The only (as far as I know) working Sodan staff weapon from Stargate SG-1 and one of the few working staff weapons. It is made of resin, is 1.3 meters long and weighs about 2.4kg. Being the last iteration of the Goa'uld staff weapons (it made it's appearance in the 9th season), it's the most complex design, using batteries and a servo motor for operation.
