Odd object found a new use, but what is it?
My grandpa has upgraded his dolly with this spoon like object he's had in his possession for decades. The hole in the top is threaded, he said there was a threaded rod like object that was in it previously that you could twist and the rod would go in and out of the scoop - big nail for demonstration purposes. He really wants to know what this was for originally, any ideas?
