Abstract
A razor cartridge is provided that includes a frame, at least four razor blades, a guard that includes a contact surface, and a cap that includes a contact surface. The razor blades are supported by the frame. The guard is disposed forward of the razor blades and the cap is disposed aft of the razor blades. The razor blades are arranged so that the cutting edge of each razor blade is adjacent a plane that tangentially intersects the contact surfaces of the guard and the cap. As a result, each stroke of the razor exposes the surface being shaved to at least four razor blade cutting edges in succession. A unitary razor assembly that includes a head characterized in the same manner as the above-described cartridge is also provided.
