Knife-shaped blade

This is a large elongated chip of irregular subtriangular shape. One end of it is broken. One edge of a chip is straight, slightly curved. The item is covered with small chips, probably from use. The second edge is convex, with virtually no damage or traces of processing. The edges form a rounded thin end. Negatives of earlier large chips remain on the surface. This object could be used as a tool, such as a knife.
It has a functional purpose: blank for a tool or a tool itself.
It is a typical object of the Paleolithic era in Eurasia.
