding contact with an inner peripheral surface of the guide ring to perform radial alignment with respect to the external outer blade.

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.

The invention relates to a shaving unit (11) for use in a shaving device (1). The shaving unit comprises a supporting member (19, 21a, 21b, 21c) and at least two hair cutting units (7a, 7b, 7c) supported by the supporting member. Each hair cutting unit comprises an external cutting member (25a) with hair-entry openings (31) and an internal cutting member (27a) which is rotatable relative to the external cutting member about an axis of rotation (41) and which has a plurality of hair-cutting elements (35). The shaving unit further comprises a retaining structure (23a, 23b, 23c) which is releasably couplable to the supporting member and which is configured to retain the at least two hair cutting units in an operational position relative to the supporting member in an assembled condition of the shaving unit. The retaining structure comprises, for each respective hair cutting unit of the at least two hair cutting units, a separate retaining member (23a, 23b, 23c) which is releasably couplable to the supporting member and which is configured to separately retain the respective hair cutting unit in an operational position relative to the supporting member independently from any other of the at least two hair cutting units. The retaining structure further comprises, for each respective hair cutting unit of the at least two hair cutting units, a locking member (67) comprising at least one locking element (79a, 79b) which, in the assembled condition of the shaving unit, is biased by spring force towards the external cutting member of the respective hair cutting unit and engaged by an engagement element (87a, 87b) of the external cutting member to prevent rotation of the external cutting member about the axis of rotation. The locking member provided for the respective hair cutting unit is separately arranged from any other locking member, provided for any other of the at least two hair cutting units, and integrated with the separate retaining member provided for the respective hair cutting unit.

Provided is a method of producing an outer blade for a hair cutting device from a material including bars that each have a shape of a rectangular stick and are arranged at predetermined intervals. The material is placed on a base. Next, a first tool having a leading end that has a gradually increasing width in a direction away from the material is used to press at least one part of each of the bars in a direction from a counter base-side first face of each of the bars toward a base-side second face of each of the bars. An edge of the first face of each of the bars is caused to project widthwise and to move toward the second face to be farther from an intermediate part of the first face.

An electric razor for ergonomically and safely shaving contoured areas of the body, such as the armpit, pubic, and groin areas, without undue hand or wrist contortion. The razor features a cutting head of blades that are arranged to compositely form a spherical cap-shaped cutting surface.

An outer blade for a hair cutting device, the outer blade being mounted to an end of a main body of the hair cutting device, includes bars that each have a shape of a rectangular stick and are arranged at predetermined intervals. The outer blade also includes, at a skin-surface-contact-side first face of each of the bars, an agent holding part configured to hold an agent that is a substance having a predetermined effect on a skin surface, the agent holding part being a surrounded recess heading from the skin-surface-contact-side first face of the bar toward an inner-blade-side second face of the bar. Thus, the agent such as foam or gel can be held by the agent holding part at the skin-surface-side face of the outer blade, and friction can be reduced between the outer blade and the skin surface by the agent held by the agent holding part.

A shaver head assembly includes at least one cutting head component having a housing, an inner cutting blade mounted to the housing and configured and adapted to rotate about an axis and an outer cutting disc coaxially mounted about the axis. The outer cutting disc is configured to oscillate about the axis through positive and negative predetermined angular sectors of rotation, and is configured to cooperate with the inner cutting blade to cut hair.
