Hal. That beautiful stone was used by the ancients to braid hair. It's likely Woodland and quite nice. It was fully oblong and whole at one time. I suspect the lady of the house caught her man out with the neighbors sweetie and ultimately broke it over his head whilst he ran for the door. It's perfectly flat on one side and that tells me she was working the blade on her knife for a later meeting with her future her x- husband. Sounds reasonable to me. What do you think?
ATLATL WEIGHT . . . THATS EXACTLY WHAT IT IS...Tks Brad.
I Googled "atlatl weight" and found several different documented designs and this triangular design was one of them. I did not see the exact groove configuration but that must have been an individual option.
I'll still keep it with the cherished gorgets and properly labeled.
