This point type is very difficult to identify. The first thing that really stands out, is that it is a re-sharpened version of a once larger point, and not much way to tell if the original point was barbed or not. Thats about as much as I can figure.
Yes, that could further describe a re-sharpened point. I'd say that the point in it's original form was considerably longer (lancolate form), and whatever it was/is, could be transitional paleo to early archaic in age. This one has been resharpened all the way down to the top of the base.
