I thought it was just a mechanical tool but Chewie is so frantic to fix the Hyperdrive he has caused electricity to arc to it (I hope it's got an insulated handle otherwise the smell of cooked Wookiee hair will take weeks to clear).
With the reflection thing drawn out like that it's hard to debate it, sometimes eyeball Mk 1 is not enough (unless the eyeball is really good).
Shame because it does look good even if it is a few frames but that isn't enough to justify the work.
