BALL PEIN HAMMER

A Ball Pein Hammer is a hammer with two ends on the head; one that is round and the other flat. Sometimes called a machinist's hammer; a ball pein is a good choice for working with metal. Its steel head is harder than that of a claw hammer; so is less likely to chip on impact. Ball pein hammers are commonly used to drive cold chisels; set rivets; and bend and shape metal.
