Mullet, I meant that I created the flake which became the arrowhead with a hammer stone by striking my large cobble (don't know the official term). I then used antler tines to flake it. And that's good to know about the size, thanks. I'm going to haft it soon! I thought it might've been too small to even qualify as a "bird point" based on the ones I'd seen in the encyclopedia.
And thanks for the ID help everyone, that's very interesting. ill post a picture soon.
Also thanks Le0n, I'll try the bi polar split and take it from there.
