The blade portion made of a rubber silicone compound which resists melting, burning, cracking, discoloring, or permanently bending, even under vigorous cooking situations. The handle is made of a heat-resistant glass reinforced PBT resin which is not susceptible to melting, scorching, absorbing odors, or discoloring. In addition, the molding process between the handle and the blade resists separation of the two parts and eliminates gaps which could house bacteria.
