I agree with some of opinion and I toss in rock garden but some I don't ex stone knife has at least eight man Marks at least four around back core another the square black tool I posted all eight corners polished the same angle this was not done by mother nature I do post questionable stones because not sure and then I like to post my views on to get you to look at my findings ex flare bit Celt I posted as tool it has rubbing marks on sides but nothing on top or bottom I have been hunting artifacts for 42 years and I'm still learning I try to use James Bennett and Lar hothem books on authenticating artifacts what to look for also when there is multiple stones with same shape mother nature does not do this ex the axe I posted the white one this paloe or early archaic I know of in collections even Harrisburg museum with same shape and construction this what I based my opinion on and the stone knife the same form found in area I really do like opinions but not when posted rock only it should be explained why you see rock only this is a forum I was informed on this site I am not allowed to post my opinion because the opinion given to me is by someone smarter then me this post will probably black list me from getting opinions also opinions based off photographs which is hard with artifacts easier when in hand thank you for reading my OPINION
