B-Lock is an original lock puzzle, designed by Boaz Feldman (the son of Dan Feldman, the designer of the DanLock).

B-Lock is a two stages puzzle. When you first examine the lock, you'll notice that you can't actually insert the key into the keyhole... It's BLOCKed! To unlock it, you'll really need to think outside the box. The specific trick of this lock puzzle is like nothing you've seen before. A Eureka moment is promised for the solver.

B-Lock is made of brass and stainless steel, based on a standard lock.

Package contains the lock, a fabric bag and an instruction card.

"It is truly a surprising and delightfully sneaky puzzle lock." - Boxes and Booze

"I marvel at the incredible machining skills that Boaz has developed to carry out that incredible modification with such subtlety." - Kevin Sadler, PuzzleMad

"It is an instant classic: a fun puzzle to solve with some sublime machining and excellent camouflage…" - Allard Walker, Puzzling Times
