Vambraces

A wore a pair of golden weighted appendages around his arms that closely resemble vambraces . He uses these braces both as a training tool and an offensive weapon in battle as they have protrusions that can jut out. The left one was burned to ashes by Sasuke 's Amaterasu , along with A's forearm. Since the start of the Fourth Shinobi World War , he has stopped wearing them.
