My partner found this one. I believe this one actually came from upstate New York. It is exactly the same on the other side and the left side in the picture is rounded like it was used as a scraper. The right side is sharp. I'll grab some more photos of this one today.
Thank you so much. That's what we were thinking. I guess I should start digging out arrowheads and my collections of flint, obsidian and I have some unusual Mahogany Obsidian.
