A razor blade has a first and a second portion. The first portion has a cutting edge at an exterior end and is angled relative to the second portion by a bending process. A bent region that can be arcuate is intermediate the first and second portions. The razor blade is manufactured from martensitic stainless steel being mostly iron and having (by weight): 0.40 to 0.60% C; 0.30 to 0.55% Si; 0.70 to 0.90% Mn; 13.0 to 14.0% Cr; 0.50 to 1.0% Mo; and 0.03 to 0.2%, more preferably 0.03-0.1% N.

A functional polymeric cutting edge structure and methods for 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.

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.

A razor blade including a substrate with a cutting edge portion ending in a sharpened tip. The substrate having a thickness of between 1.55 and 1.97 micrometers measured at a distance of five micrometers from the tip, a thickness of between 4.6 and 6.34 micrometers measured at a distance of twenty micrometers from the tip, and a thickness of between 19.8 and 27.12 micrometers measured at a distance of one hundred micrometers from the tip.

An intelligent shaving system is disclosed herein including a system having a handle, at least one blade connected to the handle, a microcontroller attached to the handle, a wireless communication unit configured to send and receive data from microcontroller to an external device, a memory configured to store data applicable to the at least one blade, and one or more sensors configured to send sensory data from the one or more sensors to microcontroller. The one of the one or more sensors is a proximity sensor or a camera having image sensor configured to capture video and/or still images. The shaving system assists in determining blade attrition and provides indicators to assist in shaving techniques. The shaving system further may include at least one blade slightly curved to follow a tangent of the skin. The at least one blade may have a nanolattice structure.
