What are the three main types of stone tools in Paleolithic Age?

The main stone tools are still the same: stone axe, spear and chisel.

Early Paleolithic Age: At this time, the stone tools were relatively simple. Generally, natural gravel was knocked and then slightly processed. Stone tools are irregular in shape, but they have many uses.

Middle Paleolithic Age: At this time, the stone tools were more complicated, the beating technology was greatly improved, and the processing was more refined.

Late Paleolithic Age: At this time, the stone tools have appeared perforation and polishing technology.

In the middle of the Paleolithic period, represented by Moster culture, it was mainly characterized by the great development of stone core repair technology (Levalova technology and disc stone core technology), and the typical objects were exquisite scrapers and sharp objects.

Extended data type

Kitchen knife: it is made of stone chips, stone cores or gravel, which is big and heavy.

Scraper: It is made of small stones. Common stone tools in Paleolithic cultural sites in China.

Pointer: the top has a sharp edge, which is often machined and trimmed twice.

Carver: It's made of small stones. First, make an inclined plane on the edge of the small stone piece, and then stagger an angle to hit another stone piece. The intersection of two stone marks is the blade of the device.

Axe-shaped tools: mostly stone core tools made by double-sided repair. There is a blade at one end and a hand-held handle at the other end.

Molding machine: formed by pressing. Its sharp edge tends to lean to one side.

Knife-shaped device: the stone piece is thicker on one side and looks like the back of a knife.

Stone spheroid: also known as "stone core tool", it is an irregular sphere, and the whole body has been processed and trimmed, and there are obvious peeling scars on the sphere.
