Hammer is a tool that can be used to drive nails and other fasteners into wood, metal, and other materials. It’s made up of two parts: the head and the handle. The head is usually made of steel or iron, and it has a flat face and a rounded end. The handle is usually made of wood, plastic, or metal, and it is designed to fit comfortably in your hand.
