Definitions

  • the present invention relates to a hairdressing knife for styling hair, having at least one handle and at least one knife head connected to the handle. At least one hairdressing blade having at least one cutting edge is accommodated in the knife head.
  • Cutting head hair with a barber's knife generally offers many advantages over cutting hair with scissors.
  • using a barber's knife requires a very precise position or guidance of the knife to the hair.
  • the angle at which the barber's knife is held to the hair while cutting is particularly important.
  • using a barber's knife therefore often requires intensive and professional instruction and a lot of practice and experience.
  • the hairdressing knife of the EN 10 2010 006 030 B4 The longitudinal axis of the blade is therefore positioned at an angle to the longitudinal axis of the hairdressing knife. This means that the cut is angled even when the hairdressing knife is held with its longitudinal axis straight to the hair.
  • a barber's knife for cutting beard hair is known, in which the handle and the blade head merge into one another in one piece.
  • several working sections are lined up next to one another, so that the cutting edge of the barber's blade is exposed there.
  • the blade head is angled in a wedge shape, so that there is a contact surface on both sides.
  • the sides run parallel to one another and also parallel to the barber's blade housed in the blade head.
  • the hairdressing knife according to the invention is used for styling hair, in particular head hair, and comprises at least one handle and at least one blade head connected to the handle. At least one working section is arranged on at least one long side of the blade head, which is set back from a line of alignment of the long side. At least one hairdressing blade with at least one cutting edge can be accommodated in the blade head.
  • the hairdressing blade can be arranged in the blade head in such a way that its cutting edge is at least partially exposed in the working section and does not protrude beyond the line of alignment or is set back from the line of alignment.
  • the blade head comprises at least one Guide device with at least one contact surface for the hair to be cut.
  • the contact surface is arranged at least in sections at an angle of between 16° and 26° to the plane of the hairdressing blade that can be accommodated in the cutter head. This ensures that the hair to be cut is at a defined angle to the cutting edge when the contact surface is placed against the hair.
  • the contact surface comprises at least a first contact section with an angle of 15° to 29° and at least one second contact section behind it, transverse to the cutter head longitudinal axis.
  • the second contact section has an angle of 12° to 18°.
  • the first contact section is arranged closer to the exposed cutting edge than the second contact section.
  • the first contact section has a larger angle than the second contact section.
  • the hairdressing knife comprises at least one hairdressing blade.
  • a particularly preferred hairdressing knife is equipped as follows: It is used for styling hair, in particular head hair, and comprises at least one handle and at least one knife head connected to the handle. At least one working section is arranged on at least one long side of the knife head, which is set back from a line of alignment of the long side. At least one hairdressing blade with at least one cutting edge is accommodated in the knife head. The hairdressing blade is arranged in the knife head in such a way that its cutting edge is at least partially exposed in the working section and does not protrude beyond the line of alignment or is set back from the line of alignment.
  • the knife head comprises at least one guide device with at least one contact surface for the hair to be cut.
  • the contact surface is at least partially at an angle of more than 12° and in particular less than 30° and preferably a maximum of 26° to the plane of the hairdressing blade accommodated in the knife head. This ensures that the hair to be cut is at a defined angle to the cutting edge when the contact surface is placed against the hair.
  • the hairdressing knife according to the invention offers many advantages.
  • a significant advantage is that the knife head has at least one guide device with at least one contact surface.
  • the contact surface aligns the hairdressing knife with the plane of the hairdressing blade at a particularly favorable angle to the hair.
  • the hairdressing knife simply needs to be placed against the hair with the contact surface in order to maintain a defined, optimal cutting angle. In this way, a significantly better hairdressing result can be achieved with the hairdressing knife according to the invention, even if the user has less practice or experience.
  • An angle of more than 12° is particularly advantageous, as this means the hair is cut optimally.
  • This type of angle means the hair is cut in such a way that more movement and, in particular, more volume are introduced into the hairstyle.
  • An angle of less than 30° is also particularly advantageous.
  • the angle range according to the invention effectively prevents a cut that is too flat, which would thin out the hair and make the hairstyle appear flat. It also reliably prevents a cut that is too blunt. It also reliably prevents splitting of the hair or other undesirable cutting results.
  • Another advantage is that the angle specified by the contact surface cannot be undercut, even if the hairdressing knife is operated incorrectly or is used without training.
  • the contact surface is at least in the area of the exposed cutting edge in the working section at an angle of more than 12° and in particular less than 30° and preferably at a maximum of 26° to the plane of the hairdressing blade accommodated in the cutter head. In the working section, it is particularly important to guide the hair at the correct angle.
  • the contact surface is arranged at least in the area of the exposed cutting edge in the working section at the angle provided according to the invention to the plane of the hairdressing blade accommodated in the cutter head.

  • the contact surface can be arranged at least in sections at an angle of less than 30°, 29°, 28°, 27°, 26°, 25°, 24°, 23° or 22°. Such angles have proven to be particularly advantageous in cutting and styling tests.

  • the at least one contact surface can also be designed separately from the knife head or from a knife head part.
  • the contact surface is provided by a wedge-shaped and/or curved shape of the cutter head. This allows the cutter head to be manufactured very precisely and at the same time cost-effectively, while reliably maintaining the required angle for the contact surface.

  • At least two contact surfaces are arranged on each side surface of the cutter head.
  • the contact surfaces of a side surface are assigned to different working sections, which are arranged in particular on opposite long sides of the cutter head.

This is particularly important with a wedge-shaped design of the knife head, since even a small increase in the width of the hairdressing blade causes the overall weight of the knife head to increase considerably. Due to the preferred angle of the contact surface to the plane of the hairdressing blade, a width of less than 20 mm for the hairdressing blade has proven to be particularly advantageous.
