The age known for its use of tools and weapons from flint and stone was know as

I don’t think this will help but anyhow here is some more info if u need any

"Novaculite" is a metamorphic rock that is similar to flint. It has a sedimentary origin, just like flint, but diagenesis and metamorphism have increased the size of the quartz microcrystals. It has been used for thousands of years for making sharp tools and weapons.

Hope this helps...

i think its the stone age because they were inventive in this period of time?

" the stone age -a prehistoric period when weapons and tools were made of stone or of organic materials such as bone, wood, or horn."

"Flint was used in the manufacture of tools during the Stone Age as it splits into thin, sharp splinters called flakes or blades (depending on the shape) when struck by another hard object (such as a hammerstone made of another material). This process is referred to as knapping."

hope this helps :)
