Rubber mallets and dead blow hammers work well for striking nonsharp surfaces without damaging to the work surface. Dead blow hammers contain sand or shot that helps give them striking force with reduced rebound. They are used for setting pavers or concrete blocks that could crack if struck with a regular hammer. Beechwood, rawhide and rubber mallets provide a softer face that can strike without marking surfaces. These mallets help build furniture, shape metal or position automotive parts or woodworking materials.
