<p>In a razor cartridge (14), a frame (16) has an opening (18) defined in part by a leading surface (30) and a trailing surface (32) Positioned within the opening (18) are a plurality of cutting edges (22), each cutting edge (22) defined by a blade (20). In a shaving operation, a hirsute surface contacts in turn the leading surface (30), cutting edges (22), and the trailing surface (32). A contact plane (38) is defined between the leading surface (30) and the trailing surface (32) that provides a reference for determining whether a cutting edge (22) has a neutral, positive, or negative exposure. All of the cutting edges (22) within the razor cartridge (14) have an exposure relative to the contact plane (38) that is one of all positive or all negative.</p> |
