Abstract
Abstract A light weight handle and head carry a blade with a discontinuous cutting edge. The handle extends at an acute angle to the extent of the blade edge. The handle increases in girth from the head to its free end. The head is slotted to receive the blade in a carrier or guard with a "V"-shaped cross-section. The trough of the "V" is perforated to define slim bands that cross the edge of the blade. The perforate edges are contoured to eliminate drag on the skin and hair of the user. The longitudinal axis of the handle is coplanar with the blade and the handle configuration enables the user to rotate the razor head for ease in shaving difficult areas. The carrier interrupts the skin contact of the cutting edge to prevent slicing the skin.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
141 words
In a razor having a removable blade with registry means, the combination comprising a blade head, a top bar on said blade head, a front piece extending from the top bar, a rear piece extending from said top bar spaced from said front piece, walls in the top bar and end front and rear pieces defining blade-receiving slots; a blade carrier adapted to fit the blade-receiving slots, spaced walls on said carrier adapted to embrace the blade, slim bands on the carrier joining said spaced walls and adapted to cross the blade edge to interrupt the cutting edge exposure to the user; a handle extending from the rear piece, the central longitudinal axis of said handle extending in the plane of the blade at an acute angle to the cutting edge, said handle increasing in girth away from the end piece.
Claim 2
Dependent Claim
141 words
In a razor having a removable blade with registry means, the combination comprising a blade head, a top bar on said blade head, a front piece extending from the top bar, a rear piece extending from said top bar spaced from said front piece, walls in the top bar and end front and rear pieces defining blade-receiving slots; a blade carrier adapted to fit the blade-receiving slots, spaced walls on said carrier adapted to embrace the blade, slim bands on the carrier joining said spaced walls and adapted to cross the blade edge to interrupt the cutting edge exposure to the user; a handle extending from the rear piece, the central longitudinal axis of said handle extending in the plane of the blade at an acute angle to the cutting edge, said handle increasing in girth away from the end piece.
Claim 3
Dependent Claim
24 words
