No I haven't, see my previous post. I have submitted that the arrowhead was either designed to perform a different function(shoot smaller game), the design was not completely thought out, the design used the materials on hand, or is a pretty paperweight.
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?
