ABSTRACT:
This invention provides a device to shave concave areas utilizing a blade bent into an arc where the blade sharpened edge is mounted on a cylindrical or conical surface in a convex shape. In one embodiment the lead in surface is a spherical segment with grooves to guide hairs and the blade edge is mounted projecting slightly over a slot located at the intersection between the cylindrical and the spherical surfaces. This method allows nick free shaving of concavities.
