Looks to be a sweet chopper, love the material and the way it looks. Maybe they started to take flakes off to make it something other than a chopper but then they realized it was too perfect as a chopper, hahaha. I have found some similar looking made out of chert cobble in Austin, TX... That's a large one. I can see the indention so the palm or hand will fit in comfortably. Ask yourself, does it fit to the hand well enough to make work simple. Nice find...
