There are indeed blunt arrowheads used for small game, and there are known samples of these. When you provided the sample of a known arrowhead, did you provide a sample of the kind of arrowhead you believe this is?
Don't blame me, this was your specification.
I said "known to be an arrowhead". There are rocks we have already established to be arrowheads. Get me one of those.
I had no functional concept in mind. I just thought that it was an arrowhead fashioned by intelligence. I did not say a small game arrowhead fashioned by intelligence.
