Which tool is commonly used to drive nails?

The claw hammer is the correct choice for driving nails because it is specifically designed for this purpose. Its head includes a flat striking surface that allows for effective and controlled impact on the nail, driving it into the material. Additionally, the claw end of the hammer can be used to remove nails, making it a versatile tool for various tasks in woodworking and construction.

In contrast, a crosscut saw is primarily used for cutting wood across the grain rather than driving nails, while a keyhole saw is designed for making intricate cuts in thin materials. A Phillips head screwdriver is intended for inserting or removing screws, not for driving nails, showcasing that each tool serves a distinct function tailored to its specific design and purpose.
