Which of the following striking tools has an axe on one end and a sledgehammer on the other side?

The maul is designed specifically with a dual-purpose head, featuring an axe on one end and a sledgehammer on the other. This design allows for versatile use; the axe side is effective for chopping through wood or other materials, while the sledgehammer side is ideal for driving stakes or breaking down barriers. The combination of an axe and a sledgehammer in a single tool enhances the efficiency of a firefighter when performing tasks that require both cutting and striking actions, making it especially valuable during emergency situations.

In contrast, a pickhead axe primarily serves as a cutting tool and does not have the sledgehammer side. The flathead axe offers a similar chopping function but is also not equipped with a sledgehammer feature. The ball peen hammer is a specialized tool used mostly in metalwork and is not designed for striking or cutting wood. Therefore, the maul stands out as the correct choice due to its unique and practical design for the intended fire service applications.
