ABSTRACT:
A razor blade unit includes a plastic support member having a guide surface and a top cap. At least one razor blade having a cutting edge is embedded in the support member. At least one freely rotatable cylindrical roller is attached axially to the support member and extends parallel to the cutting edge of the razor blade to engage a skin area. A cylindrical roller has a lower coefficient of friction than the plastic support member. The cylindrical roller was preferably made of metal and is located in the guide surface and/or in the top cap of the razor blade unit.
