The B-Lock is a real functioning padlock. You even get the key attached with a piece of string so you can’t lose it. So why is it then when you try to put the key in the lock it won’t go?
Before you can use this padlock to lock up your stuff you need to solve the puzzle first! And all the tools you need to open the lock have been provided with the puzzle.

But once you know it’s secret you can safely use the lock to keep things safe. For sure no-one else will be able to unlock it…. or is that UnBlock it?

It may not be quite as hard as his father’s famous Danlock but don’t underestimate this puzzle. There’s a real Aha! moment once you manage to UnBLock your mind and you come to the solution.

This puzzle lock is designed and made by Boaz Feldman. B-Locks are made from real padlocks made by Nabob in Israel that Boaz has precision machined into this unique puzzle lock.
Size: 64mm x 43mm x 13mm
Packaged in a felt bag with a printed solution enclosed.

It seems that designing and making puzzle locks runs in the Feldman family. Boaz’s father Dan is famous for the mechanical puzzle masterpiece that is the Danlock (also available here at Mr Puzzle) and Boaz has now taken on the mantle to keep creating it.

    Nice addition to lock puzzle family...

    This is an intermediate puzzle between the DanLock and the FunLock.
    There is a journey of discovery involved.
    Again it feels nice and solid.
    Initially it is perplexing. Then a few “A-ha” moments later, it is open.
    Often arriving at the solution initially is almost by accident.
    However with repeated puzzling, the elegant solution is finally realised.
    Have fun!
