Master Locks have always had little hacks to them - for many years you could find the first position by feeling the tension difference, then the second and third positions were at predefined offsets which would change every few years as the offsets became widely known (pre-internet). My favorites were the keypad locks that allowed the numbers to be entered in any order - after a few weeks of use the paint would wear off the numbers being used so you didn’t need to guess at all - just be patient. Fast forward to today and you have two dozen guys on YouTube tearing down the locks, and you realize that most are only good enough to keep honest people honest.
