Power wrench

"Aaaaaaaaahhh! What are you doing?! Remove the arc wrench, remove the arc wrench! Medic!"

―HK-47 to Revan, after Revan failed to access his memory core

A power wrench was a tool presumably similar in use to a hydrospanner. In 3956 BBY, Revan used a presumably similar tool called an arc wrench to try to access HK-47's memory core. Luke Skywalker kept a power wrench in the garage of the Lars homestead on Tatooine, and used it for repair work on his T-16 skyhopper. In 8 ABY Chewbacca used power wrench for taking out old sensor array window when working on Millennium Falcon.
