CUTAWAY LOCKS
For most the hardest part of learning to pick locks open is visualising what your tools are doing inside the lock. Clearly, a window in the side of a lock is a huge advantage to picking a lock open. Seeing your picks interact with the pins. Knowing what pins are set and what pins still need to be worked on. It makes opening a lock so much easier and significantly reduces the amount of time it takes to learn lockpicking. Cutaway locks help you learn what it feels like when you lift a pin, set a pin or over-set a pin because you can see your tools interact with the lock.
