This handcuff is very special. Probably, as far as I know, these are the only produced magnetic locked handcuffs in the world. It was built in the 1970s and the bow is only connected to one side of the cuff. You must put the magnet in the big hole to lift the metal plate which locks the handcuff and opens them. Because this was impractical, the cuff wasn't produced long. Alltogether, the lock is very simpel, you also don't have a doublelock. Also, most of the handcuffs were destroyed as an order from the government. So, they are really rare today. My magnet isn't the original one, but a magnet you find a lot with this handcuff type.
