Patent attributes
In a razor cartridge, a frame has an opening defined in part by a leading surface and a trailing surface. Positioned within the opening are a plurality of cutting edges, each cutting edge defined by a blade. In a shaving operation, a hirsute surface contacts in turn the leading surface, cutting edges, and the trailing surface. A contact plane is defined between the leading surface and the trailing surface that provides a reference for determining whether a cutting edge has a neutral, positive, or negative exposure. All of the cutting edges within the razor cartridge have an exposure relative to the contact plane that is one of all positive or all negative.
