Abstract
According to this invention a disposable, moldable plastic razor is made by a single multi stage molding process. This is accomplished by molding a blade support around a single narrow blade and using the combination of blade support and blade as the basis for subsequently molding the other moldable plastic razor elements. In another aspect of this invention, a subassembly comprising blade support and blade is provided having certain defined spatial characteristics which provides the first "building block" for the assembled disposable razor.
