[Source] Cortosis gauntlets were arm braces made with cortosis ore woven into them. Acting as protective shielding, the gauntlets were used by warriors who engaged in lightsaber combat. As cortosis was a naturally lightsaber-resistant metal, when the blade of lightsabers came into contact with the gauntlet, the blade would short out for several minutes. During the Clone Wars, Jedi Master Micah Giiett owned a cortosis vambrace, and used it to educate padawans about lightsaber-resistant materials. Anzati assassin Sajé Tasha wore a pair of clawed cortosis gauntlets during the Clone Wars.
