Interesting, they don't show the pick but apparently every time he withdraws the bolt another little way, he has to change some bit on that tool.
I do not know what is inside this lock, but the key is double bitted, lever type.
That the bolts only withdraw a certain distance for ever turn of the key is interesting,
It would be interesting to see photos of the lock case opened and the bolts and levers showing. Also a photo of the pick would be interesting.
I noticed his technique is a sort of loose tryout thing, no real pressure steadily applied.
bring us more on this thing.
