The grip is made from CAB (Cellulose Aceto Butyrate), a natural material derived from wood and cotton. The grip is gentle on the skin, ideal for gripping, impact resistant and easy to clean. A favorite for decades, the grooved grip provides a comfortable grip and ensures high torque transmission. The blade is made from PB's proprietary special alloy, which combines excellent hardness and toughness. A five-digit production number is inscribed on the blade, which can be used to trace the manufacturing process back to the raw material stage.
