77701--Hornstone Big Sandy, high end point

A Warrick County, Indiana, find, nice, very patinated piece of Indiana Harrison County-type Hornstone, 3&1/4" by 1&1/4"--VERY good length, and a max thickness of only 5/16", so the 'balance' is there, too. The width insside the basal notches is closer to the "E-notch form" of the Big Sandy than a standard or even Broad Base Big Sandy--one side, the base is more than a square notch, it hooks upward--that, I's why I type the Early Archaic point as an E-notch. Interesting features in the construction of the piece--the blade is beveled on only one face, both edges; the reverse isn't flat, but it's not far from it. You can take from that that there were a considerable number of ancient sharpenings. One other feature that doesn't seem to have an explanation is that the basal edge is NOT ground--deliberately not ground. Answering that "Why", when it's a rarity for Early Archaic points in general to have ground bases--why isn't this one? The piece is 100% guaranteed authentic, the patina is there, but I can't explain that basal edge--next artifact show I see Jerry Dickey I'll get his thoughts on the subject--I respect his opinions. Shipping is included with the price, checks or M.O>s are welcomed. Sorry, I do not use paypal--Roy A.
