Plug spinner is a specialised tool used by locksmiths to rotate the plug of a lock cylinder rapidly in the opposite direction once the pins are set, allowing the lock to open without a key. Designed to correct the orientation of the plug when picking has set the pins, but the lock has not opened due to incorrect plug rotation, this tool offers a swift solution for such scenarios. It consists of a handle and a trigger mechanism that, when activated, causes a quick, forceful spin of the lock plug. This action can prevent the need to repick the lock from scratch, saving time and effort.
The utility of the plug spinner lies in its precision and speed, providing a mechanical advantage by generating a rapid rotational force that manual manipulation cannot achieve. Suitable for a variety of lock types including pin tumbler and wafer locks, the plug spinner is an indispensable asset in a professional locksmith's toolkit. It is particularly useful in situations where the lock is picked in the wrong rotational direction, necessitating a quick correction that does not damage the lock mechanism. Its design and functionality underscore its role in advanced lock manipulation techniques, pushing the boundaries of traditional lock picking methods.
