A hammer is a simple tool used to drive nails into wood or other materials. It typically consists of a heavy head attached to a long handle, allowing for powerful swings. Hammers come in various types, such as the claw hammer, which has a forked end for removing nails, and the sledgehammer, which is heavier and used for breaking hard surfaces. Hammers are essential in construction and woodworking, making them a staple in many toolboxes. They can also be used in crafts and DIY projects, helping people create or repair items around the home. With the right technique, anyone can use a hammer effectively!
