Good analogy! And that makes logical sense … My first thought was "I wonder if lockmakers are really protective of their methods / manufacturing process," but realized this information would matter little: the point is that it doesn't matter if people know exactly how the lock is made, because it doesn't make it any faster to open it, and I've only got 2 hands and 24 hours in a day and the time just isn't worth the risk.
