Unusual Artefacts Identified ?

Copper Flaking Baton heads in net on right.

The flattened end was placed on the "stone" and the baton
which would have had a wood handle insert, was struck ,
and a piece of stone (flake) would be struck off.

I was told to look for a "smushed - up" end , and that's
what I see. Sure has been a long time finding out the use.
Thank you Tony Romano for recognizing its use from an old
artist's painting of early American Culture. Many have been
found in the Lake Superior region since Bill Ross was trying
to identify ours in the 1970's.
