Which tool is specifically used to drive nails or perform heavy impact tasks?

The sledgehammer is specifically designed for driving nails or performing heavy impact tasks due to its large size and weight. Its substantial mass allows it to deliver a significant force with each swing, making it ideal for driving stakes, breaking apart materials, or other tasks that require a greater impact than what lighter hammers can provide. The broad striking surface also helps to distribute the force over a larger area, reducing the likelihood of damage to the surrounding materials.

In contrast, a prybar is primarily used for leverage, such as removing nails or lifting heavy objects, rather than delivering heavy impacts. An air hammer is more suited for chiseling, cutting, and shaping materials through rapid vibrations rather than driving nails. A ball peen hammer is typically used in metalworking for tasks like shaping and peening metal, but it is not designed for heavy impact like a sledgehammer.
