A functional polymeric cutting edge structure and methods for the manufacturing cutting edge structures using polymeric materials are provided. A razor blade for use in a razor cartridge or a blade box for assembly in a razor cartridge frame may be formed using the present invention.

This invention relates to a novel of making a personal care product including the steps of providing a treatment sheet comprised of a first material and a first plurality of apertures and joining a support structure to the lower surface of the treatment sheet. The support structure includes a support material, a support sheet, a support ring, or any combination thereof. The support sheet includes a second plurality of apertures. The support sheet is disposed beneath the treatment sheet by aligning the first plurality of apertures and the second plurality of apertures. Fluid support material is solidified such that the treatment sheet and the support sheet are bonded together. The support ring is disposed on a housing (e.g., in a groove) below the support sheet or joined to the treatment sheet via the support material prior to solidifying.
