Abstract
Abstract A flexible, sectionalized razor system is provided for shaving rounded or variably contoured shaving surfaces. The system includes a plurality of individual blade-housings, each of which carries a separate blade, wherein the blade-housings are connected by connecting means of either ribs, resilient foam, soft rubber or spring means to a handle. In the preferred embodiment, the blade housings are arranged in such a fashion so as to avoid unshaved ribbons of the shaving surface caused by gaps between adjacent blade-housings. The blade-housings may be mounted peripendicularly to the direction of shaving or angularly to the direction of shaving. Another embodiment provides two parallel rows of blade-housings wherein one row is staggered with respect to the other row.
