Backed edge bladelet

On a blade of a regular shape with slightly convex edges, there was made a microlithic tool - the insert of a larger composite tool. One edge on the face, covered with a lime crust, has been almost completely backed by an abrupt, not very even retouch. The other edge, sharper one, has only small chips, most likely - the result of use. Both edges are linear, but there is no regular retouching. This blade could be used as an insert for a composite tool, where it would be fixed in a groove or the split end of a shaft. The functional purpose of this blade is to be used as part of a composite tool. It is a common find at sites from the Upper Paleolithic period in Eurasia.
