Gear Shredder

The Gear Shredder is one of the technologically simpler weapons used on Cybertron. It fires out razor-sharp spinning blades that bounce off walls and will cut right through an enemy. It can be also charged up to fire three blades at once, letting you slice and dice the foe when they come at you in groups.

Gear Shredders were used in the closing days of the Great War between the Decepticons and the Autobots.
