Abstract
Abstract Shaving systems having a plurality of cutting edges. At least one fencing element is disposed proximate one cutting edge to prevent a plurality of discrete portions of that first cutting edge from contacting the skin surface being shaved. The other cutting edge is provided with a substantially continuously unobstructed cutting edge. The present invention provides a razor head design permitting skin flow characteristics of shaving to be altered by the fenced blade to affect safety in shaving while the substantially continuously unobstructed cutting edge is exposed to deliver a closeness not obtainable with a totally fenced shaving system.
