A soft-faced hammer or mallet is a hammer designed to offer driving force without damaging surfaces. They also reduce the force transmitted back to the arm or hand of the user, by temporarily deforming more than a metal hammer would.
Mallets. A mallet is a block on a handle, which is usually used for driving chisels. The head on a rubber mallet is made of rubber. These types of hammers deliver softer impact than hammers with metal heads.
Like a hammer, the mallet is also used for hitting objects. One of their main differences is that mallets have only one head and are commonly made of wood or rubber. Since a mallet is made of softer material unlike the metallic hammer, it is used to hit something more gently and not crush or dent the surface.
