Houdinis Handcuffs, Chrome with Padlocks by DF

This is so convincing to your audience. Your wrists are tightly secured to the ends of a long metal shackle by means of two heavy duty chains and locks. Escape seems impossible, but nothing is impossible in the world of magic. All can be examined. Locks not supplied, use any padlock or combo lock. Advertise that you will escape from locks brought in by the audiance!
