This high quality Challenge replacement cutting blade is designed to provide superior cutting performance and extended cutting life. It is always a good ideal to have an extra blade or knife on hand when you send your other blade out for sharpening or in case you need to replace a blade that has been repeatedly sharpened or has become nicked.
This knife has a bi-metallic composition consisting of one part Tungsten High Speed Steel and one part standard grade steel. A special fusion process bonds these two grades of steel together to produce an extremely wear resistant knife. Expect three to five times the life of conventional blades
