I've always been fascinated by locks, for some odd reason. Master combination locks, the combination lock of choice for most of us it seems, are everywhere and were a staple for my existence as a student. Hall lockers needed a combination lock, gym lockers, orchestra lockers, etc... The result? Well, years past high school, I now have 3 or 4 master locks that I don't have the combinations for. Thankfully, I found this site and the software tool that was created from it to find combinations! I even assembled a PDF document listing the instructions and all possible combinations once the last number was found. Great to print out and keep on hand, especially if you don't remember where you downloaded the software! You can download the PDF here.
