Together with other discoveries, this spear-like sharp-pointed tool arrived at Bryansk Regional Ethnography Museum in 1975. Fyodor Zavernyayev determined the approximate age of this item: from 100 to 120 thousand years. It was made in the times of Middle Paleolithic. This period is also called Mousterian because of the name of the cave Le Moustier in France, where the items of this epoch were discovered for the first time.

The scientists determined the age of the discovery based on the traces of treatment on its surface: in those days, people polished and sharpened stones bottom-up (in earlier periods they did it vice versa). This sharp-pointed tool circa 23 cm long was carved out of a unitary block of silicon. Then its edges were sharpened using a bone or a wooden tool, and its edges were slightly polished. The scientists usually call such treatment “retouch”. Such sharp-pointed tools were tied to wooden handles with stripes of leather to make their use easier for chopping or cutting.

Fyodor Zavernyayev assumed that this stone piece was used as a spearhead. However, it also could be used for other purposes: the sharp edges easily cut meat, veins and skins, and the sharp point could be used to make holes in wood, bones and soft stones. During hunting, people could use such tools instead of knives.
