They are also known as serrated helicon sheeter Knives. The sheeting process generally consists of helico-sheeter knives and serrated helico-sheeter knives working together. Even at high speed operation, high shear strength and dimensionally accurate bevels enable excellent cut and the cutting edge without stress. Not only the balance of toughness and hardness, but dedicated performance over a long time and close tolerances suitable for all kinds of machine types. Clean and sharp bevel reduces the machine load and enhances long lasting life.
