Lanvarok
From Wookieepedia, the Star Wars wiki.
Lanvarok was an ancient weapon that existed in two varieties: the Sith lanvarok, and the Massassi lanvarok. The Sith lanvarok was a wrist-mounted projectile launcher that could fire a volley of metal discs, usually in a small but unpredictable spray pattern, which makes dodging or blocking the deadly projectiles very difficult. A more primitive Massassi lanvarok was a two-handed polearm that required brute strength rather than mechanical action or the Force to launch the disks.
