Which tool is classified as a rotating tool?

A screwdriver is classified as a rotating tool because it is specifically designed to drive screws or remove them by twisting the tool's handle, thus causing the blade to rotate. This rotational motion is essential in how the tool functions, allowing for the insertion or extraction of screws in various materials.

In contrast, the Halligan, pike pole, and pry bar serve different purposes and do not exhibit the rotational motion characteristic of a screwdriver. The Halligan is a multi-purpose forcible entry tool that combines features for prying, striking, and hooking; the pike pole is primarily used for pulling down ceilings or securing materials; and the pry bar is utilized for prying and levering objects apart without the use of rotation. Each of these tools has its own specific application related to firefighting but does not operate through a rotational mechanism like the screwdriver does.
