Hello,
Back in 1983, my grandparents found a rock that is on the Pictures.
Today they showed me it, because they wondered what it is. They supposed it was used in the ancient times by the old People to chop the skin from Animals.
If any of you guys can help me, I would be really happy.
I have these from collection I bought. When image searching several results that mentioned stone age tools had very similar pictures. I assume it would take someone much more intelligent then me to make correct assertion.
They have a glass like sound when tapped together, a clanging sound...
