The haircutter according to the invention serves for trimming and styling hair and comprises a grip and a blade head connected with the grip. A working section is disposed at one longitudinal face of the blade head and recessed from an alignment line of the longitudinal face. A haircutting blade having at least one cutting edge is accommodated in the blade head and disposed so as to expose at least part of its cutting edge in the working section and to not protrude beyond the alignment line. The blade head comprises a guiding device having at least one placing surface for the hair to be trimmed so that the hair to be trimmed lies at a defined angle to the cutting edge as the placing surface is placed against the hair.

A razor is provided comprising a razor cartridge fitted with at least one razor blade having a cutting edge which is curved, when viewed in plan, and arced, when viewed from the front, the razor blade being angled relative to a surface to be shaved, the curved cutting edge defining an arc with two ends and a midpoint. The orientation of the razor cartridge is movable between a first position, in the case of a flat surface to be shaved, in which the two ends and the midpoint of the arc are on the same plane to define a flat shaving profile; a second position, in the case of a convex surface to be shaved, in which the midpoint of the arc is lifted relative to the two ends of the arc, to define a convex shaving profile; and a third position, in the case of a concave surface to be shaved, in which the midpoint of the arc is lowered relative to the two ends of the arc, to define a concave shaving profile.

A shaving device comprising a head assembly including a support member having at least one support member magnet and a blade cartridge having at least one face with at least one razor blade and configured to be rotatably coupled to the support member about a pivot axis. The blade cartridge includes at least one blade cartridge magnet having a pole aligned with a pole of the support member magnet to generate a magnetic force that urges the blade cartridge about the pivot axis towards an initial starting position (ISP), wherein the blade cartridge is further configured to rotate about the pivot axis away from the ISP upon application of an external force sufficient to overcome the magnetic force between the support member magnet and the blade cartridge magnet.

The present invention relates to a unitary razor blade and to a shaving razor using the same, and more particularly, to a razor blade which is shaped into a geometrical structure so as to achieve the maximized strength thereof. The razor blade according to the present invention comprises: an edge portion having a curved cutting edge; a connection portion which extends from the edge portion and which is formed into a curve; and a support portion extending from the edge portion to support the edge portion and the connection portion, where the edge portion, the connection portion and the support portion are combined into a single body.

A shaving system includes a blade head frame and blades. The blade head frame is provided with a front side wall located in front of the blades, the blades extend in a left-right direction of the blade head frame, and cutting edges of the blades face the front side wall of the blade head frame. The front side wall of the blade head frame is provided with a protective member, and a supporting sidewall between the protective member and the blades, an upper surface of the protective member is 0.05-0.80 mm higher than an upper surface of the supporting sidewall, and the upper surface of the supporting sidewall is 0.01-0.32 mm higher than the cutting edge of the blade adjacent to the supporting sidewall, so as to effectively reduce the skin bulging at the protective member and the blades during shaving, thereby ensuring shaving comfort.
