The impact resistant striking faces shape themselves to the component being struck, minimising rebound damage to the component and reducing noise pollution in the work place. The striking faces can be easily replaced once they have become worn. Available as standard, with a choice of five interchangeable face types. Dual Purpose Rawhide and Copper Faced Hammers Malleable iron head with solid wooden handle.
