Intro: Hi, my name is Michael Huebler, I’m a lock collector from Germany, and in March 2008 I was very lucky to receive a sample of a very interesting new padlock that was not yet available on the market – a combination lock from Master Lock® with a unique new user interface and a very clever mechanism inside. Inspired by other papers on lock designs, such as the Abloy series by Han Fey, I decided to share the details of this nice piece of mechanical engineering with you, and I hope you enjoy reading about them as much as I enjoyed disassembling and analyzing the actual lock. As of July 2009, the lock has reached the market; it is named “Speed Dial™” in North America and “ONE™” in Europe. Both versions come in four different color combinations, and the North American version has a different knob design. I would be very happy to receive your comments, corrections, or just a short note whether you found this paper interesting or helpful. You can contact me at ->mh (at) The Open Source Lock (dot) org<- You can find the most recent version of this paper as well as a free software program that visualizes the mechanism of this lock for you at http://www.toool.nl/. Thanks for your interest!
- This is the HAR2009 edition, with some major corrections regarding the angles that can be reached by the combination disks; thanks to Yehonatan Knoll for advising me about this mistake in the earlier versions of the paper.
