Which tool is used along with a pin punch to remove a rivet shank?

The ball peen hammer is the correct tool to use in conjunction with a pin punch for removing a rivet shank because it is specifically designed for shaping and driving metal. Its rounded peen is effective for transferring force to the punch, which is needed to drive the rivet shank out of the material. When striking the pin punch with a ball peen hammer, the impact is enough to dislodge the rivet while minimizing damage to the surrounding material.

Using a claw hammer would not be suitable for this task, as its design is more focused on pulling nails rather than providing the assertive force needed to drive punches into metal. A flathead screwdriver lacks the mass and impact force required for this type of metalworking application. Similarly, a torque wrench is not relevant in this context, as it is primarily used for applying a specific torque to nuts and bolts, rather than driving tools for removing rivets.
