Century Dictionary and Cyclopedia

1. n. A sharp-edged instrument used for shaving the face or head. The blade is usually made with a thick rounded back, sides hollowed or sloping to a very thin edge, and a tang by which it is pivoted to and swings freely in a twoleafed handle. The tang has a prolongation by the aid of which the razor is firmly grasped and controlled. There are also razors formed on the principle of the carpenters' plane, by the use of which the risk of cutting the skin is avoided. In Eastern countries razors are made with an immovable handle continuous with the blade. Compare rattler, 5.
