Toph's bracelet

Toph's Bracelet is a small piece of meteorite that Toph wears around her arm like a bracelet. It is a leftover piece of the meteorite that Sokka used to forge his sword. He gave it to Toph, thinking that she might like the opportunity to bend "space earth". She can bend it into any shape she wants, including a star, a spiral, a key for picking locks and comically, the Nickelodeon logo.
