A mallet is a tool used for imparting force on another object, often made of rubber or sometimes wood, that is smaller than a maul or beetle, and usually has a relatively large head. The term is descriptive of the overall size and proportions of the tool, and not the materials it may be made of, though most mallets have striking faces that are softer than steel. Mallets are used in various industries, such as upholstery work, and a variety of other general purposes. 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. Wooden mallets are usually used in carpentry to knock wooden pieces together, or to drive dowels, chisels and to apply pressure on joints. A wooden mallet will not deform the striking end of a metal tool, as most metal hammers would. It is also used to reduce the force driving the cutting edge of a chisel, giving better control. Hardwood mallets are also used to knock in cricket bats. Copper, brass and leaden mallets are typically used on machinery to apply force to parts with a reduced risk of damaging them, and to avoid sparks. As these metals are softer than steel, the mallet is deformed by any excessive force, rather than any steel object it is hitting. Meat mallets tenderise or flatten meat. Made from wood or metal, they are typically two-sided, one flat or with slight bumps, and the other with more pronounced protrusions. Their use has been reduced with the invention of cube steak machines and other electric tenderisers, but they can still be readily found at cookery stores and in professional use. Less common mallets include: Rawhide mallets, which may employ rawhide covering a steel head, or simply consist of rolled-up rawhide, are used for leatherwork, jewellery, and assembling electric motors and delicate machinery. Plastic mallets, made of nylon, polycarbonate, or polystyrene are used especially in leatherwork and jewellery. Split head mallets have removable faces which can be changed to an appropriate material for the job.
