- "Well that's not it. Bring me the hydrospanner!"
- ―Han Solo
A hydrospanner was a tool that could be used to repair starships.
During the Clone Wars, Anakin Skywalker used a hydrospanner while repairing the Twilight. Several years later during the Galactic Civil War, Han Solo asked Chewbacca to bring him a hydrospanner when he was working on the Millennium Falcon.
