Abstract An improvement in hair guiding and skin stretching means mounted on a shaver having a cutter which contacts the user''s skin as the shaver is moved in a hair shearing path across the user''s skin. The improvement includes a first member, for combing hair and stretching skin, in combination with a second member, for lifting hair and stretching skin. The first and second members are connected alongside of the cutter to contact the skin ahead of the cutter as the shaver is advanced in the hair shearing path of movement across the user''s skin, the first member stretching the skin and combing the long hair in advance of the second member, and the second member further stretching the skin and lifting the short hairs from the surface of the skin in advance of the cutter.
