In a recent thread, there was some discussion about the notion of lockpicking as a hobby. It seemed that there are people who don't believe that anyone but a working locksmith, or a wanna be thief, would be interested in learning to pick locks.
With all due respect to the trade and its traditions (which I know go back a long time) here is some information about this hobby.
For better or worse, it does exist. I would like to thank the people on this group, especially Stormin' Mormon, for helping me see that the physical nature of locks as a security tool does make it different from the software security tools I am more familiar with.
