This is a mythology weapon persay that is like a gigantic fist but instead of it being a fist, it's something that extends further than your fist. You grasp it in your hands from the handle that is smooth and rounded. Once gripped, there's an extending pallet looking thing that you'd use to thrust into your enemies. It was said to weigh 1000's of pounds and only able to be wielded by Thor himself.
