This high quality Diamond Cut Challenge CMT 330 3-Knife High Speed Steel Replacement Blade is designed to provide superior cutting performance and extended cutting life. Our razor sharp replacement paper cutter blades are manufactured to precise OEM specifications and will outperform similar blades from other manufacturers. An extra blade or knife is a great investment, especially when you need to send another blade to be sharpened or replaced all together because it has been repeatedly sharpened or nicked. This particular knife has a bi-metallic composition consisting of one part 18% T1 German 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. Product number JH-31470HSS.
