Abstract

Abstract This invention is concerned with the mounting of a flexible razor blade on a flexible holder such that the blade may be flexed about an arc having a radius as small as 1/8'' or smaller to permit the blade to flow over protrusions or be flexed to shave through dimpled areas of the skin being shaved. The razor is useful for shaving over the jaw bone or shin bone areas for example without cutting the skin and may be pressed by the fingers of the user to delicately shave most any contoured area found on the normal skin of a human being.
