A little dirt on a field find, I generally don't wash the point--just picture it as the finder left the piece (patina)...but when the point is just plain muddy, okay, it's time for a bit of light scrubbing. The piece is from a Vanderburgh County, Indiana, collection--going strictly on the Indiana Harrison County-type hornstone, it's most likely a local find--or possibly in Henderson County, Kentucky, hornstone of that type heavily dominated the flints used in this area. As you move farther west, Early Archaic Culture's "Kirk Culture" knappers might use a different flint source, similar, but slightly different in color. Length is slightly over 1&7/8", that tip nick taking off the length that would have pushed the length over 2". Width is 1&7/16", slightly shortened due to one barb end being dinged. I don't sell used cars, you get a 'damage report' on anything I sell: basic honesty. Now, that bifurcated base, that's some fine, fine workmanship, fluted on both faces, and super thin in the center of the auriculate base--thinning must have been VERY important to the Kirk hunter. So--you see the "before pics" and the "after wash" pics--you see what I see: authenticity. Shipping is $8.00, checks or M.O.s are how I welcome payment. Sorry, I do not use paypal-type payment services--Roy A.
