Which tool is an example of a leverage/prying/spreading tool?

A crowbar is classified as a leverage/prying/spreading tool because it is specifically designed to amplify force using a fulcrum, allowing the user to move or separate two objects with greater ease. Its long, curved shape and pointed ends enable it to fit into tight spaces, making it effective for prying open doors, lifting heavy objects, or spreading apart materials. This functionality is essential in rescue operations where quick and efficient access or removal of obstacles is required.

In contrast, the other tools listed serve different purposes. A screwdriver is primarily used for driving screws and does not offer the leverage capabilities of a crowbar. A wrench is designed for gripping and turning nuts and bolts, lacking the prying function entirely. A hammer is mainly a striking tool used for driving nails or breaking objects, which doesn't align with the prying or spreading action characteristic of leverage tools. Hence, the crowbar stands out as the ideal example of a leverage/prying/spreading tool in this context.
