The head tube of the Supercraft soft hammers is filled with steel shot. This causes the shot filling to follow with a delay upon impact of the striking surface on the workpiece. The reduced rebound allows for optimal utilization of the striking energy, enabling very powerful blows. Furthermore, working with Supercraft soft hammers is significantly safer, more joint-friendly, and quieter than with ordinary steel hammers. The striking inserts offer outstanding striking properties and allow for maximum strength with the highest durability. They are made from extruded, extremely homogeneous material. Compared to injected plastic inserts, they are much more wear-resistant and robust, and they do not splinter even at low temperatures. The ergonomically shaped, painted, and very stable hickory handle acts as a vibration dampener. The handle protection sleeve prevents misstrikes. A secure handle-head connection is ensured by an aluminum wedge and securing pin. All weld seams are completely robot-welded. An extremely dense and high-quality weld between the impact plate and hammer head prevents the escape of the shot filling even under maximum load. The durable powder coating protects against corrosion. The handle and striking inserts are interchangeable.
