T12 is a fairly old design. Actually it should become T8. But then I came up with the actual T8 and had to do this first... :-) T12 is something like an "old fashioned" trick lock. No unusual Tricks and movements, but overall quite challenging and rewarding I guess.
The lock has 10 steps to open, according to the manual.
