HammersA hammer is a hand tool used for striking or pounding objects. It consists of a handle attached to a heavy head made of metal, wood, or other materials. Hammers are used in a wide range of applications, including construction, carpentry, metalworking, and automotive repair. The most common type of hammer is the claw hammer, which is used for general-purpose tasks such as driving nails and removing them. Other types of hammers include ball peen hammers, which are used for shaping metal; dead blow hammers, which have a heavy head filled with sand or shot to minimize rebound; and sledgehammers, which are used for heavy-duty tasks such as demolition.
