This must be Rainer's pride and joy! In par with DanLock (if not better) in my opinion.
I broke down and looked at the solution for this puzzle, in fear of damaging the puzzle if I continued. Boy do I regret doing that.. I would probably still be working on it if I hadn't looked.
These locks ain't cheap, but they are milled from a solid block (you could probably kill someone with it judging by the weight =) and are hand crafted.
