Hard to tell from the pics, sorry. Try posting them one at a time, just too many to ID at one time. Also give shots from all sides. Good Luck!

No expert at all but I am pretty sure top row/far right and first pic in 3rd row (same piece I assume...)Was used to strip/straiten arrow shafts. Someone correct me if I am wrong but I am about 90% sure that is what it is....Hope this helps..

Natural geo facts. They all look like they should be something but are not. Did you find any flint flakes with them?
