Hammers are used to drive nails into wood. Hammers come in a variety of sizes, shapes, and weights depending on the job they are designed for. For example, a framing hammer is designed to be used with nails that are about 1/4 inch thick. A claw hammer is designed to be used with nails that are about 3/8 inch thick.
