Paper Cutters — Honing a Competitive Edge

Heat treating and carbide applications have become common practices for increasing knife durability. But now, Cryocore, in Wallingford, PA, is among the pioneering companies hoping the industry will warm up to the concept of cryogenic treatment. The process of slowly lowering the temperature of metal to -320°F in a computer-controlled cryogenic chamber realigns the material's molecules into a more orderly orientation, explains Bill Foth, operations manager. "This greatly extends the usable life of any metal item that rolls, impacts, cuts or slices," he adds.
