Wristband blades
Wrist-blades, also known as wristband blades or retractable wrist blades, were ejectable vibroblades that were mounted on gauntlets.
These wristband blades consisted of jagged vibroblades, several centimeters in length, housed in a linear arrangement along the gauntlet. A prominent instance of their use was by Jango Fett during his battle against Obi-Wan on Kamino. He deployed them to prevent himself from plummeting off the landing platform where they were engaged in combat.
Furthermore, protocol droids that had been modified for use as gladiator droids aboard the Wheel were also outfitted with these wrist blades.
