Razors and razor blade cartridges and methods of manufacture therefore

A razor cartridge 1 includes at least one razor blade 3 and a housing 5 made from a polymer material. The housing has an outer surface that is at least partially coated with a hydrophilic material. In one embodiment at least a portion of the coated part of the housing comprises undulations (12, fig. 3) preferably comprising ridges (13) and troughs (14). The outer surface is preferably a vinyl monomer such as an acrylamide. The hydrophilic coating may be applied at a thickness that extends higher than the height of the undulations such that the troughs are completely filled with coating material. The undulations or texturing may be formed by etching or other methods of micromachining and result in greater adhesion of the coating to the outer surface and improved friction properties.
