Abstract
A functional polymeric cutting edge structure and methods for the manufacturing of cutting edge structures comprised of polymeric materials are provided. The cutting edge structures may be produced on a substrate having a blade body or blade support type. The polymeric material is produced by curing a precursor material by electromagnetic radiation wherein a wavelength of said radiation is about double a wavelength required to cure the precursor material. A razor blade for use in a razor cartridge or a blade box may be formed using the present invention.
