Anybody know what this is? It was in the back in the cubby under the floor of the rear hatch when I picked up my new Model S 100D a month ago. Didn't lift the cubby cover when I inspected the car at delivery center, so I didn't notice this sitting in there until I got home. Very heavy metal, 14" long, looks brand new as zero scrapes or other indications it has been used as a tool in manufacturing or anything like that.
