Abstract
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.

Haircutter for trimming and styling hair, comprising:
- a grip and a blade head with a haircutting blade defining a plane and having a first cutting edge in a fixed position in the blade head, the blade head being connected with the grip,
- the blade head comprising two blade head members adapted to interlock with each other and contain the haircutting blade between themselves, the blade head members each comprising a side face opposed to the side face of the other blade head member,
- the blade head members when interlocked defining a first longitudinal face at a juncture of edges of the blade head members, wherein the first longitudinal face intersects the plane of the haircutting blade adjacent the first cutting edge of the haircutting blade,
- the first longitudinal face of the blade head defining a first alignment line, the first longitudinal face having only one working section disposed thereat which is configured as a recess from the first alignment line of the longitudinal face and wherein the blade head members accommodate the haircutting blade so that the first cutting edge of the haircutting blade is at least partially exposed in the working section disposed in the first longitudinal face and does not protrude beyond the first alignment line,
- each of the side faces of the blade head members comprises a guiding device integrally formed in the side face of the blade head member, the guiding devices each having a first placing surface for the hair to be trimmed that comprises at least one first placing section and following behind and adjacent to the first placing section a second placing section transverse to a longitudinal axis of the blade head, and wherein the first placing section is disposed closer to the exposed cutting edge of the haircutting blade in the working section disposed in the first longitudinal face than is the second placing section, the first placing section being disposed adjacent to and surrounding at least a portion of the working section disposed in the first longitudinal face, the first and the second placing section each having an acute angle with respect to the plane of the haircutting blade, the first placing section has a larger acute angle with respect to the plane of the haircutting blade than does the second placing section and the first placing surface is at least partially disposed at an angle to the plane of the haircutting blade when the haircutting blade is oriented in the blade head so that the hair to be trimmed lies at a defined angle to the cutting edge as the first placing surface is placed against the hair.

- wherein the blade head comprises on at least on one side of the blade head at least one third placing section next to and extending along a longitudinal direction parallel to the longitudinal axis of the blade head away from the working section, and
- wherein the blade head comprises, on the at least one side of the blade head, an elevation in the blade head extending substantially in a diagonal, and the at least one third placing section on the at least one side of the blade head extends between the elevation and a section of the longitudinal face of the blade head.
