Apparently I get along much better with copper tools when they're pre-tarnished. It bugs me to see bright spots where the metal hasn't been rubbed, but for whatever reason, accumulated tarnish in those same unreachable spots "looks right" in my mind. So this is what I've come up with.
Over time the fresh scuff marks will blend-in and the finish will become more uniform, but the finish looks great as-is too.
EDIT: Just for the heck of it, here's a pic showing the light when it was brand-new.
