tennessee artifacts? Help identify these if you will, please, thanks

Can anyone tell if these are artifacts or not.

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?
