PicoLock is a lock puzzle by renowned maker Boaz Feldman. AS usual the padlock comes with a key but you can probably guess that it doesn’t work.
Several things stand out about the PicoLock, you’ll find a small hole on one side and on the other the shackle seems to go all the way down to the bottom.
Made from a standard padlock Boaz describes the mechanism as unique and not one found in any other lock puzzle.
PicoLock is a small lock and measures roughly 40mm wide. It comes with a fabric bag, and instruction card.
