Rubber mallets are used when a softer blow is called for than that delivered by a metal hammer. They are typically used to form sheet metal, since they don't leave marks and are softer, as well as for forcing tight-fitting parts together, for shifting plasterboard into place, in upholstery, and a variety of other general purposes, including some toys. It is a tool of preference for wood workers using chisels, with plastic, metal or wooden handles - as they give a softened strike with a positive drive. It is the most commonly used mallet.
