One of my great uncles had a small collection of sharks teeth that somehow managed to find its way into our household. I’ve posted a photo of a sharks tooth from that collection in the past. This quartz arrowhead was in the same box. I don’t know where it was found although my guess would be North Carolina. I don’t even know for sure that it was found by him, but I assume it was. It’s a beautiful little thing. I’ve never really tried my hand at knapping stone but I would guess that quartz is not the easiest material to shape. If it’s all you have, however, I guess you’d learn and obviously someone did.
