A shaving apparatus (1000) is disclosed in which a rotary cutter (1300) and a fixed blade (350) are used to shear a user's hairs therebetween during a shaving process. Various advancements are disclosed herein, including without limitation accurate positioning of the fixed blade in the head (200A) relative to the contact apex of the rotary cutter, bi-directional rotation of the rotary cutter, a cover-blade assembly for detachable coupling and decoupling from a base component of the head, the use of contact rollers on the head to treat and/or prep the skin and/or hairs for shearing, and a rotary cutter configured to pinch, pull and shear hairs.

One or more implementation disclosed herein provides razor assemblies that allow a user to have a less than smooth shave by changing the distance between razor blades and a razor blade guard. The distance between the razor blade(s) and the guard may be increased or decreased using a movable knob mechanism, a rotatable dial mechanism, a movable razor assembly and housing mechanism, a rotatable threaded handle, one or more slider mechanisms, a rotating blade mechanism, etc.

A shaving apparatus in which a rotary cutter and a fixed blade are used to shear a user's hairs therebetween during a shaving process. Rotation of the rotary cutter is driven by an electric motor. In certain embodiments, the rotary cutter comprises a cutting tube that comprises a plurality of apertures that are defined by cutting edges which form a closed-geometry. In other embodiments, a lubricating element is coupled to the rotary cutter. In further embodiments, the apertures are arranged in a pattern to control the number and selection of apertures that are capable of being active to shear hairs at any one time. In even further embodiments, the fixed blade is integrally formed with the housing of the head; the housing is formed by a plurality of flat plate segments; the rotary cutter is formed by a plurality of stacked flat plate segments; and/or the fixed blade can reciprocate.

A multi-cutting element shaving device is disclosed. The device comprises a handle and a head portion comprising at least two cutting assemblies, which are mounted in parallel, to one another on a frame of the head portion. The cutting assemblies include each a cylindrical screen and a blade housed in the cylindrical screen. Each of said cylindrical screens is rotatable about a respective longitudinal symmetry axis thereof, and the rotation of each cylindrical screens is manually effected by translating the head portion along a surface with the cylindrical screen contacting the surface so that substantially no sliding, of the cylindrical screens occurs as the head portion is translated against the surface. The head portion mounting angle relative to the handle is changeable during use of the shaving device such that both cylindrical screens are simultaneously maintained in contact with the surface, which is being shaved.

A scratch-resistant razor head includes a head frame and a razor blade including a support bar having an inclined platform and a blade portion mounted on the inclined platform. An angle between a cutting edge of the blade portion and a front end face of the inclined platform is greater than 0 degree and less than or equal to 0.5 degree; two resilient legs are respectively extended from the left and right frame walls and toward each other, each resilient leg includes an resilient inclined leg and a receiving leg extended from the inclined leg along the direction of the first axis, a convex point is formed by projecting from a top surface of the receiving leg, and the convex point is contacted with the inclined platform. A razor with such a razor head is also provided.

A razor head having trimming unit includes a framework, at least one razor blade, a trimming unit, and a lubricating strip. The framework includes a front part, a rear part and two side parts. The trimming unit is arranged along a lengthwise direction of the framework and configured on the two side parts. The trimming unit and the rear part are configured side by side and define a receiving groove together. A side wall of the rear part for defining the receiving groove has a first contact portion extended into the receiving groove, and a side wall of the trimming unit for defining the receiving groove has a second contact portion extended into the receiving groove. The second contact portion corresponds to the first contact portion so that the first and the second contact portions clamp the lubricating strip in the receiving groove together.
