Which tool combines features of an axe and a sledgehammer?

The correct answer is a maul, which combines the cutting features of an axe with the heavy striking capability of a sledgehammer. A maul typically has a broad, heavy blade on one side designed for chopping and splitting wood, while the opposite side resembles a sledge hammer, allowing it to deliver significant force for driving wedges or breaking through barriers. This dual function makes the maul a versatile tool in firefighting and rescue operations, especially when dealing with wood and other materials.

The other options do not serve this dual purpose. A flat head axe is primarily designed for cutting and does not include the striking weight of a sledgehammer. A pick-head axe features a pointed pick on one side and an axe blade on the other but lacks the heavy striking ability of a maul. A rabbit tool is specialized for prying and cutting but does not combine the characteristics of an axe and a sledgehammer. Therefore, the maul stands out as the tool that effectively merges these two functionalities.
