Tooling parts such as cutting knives, bearings, gears and the like are constructed from advanced wear ceramics and fiber reinforced polymer material. The cutting knives are constructed from a plurality of ceramic blades molecular bonded or embedded in a support of reinforced polymer material. The resulting cutting blades are light in weight, inert to chemical attack, and maintain their sharpness during the processing of various materials such as plastics, wood, paper, cardboard and the like.
