Well, I've personally only made standard types of tools, like different Bogotas, tweaked L/City rakes, bump keys, reach tools, wrenches and so forth, so in my case, not yet, however, I was just reading quite an exciting article about a man's endeavors to create a rake that could set the chisel pins in a Medeco lock to their proper orientation, and he has had some success. Some of the big dogs here even chimed in with useful ideas and info. I'll link you.
