This series of lock is progressively pinned with 2,3,4 and 5 pins to accommodate your learning curve from beginner to advanced levels. The locks have a cutaway window so you can easily associate what you're feeling through the lock pick and tensioner with what you're seeing happening in the lock. These locks will definitely accelerate you skills. Like this video?
