A traditional hammer can potentially damage softer, more delicate materials. When working with these types of materials, a mallet or dead-blow hammer is a smart choice. At Tools Plus we carry a wide variety of mallets and dead blow hammers that will protect the fragile material you work with. Rawhide mallets, like the Vaughan CR150, are used for leatherwork, jewelry, and assembling electric motors. Copper mallets reduce the chance of sparks when working on machinery. This is due to the fact that copper is a much softer metal, so the mallet is deformed rather than any steel object it is hitting. The rubber mallet is typically used to form sheet metal, since it does not leave a mark and the blow is softer than that delivered by a metal hammer.
