At least some of the webs are provided with a concave clearance formed between a side surface and the lower surface forming an edge with the side surface. Further, a shaver having such an outer blade and a method for producing an outer blade using etching are disclosed.

A shaving and grooming apparatus includes a handle and a cartridge attached to the handle. A plurality of upper blades are positioned in the cartridge, where at least some of the plurality of upper blades include curved tips with a curvature that sufficient to prevent the curved tips from contact a cutting surface during use. A plurality of lower blades is positioned adjacent to the plurality of upper blades in the cartridge, where at least some of the plurality of lower blades comprises curved tips with a curvature that sufficient to prevent the curved tips from contact a cutting surface during cutting. At least one of the plurality of upper and the plurality of lower blades has a thickness and flexibility that results in deflection during cutting that increases effectiveness of cutting action. A drive motor moves the plurality of upper blades relative to the plurality of lower blades.

A trimmer includes a blade assembly including a stationary blade and a movable blade. Each of the stationary blade and the movable blade includes blade teeth. The stationary blade includes a first transverse edge portion, a second transverse edge portion, and a middle portion. The first transverse edge portion includes a first upper surface extending from a first edge to the upper surface. The second transverse edge portion includes a second upper surface extending from a second edge to the upper surface. The first transverse edge portion and the second transverse edge portion are beveled from the middle portion to the respective edges of the stationary blade. The stationary blade is symmetric about a midline of the middle portion. In some embodiments, the trimmer includes a toothed blade guard.

A stationary blade for a blade set of a hair cutting appliance includes a top wall, a bottom wall, and a guide slot formed between the top and bottom walls to accommodate a movable blade. The stationary blade further includes a plurality of stationary blade teeth each having a frontal end. The top and bottom walls are mutually joined at the frontal ends, where the top and bottom walls are, at least at the frontal ends, made from sheet metal material. Further, at the frontal ends, two or more sheet metal folded edges are present.

The present disclosure relates to a method of manufacturing a stationary blade (102) and to a stationary blade (102), the method comprising providing a metal component (106), involving applying a first bending procedure, thereby forming a top wall (112) and two legs (114, 116) at opposite ends of the top wall (112) that are spaced away from one another in a longitudinal direction, wherein, subsequent to the bending procedure, each of the two legs (114, 116) is arranged at a first angle (α) with respect to the top wall (112), and wherein two bending edges (152, 154) are formed between the top wall (112) and the two legs (114, 116), providing a support insert (108) having a longitudinal extension (l.sub.s) that is at least slightly greater than a receiving space (l.sub.b) between the two bending edges (152, 154), joining the metal component (106) and the support insert (108), wherein the metal component (106) is at least slightly pretensioned due to the longitudinal extension (l.sub.s) of the support insert (108), and applying a second bending procedure to the metal component (106), comprising further bending the two legs (114, 116), thereby arranging each of the two legs (114, 116) at a second angle (*) with respect to the top wall (112) that is smaller than the first angle (α).

The present invention relates to a cutter system for an electric shaver and/or trimmer, comprising a pair of comb-like cutting elements each with at least one row of cutting teeth and movable relative to each other, wherein one of said cutting elements has thickened and/or rounded tooth tips overhanging the tooth tips of the other cutting element wherein said cutting elements each include two rows of cooperating cutting teeth which are different from each other in terms of shape and/or size and/or position of said overhanging tooth tips.

Provided is a cutting assembly (100) for cutting hairs on skin. The cutting assembly comprises a guard plate (102) for contacting the skin. The guard plate has a first toothed edge (104A) which extends along an axis. The first toothed edge comprises guard teeth (106A). The cutting assembly further comprises a cutter plate (108) which is disposed on the guard plate. The cutter plate is slidable relative to the guard plate in directions parallel with the axis. The cutter plate comprises a second toothed edge (110A) extending parallel with the axis. The second toothed edge comprises cutting teeth (112A). The cutter plate and the guard plate are aligned such that the hairs are cut by the cutting teeth against the guard teeth when the cutter plate slides. The cutting teeth each include a cutting portion (114A) and a tip (116A). The tip is outwardly enlarged relative to the cutting portion in at least one direction parallel with the axis. The minimum space between adjacent tips is less than the minimum space between adjacent guard teeth. The tip thereby maintains overlap with at least one of the guard teeth during sliding of the cutter plate relative to the guard plate. Further provided is a trimmer including the cutting assembly.

The present invention relates to cutting body hair such as beard stubbles of multidays' beard. More particularly, the present invention relates to a cutter system for an electric shaver and/or trimmer, comprising a pair of cooperating cutting elements with two rows of comb-like cutting teeth at opposite edges thereof.

The present invention relates to a cutter system for an electric shaver and trimmer, comprising a pair of cooperating cutting elements with two rows of comb-like cutting teeth at opposite edges thereof and cutting perforations between said rows of comb-like cutting teeth, wherein said cutting elements are movably supported relative to each other by a support structure. The cutting perforations may be arranged in two separated elongated fields of perforations which are separated from each other by an elongated unperforated center section of an outer one of said cutting elements defining a skin contact surface, and which include each at least two rows of perforations extending along the rows of comb-like cutting teeth.
