A blade cartridge for a shaving razor contains a series of parallel blades, and at least two wire conductors of an electric circuit connected to the blades at spaced intervals to provide an electric current flow through the blades in a manner that provides more efficient heat distribution across the length of the blades. The ends of the blades may be held in place by staples that are insulated from the electric circuit. A thin conductive film may be fitted to be in contact with the ends of the blades to insure conductivity throughout the entire length of each blade.
