Probably the most common combination padlock used today is the Master Lock combination padlock. Master Lock combination padlocks are typically found securing lockers, bicycles, and gates and are used in many other security applications. Harry E. Soref, a locksmith and inventor, and James Keith Marshall were awarded a patent for the Master Lock combination padlock on April 30, 1935. The Master Lock combination padlock has a pressed steel case, which is press fitted and spun over the back cover, making it impractical to disassemble the lock.
