Lock picks are specialized tools used to manipulate the components of a lock, allowing it to be opened without a key. They come in various shapes and sizes, designed to fit different types of locks. The most common types of lock picks include tension wrenches and hook picks, which work together to align the pins inside a lock cylinder. Using lock picks requires skill and practice, as the user must feel for the pins and apply the right amount of tension. While often associated with locksmithing, lock picking can also be a hobby for enthusiasts who enjoy the challenge of opening locks without keys.
