[Features] The tip is machined parallel to prevent cam-out and allows for the transmission of high torque without damaging the thread groove. The grips are made from materials including natural ingredients such as wood and cotton. The blade is made of 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. 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.
