Those stone implements were used by Stone humans.
They are heavy for human use.
When Stone humans caught deer, they held Tokko stone and blew the nose of it and gave the deer to humanity for food.
Hammers were also used for the same purpose.
Stone bars and flat stones seem to have been used for flaying or tanning the skin by Stone humans, who made humanity use the small ones after teaching how to use them.
