An apparatus and method for treating a cutting edge with a carbide coating to form a high endurance cutting edge that is self sharpening. The cutting edge has one side of its bevel treated with an electronically impregnated coating to create a wear resistant surface employing Tungsten, Titanium or Vanadium Carbide. The coating providing an abrasion resistant cutting edge and creates a differential hardness on the total cutting edge thereby extending its cutting ability through a wear-resistant surface on its treated face and a faster wear on the untreated surface causing the cutting edge to be self sharpening.
