What are the representative forms and tools of labor behavior in primitive society?

The tools of labor in primitive times were stone tools.

It is speculated that in the process of human formation, when natural sticks and stones were used for food and defense for a long time, it was found that it was more labor-saving to cut things with the sharp edges produced by gravel crushing, so I was inspired to hit the stones and break them to make suitable tools. The most primitive way to make stone tools in Paleolithic Age was to strike or hit a stone to form a cutting edge, that is, to make a thin-edged stone tool for cutting. In the Neolithic Age, stone tools manufacturing technology has made great progress. First of all, there are certain requirements for the selection, cutting, grinding, drilling and carving of stone materials. After the stone is selected, the prototype of the stone tool is made first, and then the blade or the whole surface is placed on the stone and polished with water and sand, which becomes a ground stone tool.
