I found this website listed today...
Stone Age Skill Site
It focuses on stone age stuff and skills.
Some parts were rather interesting in the .pdf articles.
For example, testing to see what kind of rocks are the best for immersion in water, rather than other which crack.
I really like the images of the different color stones. Personally, I prefer the colors of less expensive stones, to diamonds and emeralds.
These stone-age guys were definitely into function more than glitter.
Sounds like tree workers and their chainsaws.
