What is this
Hi, I know some one who found a large or huge pestle looking object that's about 15 inches and has rounded bottom. However, this pestle looking thing had about a 5 inch hole drilled through it going down the shaft. What could this be and used for? Also it weighs about 17 lbs. and the hole through the center is perfectly round and goes down the shaft. Stone looks to be a type of granite.
