One of the better Late Archaic (2500BP) Stemmed points I've held in-hand--either Indiana Hornstone or possibly a 'look-alike' grade of our Indiana Holland Chalcedony---in some lights it looks like hornstone, Holland (Spencer County, Indiana chert) in other lighting. I wasn't told this was a creek find, but that may account for the 'toning' of the flint itself. Being Late Archaic Culture, there is no grinding on the base of the stem, only slight-to-moderate dulling (grinding) on the sides of the stem. Assuming this was a hafted knife that was almost a guaranteed cut-through-the sinew with repeated use--but then I'm second-guessing some hunter 2500--3500 years ago. They had their reasons for so little dulling on the stem. Length is an excellent 3&1/16" by nearly 1&5/16", the well fashioned blade is 5/16" thick. There had to be multiple sharpen and use cycles as one blade edge is almost beveled--notice how it curves-in slightly, tip-to-barb--that would indicate the more "used" side of the knife. Great patina, excellent knapping work, guaranteed authentic in every detail. Shipping is $8.00 with checks or M.O>s welcomed. Sorry, I do not use paypal-type payment services--Roy A.
