With traditional razors, the cutting edge of a blade moves in the direction of the cut. A new shaving device, however, includes one or more blades that perform a vibrating motion perpendicular to the direction of the cut, and parallel to the blade’s edge; the hairs are cut by sawing, rather than cutting.
Because an additional blade movement is introduced (in the direction parallel to the blade), the sawing of the hair is easier than cutting. As sawing requires less energy than cutting, the act of shaving becomes easier. Other features of the invention include smoother skin feel, shorter shaving time, and longer life span of the razor.
