The world famous BMW/PEUGEOT HU92 Inner Groove Lock Pick.??
The wrench holds the flap open and applies a gentle tension. The pick is inserted and the lock 'raked' by??repeatedly??pushing it in and out. The tool has half-diamond-like picks that are curved into the right tension to set the wafers in the lock.??
Some locks will open quickly and with ease whereas others might take a little longer. Like any Lock Picks you'll learn through time how to 'read' the lock and to know what speed to use and what tension to apply. Some people take a tool to the rakes and bend them out or in depending on how they want to adjust them for the particular lock they're working on. Most people however trust the tool and it's no surprise these tools have become standard it in many an auto-locksmiths bag.
