  • Patent number: 4791724
    Abstract: An improved razor apparatus is provided to enable use in two positions for shaving. The improved razor apparatus includes two components, an easily adjustable razor body and a handle. The razor body is comprised of dual razor heads which may be easily adjusted from a wedge-shaped position to a straight edge position, by applying pressure, such as made by a finger, to a hinged razor cap crown connecting the dual razor-heads. The razor body maintains its wedge-shaped position by means of a locking clasp placed between the sides of the hinged razor cap crown. The handle is demountably attached to the dual razor heads by flexible arms, allowing adjustment between the wedge-shaped position and straight edge position without detachment of the pair of arms.
