Abstract
Shaving systems are designed to provide greater uniformity to shaving forces over the skin-engaging portion of the skin-engaging element, such as a blade, guard element or cap member. According to one embodiment, at least one, and preferably a plurality of flexible blades are movably connected to a support by biasing members. One embodiment comprises a razor head comprising a plurality of blades which are movably connected to a flexible support structure in a manner which permits movement of the blades independent of the flexing of the blade(s) or the flexible support. According to another embodiment, at least one and most preferably a plurality of blades are connected to a support block which is movably supported in a “floating” manner within a housing by biasing members.
