This tool is the most popular and most common form of lock picking. The bent tool describes a curve between 90 and 180 degrees.
These picks are exclusively used for setting cylinder pins. Starting from the back, one pin after the other is individually felt and pressed down. At the same time, the cylinder is tensioned using the tension tool. Thus, the pins cannot reset after being set.
The hook pick functions the same for every angle. However, acute-angled hook picks are more suitable for pressing the pins in small or more complicated locks, as they allow more accurate working. Obtuse angles are often more suitable for fast, but inaccurate pin setting.
