The visible sign on stone tools that were used for harvesting plants is called, “sickle sheen.” Stone tools used to cut meat don’t have the sheen. Pretty cool article. Thanks for posting it.
KingLudd has had an avocational interest in stone tool replication and flintkanpping for almost 30 years. I’m hoping this early technology gets popular again. Until then, Spyderco.
You may get your wish with the collapse right around the corner.
Happy knapping!
My pleasure.
