I have a long-held point in my collection with a very similar base--Jerry Dickey called it a Thebes on the COA (this one hasn't ever been sent for papers)--but I view both that point and this very wide based point as Big Sandy Broadbase points--easy to see Jerry's viewpoint, but I'm still not convinced either one is a Thebes. Yes, the time frame for each point goes back to the extremely early part of the Early Archaic, but the configuration of the base (side notches, not lobes), and the blade edge sharpening style, quadra-facial, not bevel sharpening, those two factors convince me to classify this (and the COA point) as "Broad Base" styles, Your opinion may lean the other way--that's what opinions are--and should be. This point comes from a creek hunter in Webster County, Kentucky, it's made of a VERY high grade of Kentucky Sonora Flint,2&5/8" by a wide 1&11/16"==5/16" max thickness. The basal edge shows very heavy edge grinding. There is some wear on the very tip, but then anyone who looks at this blade and doesn't account for many, many sharpenings of the cutting edge is (honestly) fooling themselves if they think this wasn't a heavily used knife. Tools got used, period. Shipping is $7.00, checks or M.O.s are how I take in payments--I do not use paypal (or its clones)--Roy A.
