An anvil is typically used to?

An anvil is primarily used in metalworking, where its main function is to shape hot metal. When blacksmiths heat metal until it becomes malleable, they place it on the anvil, which provides a strong, solid surface for the metal to be worked. Using hammers or other tools, craftsmen can shape the heated metal into various forms, such as tools, horseshoes, or decorative items. The heavy and flat surface of the anvil allows for effective shaping and forging due to the resistance it provides against the blows of the hammer, making it an essential tool in the metalworking process. The other options, while they may relate to tools or working with materials, do not accurately describe the primary function of an anvil.
