Handcuffs

Handcuffs are hand binding objects made of metal that are used in the Boiling Rock prison. The guards use the handcuffs to restrain the new arrivals of the prison, so they can transport them to their cells without harm.

A less contemporary version of handcuffs was seen in Winter Solstice Part 1: The Spirit World, when Iroh got captured by Earth Kingdom soldiers. There have many dangling chains attached to the cuffs, and they restrain the prisoner's entire body rather than just their hands. Iroh attempted to escape by tricking the guards into touching the cuffs, which he heated with Firebending, but to no avail. He later fought the soldiers with the broken chains of the cuffs.

The more current version of handcuffs was seen in The Boiling Rock, Part 2, where all the new prisoners, including Hakoda, exiting from the gondola wore them. After Hakoda refused to look The Warden of the prison in the eye, The Warden knocked him to the ground by kicking down his handcuffs. Hakoda gave in, but still had the courage to trip The Warden with his handcuffs while he was walking away.

Later on that day, Sokka, Zuko, Suki, Hakoda, and Chit Sang were escaping from the prison on the gondola. Princess Azula and Ty Lee arrived just at the right time to fight. Azula, not having the capabilities Ty Lee did to run on a thin rope, grabbed a pair of handcuffs from a guard nearby, propelled herself into the air with Firebending, and then used the handcuffs to hook on to the gondola's line, where she then propelled herself along the rope until she made it to the gondola. Once there, she disposed of the handcuffs.
