Well defined balance point.
Regardless of size, the majority of the tools I find have a well defined balance point. I believe this could have been done to facilitate hafting. However due to the wear patterns I see on these pieces I do not believe that many of these tools were normally hafted but because of the well defined balance point they could have been if needed in a hurry.
This next shape is very common and looks similar to the letter P. The two common features you will see on this shape are pecking marks where there is the obvious removal of material and a well defined balance point in the same location.
Both the small piece in my hand and the much larger piece on the ground have similar tool marks in the same areas and a very well defined balance point in the same area.
