Abstract
A vitreous enamel coating for an electrosurgical metal cutting blade, the coating having a coefficient of thermal expansion substantially near the coefficient of thermal expansion of the metal cutting blade. Selection of materials having similar coefficients of thermal expansion results in an electrosurgical cutting blade with an improved insulating layer, substantially improved durability, or both.
