Claim:
1. A razor blade heating system comprising: at least one electrically conductive blade formed as a unitary body and being structured and disposed for receiving an electric current flow through said unitary body, and having a top side, a bottom side, a front cutting edge, at least one back non-cutting edge and a back surface between the at least one back non-cutting edge and the top side, and the top side extending from the front cutting edge to the at least one back non-cutting edge, the bottom side extending from the front cutting edge to the back surface, and the at least one electrically conductive blade further including opposite outboard ends; a blade cartridge structured and configured for containing said at least one electrically conductive blade within said cartridge so that the cutting edge is operatively positioned for cutting hairs when the blade cartridge is moved along the skin surface of a user; at least one electrically conductive contact segment held in contact with the at least one back non-cutting edge and the back surface of said at least one electrically conductive blade for delivering an electric current from a power source to the at least one back non-cutting edge and into the unitary body defining the at least one electrically conductive blade so that the electric current flows through said at least one electrically conductive blade and said at least one electrically conductive blade is heated across an entire length of the blade; at least one wire conductor connecting between the power source and said at least one electrically conductive contact segment for directing flow of the electric current from the power source to said at least one electrically conductive contact segment; and said at least one electrically conductive contact segment having a higher electrically conductive resistance than said at least one wire conductor, thereby causing the at least one electrically conductive contact segment to increase in temperature and release heat towards the skin surface of the user when the electric current flows through said at least one electrically conductive contact segment and the blade cartridge is moved along the skin surface of the user.
