I picked this piece up from Kinley Coyan at the Fredricksburg knap-in. He picks it up off of his ranch. He puts a little heat to it and WOW it is some good stuff. One of the easiest stones to knap. It doesn't take a lot of force to make it work. Here are some pics of the reduction stages. I need to straighten the sides a little but Ill save that for another day.
