A razor assembly is proposed. The assembly may include a razor cartridge including a blade housing configured to longitudinally accommodate at least one razor blade each having a cutting edge. The razor cartridge may include a cartridge top surface where the cutting edge is exposed and a cartridge bottom surface opposite to the cartridge top surface. The assembly may also include a razor handle connected to the razor cartridge, the razor handle including a light source unit configured to emit light from one side of the razor handle. The light emitted from the light source unit may be reflected by a reflective surface included in the razor cartridge and may be emitted to the outside at the cartridge top surface.

A shaver head comprising a blade assembly having one or more blades for cutting hair in a shaving direction; a skin adaptor extending from an outer periphery of said blade assembly and having a skin adaptor surface configured to be in contact with a shaving surface; a coil assembly, the coil assembly being configured to be transitioned between an active state and an inactive state and to generate an electromagnetic field in the active state. The electromagnetic field can be configured to cause pili muscles in the shaving surface to contract in order to expose hair of the shaving surface so that the hair is cut by the blades of the blade assembly.

An intelligent shaving system is disclosed herein including a system having a handle, at least one blade connected to the handle, a microcontroller attached to the handle, a wireless communication unit configured to send and receive data from microcontroller to an external device, a memory configured to store data applicable to the at least one blade, and one or more sensors configured to send sensory data from the one or more sensors to microcontroller. The one of the one or more sensors is a proximity sensor or a camera having image sensor configured to capture video and/or still images. The shaving system assists in determining blade attrition and provides indicators to assist in shaving techniques. The shaving system further may include at least one blade slightly curved to follow a tangent of the skin. The at least one blade may have a nanolattice structure.

The Tamian Sharpening Device (or T.S.D.) incorporates a novel razor blade sharpening technique that can rejuvenate metal razor blades of all types and extends their life. The T.S.D. utilizes a single wire coil and an Integrated Circuit (or I.C.) to generate an oscillating, electromagnetic force field (or E.M.F.), which polishes and sharpens the shaver's metal blades. When the E.M.F. is tuned to the shaver blade's natural resonant frequency, the sharpening process is amplified and enhanced. The T.S.D can be designed as a stand-alone sharpening unit or as new kinds of self-sharpening shavers both electric and handheld.

A shaving system including a handle, a cutting member, a sensor, a feedback indicator, and a microcontroller. The sensor is configured to detect a force exerted by the user. The feedback indicator includes an indicator display that is configured to generate a first indication in response to and representative of the force detected by the sensor. The microcontroller is configured to generate a first signal based on the detected force and send the first signal to the feedback indicator such that the feedback indicator generates the first indication during the shaving session to assist the user with shaving. The microcontroller is configured to send a second signal indicative of a change in force to the feedback indicator such that the feedback indicator generates a second indication including illumination in response to and representative of the change in force during the shaving session to assist the user with shaving.

The present disclosure relates to a smart straight razor. Particularly, the smart straight razor includes motor-driven assemblies coupled to a blade tray assembly that is controlled by a blade controller for safely loading, ejecting, and precisely adjusting exposure and/or tilt of a razor blade.
