| 20100154221 | Inclined razor blades sloping on X and/or Z axis - Multi blade razors having at least three blades for cutting the beard and/or unnecessary hairs. The razor is equipped with inclined and/or sloping blades. The inclination is a single inclination on one axis and possibly multiple inclinations in various axes. This allows implementation of a blade cut with consequent improvement of smoothness on the skin. The inclined blades are orientated on two axes to dissect the hair bringing the hair to the sharpened side without forcing the hair to be cut violently. The lifetime of the blade is improved, with a cutting capacity which is clearly superior to a razor extending perpendicular to a handle. The use of less than three inclined blades could be dangerous for the skin and might produce uncomfortable shaving, if utilized by non-professional barbers or untrained end-users. | 06-24-2010 |
| 20100299931 | STRENGTHENED RAZOR BLADE - A razor blade including a substrate with a cutting edge, the substrate includes a mixed nitride-substrate interregion disposed at or beneath a surface of the substrate, the mixed nitride-substrate interregion being substantially free of a compound layer. | 12-02-2010 |
| 20110146081 | RAZOR - The invention relates to hand-held portable cutting tools, in particular to safety razors. The razor comprises a holder with a handle and at least one pair of blades. The blades are arranged in the holder at an acute angle symmetrically to the razor longitudinal axis. A transverse jumper is made in the center of the holder. Said jumper fixes the position of blades. The setting angle of the blades ranges from 75 to 80°. In preferred variant, the razor comprises two or more pares of blades having different setting angles. Preferably, not more than four. It is reasonable to design the razor in such a way that the setting angle of each preceding pair of blades in the direction of the razor motion is greater than the setting angle of the next pair of blades. The invention makes it possible to increase the efficiency and ease of shaving and to reduce the production cost of the razor. | 06-23-2011 |
