Really unique find. Looks like to have been completed 50-60% then discarded for some reason. Thinking it was going to be a Frio or San Patrice type many? Thoughts?
Not familiar with native american spoke-shaves. I guess this could be a possibility . So I am assuming a right half of a point would not be fashioned in this way?
I am not familiar with knapping technique, just an observation on what this looks like.
I am with zim on this one, it's a good sized spoke shave. What appears to be a notch, could possibly be a smaller spoke shave, or just incidental. It doesn't appear to have been a halfted tool imho.
