Abstract
In a shaving instrument including a razor blade having an edge attached to one end of a support and a guard bar arranged in precise spaced relation parallel to said razor blade edge, the improvement of a patterned texture on a region of an outer surface of the guard bar, the texture including one or more depressions each having a mound of minute height which constitutes a border of each depression, the material of each mound formed by a solidified part of the material which was melted and displaced from the guard bar to form the depressions; the texture being positioned such that when the shaving instrument is slidingly applied to skin having hair extending therefrom, the texture exerts a degree of drag or friction thereto which causes the skin to be pulled slightly and the hair to be properly positioned for cutting by the blade edge. The texture is imprinted upon the guard bar by a high energy beam, preferably from a YAG-Nd laser.
