Very cool. It makes you wonder if it was ever hafted or if the damage occurred when shooting. Being such an exacting thing to create such a fine piece, I could imagine the power could have been lost when a portion broke away. The creator tossing it aside to begin again. I once watch my mother, having spent hours working on one of her magnificent baskets only to have her approach the fireplace and toss it in. It seems there was a flaw that I hadn't noticed that she was not comfortable with. Perfection is like that. However, It is just as likely to have broken anytime after creation as it is obviously delicately made. I have a few fine pieces that I broke during recovery, made me slow down just a bit. Nice find.
