I picked up a large gravel cobble at the companies dirt pit yesterday. They are everywhere out there. This piece had 3 percussion flakes taken from one side. I picked up my spalling billet to try the stone out. It knapped like glass. I made a rough preform yesterday, & finished it today. This stone was outstanding. I cant imagine why the stone was never finished eons ago. I'm happy with the was this point turned out with raw stone. I hope y'all enjoy. Tower
