  • Patent number: 5343622
    Abstract: A bi-directional razor device is formed of a narrow, elongated head and a transversely extending, integral hand grip formed of molded plastic material. Two pair of narrow, strip-like razor blades are embedded in the head, with one pair extending in one direction and the other pair extending in an opposite direction at an acute angle relative to the first pair. The blades extend along the length of the head. Thus, the user may move the razor head in one direction for contacting one pair of blades against the user's skin for cutting hair and then move the handle in the opposite direction while the blades remain engaged upon the skin for cutting hair in both directions.
