A cutting head (18) for a hair cutting appliance (10) comprises a blade set (20) including a stationary blade (36) and a cutter blade (38). The stationary blade and the cutter blade comprise at least one toothed leading edge (22,24) jointly defined by respective teeth (62,64) thereof that extend in a longitudinal direction (X). The stationary blade further comprises a front face (58), at the teeth (62) thereof, arranged to face a user's skin, when in operation. A skin protector (76) couples to a housing portion (32) of the cutting head, wherein the skin protector at least partially covers the front face (58) and is arranged to contact the skin, when in operation. The skin protector is movable between a first state and a second state with respect to the blade set (20) and includes an advanced position in the first state and a retracted position in the second state.

A slit blade block is provided with a slit outer blade, a comb component, and an outer blade connector to which the slit outer blade is fixed. The comb component is sandwiched between and held by the slit outer blade and the outer blade connector when the slit outer blade is fixed to the slit connector.

A shaver head comprising a blade assembly having one or more blades for cutting hair in a shaving direction; a skin adaptor extending from an outer periphery of said blade assembly and having a skin adaptor surface configured to be in contact with a shaving surface; a coil assembly, the coil assembly being configured to be transitioned between an active state and an inactive state and to generate an electromagnetic field in the active state. The electromagnetic field can be configured to cause pili muscles in the shaving surface to contract in order to expose hair of the shaving surface so that the hair is cut by the blades of the blade assembly.

Adjustment device (10) for a hair cutting device (20), the hair cutting device (20) having a device housing (22) and a cutting set (24) connected to the device housing (22), the cutting set (24) of a shear blade (26), which contains shear blade tips (30), and a shaving comb (28) connected therewith, which contains comb tips (32), wherein the shaving comb (28) is connected to the shear blade (26) and thus also releasably connectable to the hair cutting device (20). The adjustment device (10) is dimensioned in such a way that it can receive and hold the shaving comb (28) so that after loosening the connecting elements (62), the shaving comb (28) together with the adjustment device (10) is movable relative to the device housing (22) so that a distance between the shear blade tips (30) and the comb tips (32) can be set.

An electric shaver includes a main body, an outer blade that is held by the main body in a state where a surface of the outer blade is exposed, an inner blade that is disposed inside the outer blade so as to be movable relative to the outer blade, and a rotator that has a rotating body disposed in the main body so as to extend in a moving direction of the inner blade, and a supporter disposed in the main body so as to rotatably support the rotating body. The rotator has an elastic body which enables the rotating body to rotate in a state where the rotating body is in contact with a skin, and which restrains the rotating body from vibrating in a state where the rotating body is not in contact with the skin.

A method of manufacturing a component from a high-strength blank metal strip or sheet (MS) having a tensile strength of at least 850 MPa. The method comprises reducing the thickness (T) of the strip or sheet (MS) in a folding section (FS) so that a shaped section (SS) having a predetermined shape is obtained in at least a part of the folding section (FS). The strip or sheet (MS) is then folded along the shaped section (SS), so that a surface of a first section (1S) becomes arranged adjacent and parallel to a surface a the second section (2S) of the metal strip (MS). Finally, the first and second sections (1S,2S) are joined, so that the strip or sheet (MS) remains folded. With this method, it is possible to use high-strength steel, e.g. AISI 301 stainless steel, and still fold a thin strip or sheet (MS) without undesired cracks in the folding section. For example, the invention is applicable for manufacturing of plate-shaped hair-pulling elements (HPE) for a cutting unit (CU) of a shaving apparatus.
