The head tube of the SUPERCRAFT hammers is filled with steel scrapes. This causes the scrap filling to follow in a delayed manner when the impact surface hits the workpiece. The impact energy is optimally utilized through the reduced rebound This results in very powerful beats. Moreover, working with SUPERCRAFT hammers is much safer, gentler and quieter than with conventional steel hammers.The impact inserts offer excellent impact properties and enable maximum strength with a highest durability. They are made of extruded, extremely homogeneous material. In comparison to the sprayed plastic inserts, they are thus much more resistant to wear and tear and do not splinter even at minus temperatures.The ergonomically shaped, painted and very stable Hickory handle provides vibration-damping.The handle protection sleeve prevents accidental knocks. A secure stem-head connection is made possible by an aluminum wedge and locking pin. The resistant powder paint coating protects against corrosion.
