Tammy, I showed you Stone Tools in the top post. I have lots of Stone Tools including Axes, Celts, Pestles, Hoes, etc and yours is not an Axe. I have studied your pictures very closely and there is no evidence whatsoever that was ever used as an Axe. It has no blade on it at all and it shows no use wear, no battering from being used, and no polish from extended use. No disrespect to your friend but he is obviously clueless. Can you post pictures of his collection? I'm curious to see what he actually calls an Axe or and Stone Tool.
This will be my last attempt at this. These are all Axes, Celts, Pestles, and Hoes. All show pecking, grinding, blade edges, polish etc from manufacture and use. If you can't see the difference in these pieces and yours and see that yours is not an Axe then I am done.
