What component does a Halligan tool feature alongside a sharp pick and a flat prying surface?

The Halligan tool is specifically designed as a forcible entry tool and it features a distinct combination of prying and striking components. Among these components is a flat prying surface, a sharp pick, and, importantly, a forked claw. This claw is particularly effective for various tasks, such as opening doors, breaking windows, and manipulating other structures during rescue or firefighting operations. Its design allows firefighters to engage with and pull apart materials effectively, making it an essential tool on the fireground.

The other options do not align with the well-established design of the Halligan tool. For example, a serrated blade or a spring-loaded center punch does not typically belong to this tool's configuration, as the Halligan’s purpose is not to cut or punch but rather to pry and lever. Similarly, while a piked hook implies a hook-like tool, the Halligan specifically utilizes the forked claw design which is better suited for the types of forcible entry situations firefighters encounter.
