An anvil is typically used to

The correct answer is that an anvil is typically used to shape hot metal. Anvils serve as a solid surface on which blacksmiths and metalworkers can hammer heated metal into various shapes and forms. The heavy and flat surface of the anvil absorbs the force from the hammer strikes, allowing the metal to be manipulated effectively without causing damage to the tool itself or the workpiece.

In blacksmithing, when metal is heated to a malleable state, the anvil provides the necessary support to facilitate the shaping process. The metal can be drawn out, bent, or otherwise formed as desired, making the anvil an essential tool in metalworking crafts.

Other options do not relate to the primary function of an anvil. For example, carving wood handles or holding glued wood would require different tools more suited for woodworking. Grinding metal bearings would typically involve grinding machines or whetstones rather than an anvil, which is not designed for such types of work.
