Dr. Hester had commented on the nine that I posted here, only three are beveled. #6 is flat on the back side, not even worked, so that's where the confusion starts. Some of my Kinney's also have thinning flakes at the base, one was even incorrectly, I think, called a fluted Kinney. Two of the three with beveling are local, the third from the hill country, some 100+ miles apart. Beveling nearly all but one type, is from re-sharpening, so where's the beveled Kinney's? I don't have one.
I remember when you first posted that one G-town. Those serrations and color are the giveaway. None of mine have serrations. Seems like the basic triangle shaped point is the most common anywhere. Simplest of designs.
That's what makes it hard to seperate the different types. Mabbe not so when digging with a clear line of demarcation, but when surface hunting, everybody is just laying out in the sun on top of the ground. Thousands of years of history with no separation.
