GERMAN CUSTOMS STOPPED THIS ONE EVEN THOUGH SIMILAR ITEMS ARE AVAILABLE.

These high security, nickel plated, hinged handcuffs are the top of the Clejuso range.  The lock is a 'Yale' type tumbler lock which is virtually unpickable.  The key can be inserted or removed in one of two positions.  In the first position the handcuff if locked, the second, about 45 degrees clockwise, the handcuff is single locked and ready for use on a prisoner.  Turn the key another 45 degrees and the handcuff is unlocked.  These handcuffs weigh 900 grams.
