The Expert Copper Rawhide Hammers have two striking faces. These copper and hide faces absorb shock whilst transferring force to minimise the risk of damage. Combined with the iron head, they are ideal for use when a heavy blow is required, with a relatively small striking area. These hammers are commonly used for automotive and engineering applications, such as assembly, repair and maintenance.
