DanLock - A sequential discovery lock puzzle, brain teaser for adults, gift for dad, complex trick lock, gift for engineers, birthday gift.
DanLock was originally crafted in 1996 by Dan Feldman. This lock is your best pick if you are always on the lookout for a new challenge to stimulate your mind, and was declared by many as "The best puzzle lock".
As DanLocks riddle goes, it is more like three locks packed in one - a complete "escape room".
DanLock contains two keys - the first one is secured by the shackle and the second one is, unfortunately.... broken.
Will you be able to open it? Will you be able to bring it back to its original state?
DanLock is made of brass and stainless steel, based on a standard lock.
The package contains the lock, a fabric bag, and an instruction card.
