摘要： A razor blade is proposed. The razor blade may include a substrate having a substrate edge with a substrate tip formed at an end portion. The substrate may include a first facet extending from the substrate tip to one side, a second facet extending from the substrate tip to the other side, a third facet extending from the first facet, and a fourth facet extending from the second facet. A slope of the first facet and a slope of the second facet may be different from each other. A first horizontal line perpendicular to the first vertical line may pass through a first point, and a second horizontal line perpendicular to the first vertical line may pass through a second point. A difference between a first vertical distance and a second vertical distance may be 10 micrometers to 30 micrometers.

摘要： A razor blade is proposed. The razor blade may include a substrate that has a substrate tip formed at an end portion and includes a first substrate facet and a second substrate facet extending from the substrate tip to both sides. The razor blade may also include a coating that is joined to the substrate and has a coating tip formed at an end portion and includes a first coating facet and a second coating facet extending from the coating tip to both sides and corresponding to the first substrate facet and the second substrate facet, respectively. The substrate may further include a third substrate facet extending from one end of the first substrate facet. A line tangential to the first substrate facet and a line tangential to the third substrate facet may not be parallel to each other.

摘要： A shaving blade is proposed. The shaving blade includes a substrate having a cutting edge, a substrate tip, and a plurality of coating layers laminated on the substrate. A first thickness of the substrate is defined as a thickness measured at a first distance that is 8 micrometers from the substrate tip along a central axis. A second thickness of the substrate is defined as a thickness measured at a second distance that is 16 micrometers from the substrate tip along the central axis. A third thickness of the substrate is defined as a thickness measured at a third distance that is 32 micrometers from the substrate tip along the central axis. The plurality of coating layers include a first coating layer, a second coating layer, and a third coating layer, and contain one or more of chromium boride (CrB), chromium carbide (CrC), or Diamondlike carbon (DLC).

摘要： The present invention relates to a skin treatment sheet comprising a substrate with a plurality of apertures wherein the sheet has a first surface and an opposing second surface. The apertures have a first and second inner perimeter and a cutting edge along at least a portion of the first inner perimeter. The skin treatment sheet has a stability ST which is the ratio of the average cross-sectional substrate area Ax and the total aperture area A1. Moreover, the present invention also relates to a skin treatment device comprising this skin treatment sheet.

摘要： The invention relates to a blade unit (01) for a wet razor comprising a support frame (02), which has an inner face and an outer face oriented towards a shaving plane and in which a plurality of elongate blades (03) are arranged. The support frame (02) has two opposing side portions (07) which extend transversely with respect to the cutting edges (04) of the blades (03). A plurality of parallel supports (09) extend between the side portions (07), between which supports an open space (11) remains. Each of the blades (03) is mounted to the inner face of the head portion (12) of one of the supports (09) so that the cutting edge (04) lies in the open space (11). The invention also relates to a wet razor comprising a handle and a blade unit (01) fastened directly or indirectly thereto.

摘要： A shaving implement comprises a cutting portion and an end portion. Further, the cutting portion transitions between a straight configuration and a bent configuration based on an application of an external force on the cutting portion. forming a bend in the cutting portion characterized by a curvature and a direction. Further, transitioning the cutting portion from the configuration to the straight configuration comprises removing the bend. Further, the cutting portion is not transitionable between the straight configuration and the bent configuration without the application of the external force. Further, the cutting portion comprises a blade slot for receiving a blade. Further, the cutting portion curves the blade in a blade shape based on the forming of the bend. Further, the end portion removably holds the cutting portion.
