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.

The present disclosure generally relates to instruments for neurotologic surgical procedures, and more particularly, instruments for shearing ear canal hairs having combined shearing, illumination, and vacuum functions. In certain embodiments, the instruments may further facilitate visualization of the ear canal during the shearing of ear canal hairs.

An electrical appliance for performing a cutting action on hairs present on an area of skin (7) comprises at least one assembly of a driven internal cutting member (5) for cutting off the hairs and an external cutting member (6) which serves for contacting the area of skin (7) and also for covering and contacting the internal cutting member (5). The cutting members (5, 6) are designed such that friction between them is related to their condition of wear in a predetermined way. Information relating to an actual condition of wear of the cutting members (5, 6) is determined by measuring a parameter related to the friction between the cutting members (5, 6) and processing the parameter, and such information is indicated to a user of the appliance.

The present invention relates to a beard trimmer having one or more rotary heads (1), said rotary cutting heads having a moving blade (2) and a fixed blade (3), each head being surrounded by a crown-shaped comb (4), said comb being adjustable in height in order to adjust, in use, the distance between said blades and the skin, and thereby to adapt the cutting of the beard to the desired length, characterized in that the trimmer comprises a fixed bade having a shape characterized by: a tooth length L3 of 1 to 3 mm, preferably 1.5 to 2 mm; an opening angle between the teeth of 20 to 30?, preferably 22 to 28?, and more preferably 24 and 27?; a tooth width L2, at the end of the teeth, of 0.3 to 1 mm, preferably 0.4 to 0.9 mm.

A carrier is adapted for use in a shaving device and includes at least one pair (15) of a cutting element (8) and a hair lifting element (14). At least one of the elements (8, 14) of the pair (15) has a bent shape, wherein the bent element (8, 14) is provided with at least two bending lines (17, 18). The bent shape of the at least one of the elements (8, 14) is such that in a functional arrangement of the elements (8, 14) with respect to each other, edge portions (11, 16) of the elements (8, 14) are located at a distance with respect to each other. Thus, a space (22) is present between the elements (8, 14) at the side of their edge portions (11, 16), which can be used for receiving cut-off hair stubbles which might otherwise hinder a movement of the hair lifting element (14).

The invention relates to a rotary cutting unit (207) of a shaving head of a shaving device, which cutting unit comprises an external cutting member (211) and an internal cutting member (212). In interconnected condition, a holding force prevents the external and internal cutting members from moving apart. Said holding force is at least exerted by a first central portion (221) of the external cutting member upon a second central portion (222) of the internal cutting member, and/or vice versa. Said holding force may for example be provided by means of a snap connection or magnetic attraction between said first and second central portions. As compared to rotary cutting units of existing shaving heads, the invention meets various known desirable design requirements, while at the same time providing for manual removal and insertion of the internal cutting members in a very easy, comfortable and intuitive manner, and the structure to achieve all this being non-complex and compact.

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 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).
