Abstract: A blade cartridge for a wet shave razor includes multiple blades that are electrically connected in series to a power source, such as a battery power source, wherein the blades are heated as a result of electrical resistance created by the electric current flow through the blades. The electric current flow through the blades creates a magnetic field around each of the blades, which is opposite in polarity to adjacent blades due to the blades being electrically connected in series, wherein current flow is in opposite direction in each adjacently positioned blade. A method of vibrating the blades includes the step of rapidly alternating direction of current flow to change the polarity of electric fields around each blade to cause momentary attraction between adjacent blades in rapid impulses (e.g., 700 hz to 75 khz) that results in vibration of the blades.
