A staff was a stick or rod that could be used to assist a being in walking or as melee weapon which could be use for offense or self-defense. A staff could also be a symbol of office or serve as a religious icon.
During the days of the Galactic Republic, the Senate Vice Chair to the Supreme Chancellor carried the Speaker's staff as a symbol of their office. Mas Amedda held the position during the final days of the Republic.
During the Clone Wars, various forms of electrostaff were used by both the IG-100 MagnaGuards of the Confederacy of Independent Systems and clone shock troopers of the Coruscant Guard. Shortly after the First Battle of Geonosis, a clone trooper named Cut Lawquane deserted the Grand Army of the Republic and settled as a farmer on Saleucami. He made use a staff with rounded loop with three spikes at one end which he could use both as a farm tool and weapon with equal skill.
