The tool of ancient man of the II–I millennia BC is an exhibit with losses: one side has a large chip. The pest is in the form of a cone with a cut-off top and, somewhat polished by friction, a working plane.

A pestle (terochnik) is a stone tool used for grinding or pounding any substances: minerals, paints, medicinal plants and more. Also called the upper stone of the grain grinder.

Stone pestles were also used for processing other stone products or buildings by grinding and grinding them. They were made of various breeds and had different shapes: flat discs, rounded and others.

Often, ordinary pebbles served as the grater, on which the worn-out areas remained. They are most characteristic of Neolithic, Eneolithic and Bronze Age settlements.
