[Source] Mandalorian vambraces were devices designed to combat the abilities of a Jedi. The Mandalorian Fenn Rau gave a pair of Mandalorian vambraces to Sabine Wren in 2 BBY. They came equipped with a repulsor, grappling line, paralyzing darts, a shield emitter, paired blaster barrels, and a flamethrower. The Mandalorians developed these vambraces alongside their armor as a reaction to the Jedi's Force abilities encountered during the Mandalorian-Jedi War.
