Droid shock arm
From Wookieepedia, the Star Wars wiki.
The Droid shock arm was an upgraded droid utility item that delivered a jolt of electricity to an unsuspecting victim. This device had been popular for utility droids since it was easily hidden among the droid's other tools.
[edit] History
A shock arm was included on T3-M4, a T3-series utility droid, in the days of the Jedi Civil War. Shock arms were also incorporated thousands of years later on many models of astromech droids. R2-D2 and R4-P17 were two astromechs known to have shock arms.
[edit] Behind the scenes
In the game KOTOR II, only T3-M4 is capable of equipping this item.
