Interesting comment that the flexible chain tends to eat cutting discs.
You can buy those disc lock picks on E-Bay for cheap, although his video about picking the Kryptonite NY indicated that he had issues with depth, I think, which may have led to making the custom pick.
Apparently the Lock Picking Lawyer has struck out trying to pick the Bowley Lock.

Odd the LPL didn't choose the Bowley + a robust chain.
