The term (classification) of Fractured Base Dovetail seems to have originated with Red Tully, or at least that was the first use of the term I learned in his book on point typology, but he had extensive point & collecting experience--I still use some of the things I learned from him. If you could listen past his constant 'growl', you learned something--you also learned of his demand for authenticity. I respect that. Okay, this field-found Dovetail comes from a Dubois County, Indiana, farm collection--or at least I assume all the family's points came from their farm--Indiana Hornstone, 2&3/4" by 1&5/16" with a 7/16" thick blade--both faces are fairly flat, heavily, heavily bevel sharpened. One side shows the field soil--wash it if you want, I'll mail-out the piece exactly as I got it--I like the patina this way, I see which side was rain washed, which side was face down. One barb is modern nicked--plow damage as thee isn't patination of the flint (with time). The base shows exceedingly heavy basal edge grinding--and those corner 'fractures' like a Decatur (hence the 'fractured base Dovetail' name). The tip shows a darker hornstone, but whether that means there was some 'later period use', or was there an inclusion of much darker gray flint exposed when the tip underwent Early Archaic sharpening, that's impossible to say. Under a 10x loop you can study the study how the long, flat tip flake starts out weathered, but gets darker as you reach the very tip. To me, that indicates an inclusion in the flint. That's how I judge the color change. The Dove is guaranteed authentic, ancient, in every detail. Shipping is $8.00 with checks or M.O.s how I welcome payments.
