The lubricant-applying safety razor includes single or multiple cutting blades supported in a blade-supporting head and a lubricant roll is supported by the blade-supporting head in a position in advance of the cutting edges of the blades when the safety razor is moved along the skin of the user in a shaving motion. The lubricant roll has a peripheral surface for engaging the skin of the user in advance of the cutting edges of the blades and is provided to apply a thin lubricous film to the skin in advance of the cutting edges for the purpose of reducing the coefficient of friction between the wet skin surface and the lubricous film. The peripheral surface of the lubricant roll initially positions the skin surface in a limited angular relationship with the blades. With continued use of the razor, the lubricant roll begins to wear away and thereby lowers so that the angular relationship between the cutting blades and the skin surface gradually increases. After the lubricant roll has been worn away in one fixed position, it may be indexed or rotated to another position to present a new peripheral surface to be engaged by the skin of the user.
