Hammers are essential hand tools used for driving nails, fitting parts, and breaking apart objects. They consist of a heavy 'head' attached to a long handle, allowing for effective force application. Different types of hammers, such as claw hammers and sledgehammers, serve various purposes in construction and woodworking. The design of a hammer can vary significantly based on its intended use. For instance, a ball-peen hammer is commonly used in metalworking, while a rubber mallet is ideal for tasks that require a softer touch. Understanding the right hammer for a job can greatly enhance efficiency and safety.
