The hook pick is the tool most commonly used for manipulating pins in a lock due to its design which allows for precise control and access to individual pins. The hook shape is specifically crafted to lift or set the pins to the correct height necessary for the lock to turn. By applying targeted pressure, a locksmith can feel for the binding pins and effectively manipulate them one at a time, making the hook pick especially advantageous in pin-tumbler locks.

In contrast, the straight pick typically serves a different role, focusing on sliding between pins rather than manipulating them individually. The pistol grip and rake picks are geared toward specific techniques such as raking multiple pins at once for quicker entry, but they do not provide the same level of finesse required for pin manipulation as the hook pick does. Understanding the specific functionalities of these picks is crucial for effective locksmithing, particularly in scenarios where precision and control are needed to successfully navigate and open locks.
