The present invention relates to a cutting blade having a blade body with a first material joined to a second material, a first face, a second face opposed to the first face, and a cutting edge, where the first face includes a first surface, and the second face includes a primary bevel having a convex or straight cross-sectional shape and a secondary bevel having a concave cross-sectional shape with a line connecting the two bevels, the primary bevel extending from the cutting edge to the line, where cutting edge and primary bevel are shaped in the second material. A first wedge angle θ.sub.1 between the first surface and the primary bevel or the tangent of the primary bevel through the cutting edge is greater than a second wedge angle θ.sub.2 between the first surface and the tangent of the secondary bevel. A hair removal device includes this cutting blade.

A razor blade head for shaving, comprising a razor blade element, a bracket mounted to the razor blade element and a manual control element configured to enable a user to apply force from a side of the bracket opposite to the razor blade element, the force transferred from the manual control element to the razor blade element via the bracket, wherein the bracket is configured to define an opening between the manual control element and the razor blade element.

Razor having a hair-cutting fiber having a hair-cutting section attached to a support in such a position relative to a skin engaging surface that the hair-cutting section is exposed to a user's skin for cutting through hairs when the skin engaging surface is in contact with the skin and moved over the skin. The hair-cutting section has a fiber diameter smaller than or equal to 7 μm and is made from a fiber material having a tensile strength larger than or equal to 5 GPa. A shaving method using such a razor is also described.

The present invention relates to a cutting blade having a first face, a second face opposed to the first face and different from the first face as well as a cutting edge at the intersection of the first face and the second face. The first face comprises a first surface and a primary bevel with a first wedge angle θ.sub.1 between the first surface and the primary bevel. The second face comprises a secondary bevel and a tertiary bevel with a second wedge angle θ.sub.2 between the first surface on the first face and the secondary bevel and a third wedge angle θ.sub.3 between the first surface on the first face and the tertiary bevel, where θ.sub.1>θ.sub.2 and θ.sub.2<θ.sub.3. Moreover, the present invention relates to a hair removal device comprising this cutting blade.

The present invention is directed to a shaving device including a housing with a skin contacting surface and at least one cutting blade mounted in the housing, wherein the at least one cutting blade has an asymmetric cross-sectional shape with a first face, a second face opposed to the first face as well as a cutting edge at the intersection of the first face and the second face. The blade is mounted in the housing such that the clearance angle α between the skin contacting surface and the primary bevel of the first face or the secondary bevel of the second face is ≤11°, the effective cutting angle ε between the skin contacting surface and the bisecting line of the first wedge angle θ.sub.1 between the first surface and the primary bevel is ≥10° and θ.sub.1>second wedge angle θ.sub.2 between the first surface and secondary bevel.

A razor head comprises a frame. The frame comprises a leading longitudinal member and a trailing longitudinal member. The razor head further comprises a plurality of substantially parallel cutting members disposed between the leading longitudinal member and the trailing longitudinal member, and a cutting member support arranged in the frame, wherein the cutting member support is coupled to the plurality of cutting members. The cutting member support is configured to displace at least one cutting member of the plurality of cutting members from a default position to at least one predetermined deviating position based on an external stimulus.
