ABSTRACT:
A tandem edge razor blade cartridge has two blades with edge portions bearing cutting edges that are in a spaced-apart, parallel relationship. One of the blades has a major portion, behind the edge portion, bent at a substantial angle to the edge portion, away from the other blade, so that the gap behind the edge portions is greater than that between the edge portions themselves. Other embodiments include one or both blades each having a major portion comprising two components, one at an angle to the edge portion away from the other blade, the second component bent, at the same angle, to the first, back toward the other blade. As a result the second component is parallel to the edge portion, but displaced further than it is from the other blade. Additionally, an embodiment is provided in which the razor blade support has resilient apparatus to allow independent motion of the blades.
