Abstract
A razor for shaving hair from the skin of a user includes a rotating blade assembly connected so as to be rotated by a drive mechanism. The blade assembly includes a generally cylindrical roller rotatably mounted along its longitudinal axis, at least one blade mounted on, and extending along a major part of, the roller, and a guide element associated with each blade. The blade and the guide element are configured to form a safety blade such that, when the blade assembly rotates in direct contact with the skin, the at least one blade shaves hair from the skin without cutting the skin. Preferably, the razor includes two similar blade assemblies rotated by the drive mechanism in opposing directions so as to apply stretching tension to the skin of the user. Also described are a number of safety blade configurations relevant to both manual and power driven exposed-blade razors.
