The hair clipping device (10) further comprises an end stop element (74) which is configured to prevent a movement of the comb attachment (12) towards the cutting assembly (16) during the retraction movement when a minimal distance between the comb attachment (12) and the cutting assembly (16) is reached by contacting the comb support element (45). The end stop element (74) is further configured to cause a coupling of the adjustment unit (58) with one of the stationary cutting blade (32) and the moveable cutting blade (34) if the retraction movement of the adjustment unit (58) is continued after the minimal distance between the comb attachment (12) and the cutting assembly (16) is reached after a contact of the end stop element (74) with the comb support element (45). Said coupling enables an adjustment of the position of the moveable cutting blade (34) relative to the stationary cutting blade (32) along a second axis (56) transverse to the first axis (40) by means of the adjustment unit (58).

The present disclosure relates to a method of forming a sheet-metal based double-walled stationary blade (24) for a hair cutting appliance (10), the method comprising: providing a first pre-product layer (70), providing a second pre-product layer (72) which is separate from the first pre-product layer (70), providing a guide slot (44) for a cutter (26), and bonding the first pre-product layer (70) and the second pre-product layer (72) to one another such that the pre-product layers (70, 72) are arranged to jointly receive a to-be-mounted cutter (26), wherein the first pre-product layer (70) and the second pre-product layer (72), in the bonded state, are at least partially offset from one another to provide a defined mating clearance fit for the to-be-mounted cutter (26), wherein the pre-product layers (70, 72) are bonded to one another at their longitudinal ends such that stationary blade teeth (54) are partially formed by the first pre-product layer (70) and partially formed by the second pre-product layer (72), and wherein tips (56) of the stationary blade teeth (54) are arranged adjacent to a transition zone (84) between the pre-product layers (70, 72). The present disclosure further relates to a cutting appliance and to a blade set (22) for such an appliance.

An inner blade of a rotary electric shaver decreases a rake angle and increases an erecting angle in a small blade, which can prevent remaining hair from appearing on one end side in a cross section of hair, and which can prevent poor shaving performance and increased sliding resistance against an outer blade. An inner blade of a rotary electric shaver includes an outer blade whose upper surface functions as an annular shaving surface having multiple hair inlets, and the inner blade having a plurality of small blades which rotate while coming into sliding contact with a lower surface of the outer blade. The small blade is formed by erecting a portion of a metal plate so that an angle of a front side in a rotation direction with respect to a plate surface of the metal plate becomes an acute angle, the front side in the rotation direction has a concave portion having a shape hollowed toward a lower end portion from an upper end surface which comes into sliding contact with the outer blade, and an upper end edge defined by the upper end surface and the concave portion functions as a blade edge.

A detachable floating shaver includes a head, a casing having a third through hole, a main housing, a first floating member, and a second floating member. Through the connection and positioning relationship between the two parent and child pivot portions, that is, the first floating member and the second floating member, the head can achieve a cross rotation relative to the main housing. The second floating member has a connecting member; through the detachable connection between the second floating member and the connecting member, the head of the shaver is detachably connected, which is convenient for replacement, cleaning and maintenance and is more practical. The shaver can achieve 360 rotation through two parent and child pivot portions and two elastic sleeves, and the effect of floating contact of the shaver with the user's face is good.

A razor blade cartridge having at least one razor blade and a housing made from a polymer material and having an outer surface where at least part of the outer surface of the housing is coated with a hydrophilic material, and where the outer surface of the housing includes undulations on at least a portion of the coated part.

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.
