Actually I did, I found a piece of obsidian that was turned in to a little knife/hide scaper, I've been looking everywhere for it. and if you notice the hide scraper that I posted clearly shows working marks.. It may not look like it but it's an old piece.. My area is not tools of flint napping.. these are made from a glacier that settled, strong hard rock. I haven't seen hardly any flint in this area. It may not look like it but a lot of these are much older and brittle than they seem. For example the hide scraper in the pic above.. if I soaked it in water for two long and took the brush to it I would lose all the marking. of course not all of them are of such but a lot are. I personally don't think that all of these are artifacts.. a lot of them have notches. The fact of the matter is that I posted 3 artifacts that I have already gotten authenticated, And no one has said anything about them. That just proves to me that no matter how long you you've been doing this it doesn't mean you know it all because you obviously don't. And that right there is facts! We all learn something new everyday.. well.. Some of us do that is., lol
