Which tool is specifically designed to pull the lock cylinder out of a door?

The K tool is specifically designed to extract the lock cylinder from most types of door locks. This tool features a unique design that allows firefighters to easily manipulate the locking mechanism without causing significant damage to the door itself. By inserting the K tool into the lock, firefighters can pull out the cylinder, which may enable entry through traditional means or afford access to inside mechanisms that can facilitate door opening.

The other tools mentioned serve different purposes. The Clements hook is primarily used for various hauling tasks and manipulating objects during firefighting operations, while the adze is a cutting tool typically used for shaping or smoothing wood. The spring-loaded center punch is useful in creating starting points for drilling but does not function in removing lock cylinders. Thus, among the choices, the K tool is uniquely advantageous for its intended application of extracting lock cylinders efficiently.
