What were the most ancient tools of labor? what kind of work can they do?

The oldest wooden tool of labor can be considered a stick, with the help of which roots were dug out of the ground, and it could be protected from a predator. But modern monkeys can use a stick to knock down the fruit, as well as when defending when attacking it.

But the first conscious tool made of stone was a chopper. With its help, it was possible to break fruits, crush bones in order to get bone marrow (by the way, a favorite delicacy of our distant ancestors). With his help, they hunted and defended themselves. They were made on the spot and were not carried with them during migrations. The first choppers date back to the Olduvai period, about 2-1.5 million years ago.

Scrapers. They cleaned animal skins from fat.

Plates. Incisors. A kind of prototype knives. With their help, they cut the skin, cut the grass.
