Crushgaunt

Crushgaunts, also called shuk'orok in Mando'a, were a type of strength-enhancing gauntlets created by the Mandalorians centuries before the Clone Wars. They were made of a reactive, polymer-enhanced material reinforced by beskar plates. They could increase their wearer's grip strength to the point that they could shatter bones, crush durasteel, and deflect weapons, even lightsaber blades. Captain Phasma wore a pair of crushgaunts as part of her armor.
