I ask men all the time about my "finds" and unless it's a "named" shape of a bifacial, expertly worked, perfect condition "point" or other weapon, they say "It's a jfr" which I take to mean just a flippin rock. Men don't seem to get that people had to do things besides kill stuff, and so needed differently shaped tools and gadgets to do those things. The most obvious one is "make fire". If you can hold the curved stones firmly in your fingers and they have a hook on them, it is likely a fire starter, which when scraped against pyrite made a spark to ignite the tinder, to light the fire, to cook the stuff the stupid men killed, and so they could tell their stupid hunting/war stories. I'm interested to know if the ones you found had the shape of a bird scratched into them, like mine have.
Also, shine a light on each piece in a dimly lit room and look for pictures made by the shadows of carvings that might not be noticeable to the naked eye. I have seen many cool stones that have wonderful pictures in them, perhaps for illustrating the stupid stories told by the stupid men around the fire we started with your finds!
