The cores are of a type typical for Harappan culture, both conical and elongated. The blades have been struck off with the pressure technique. This involves pressing the surface of a flint or flake with a soft-pointed instrument. In Europe, the soft points were made of red deer antlers. In Rohri they were almost certainly made of copper. Such points are usually 3 to 3 cm long, and 3-4 mm thick. No example has yet been found in the Hills.
Here the surface of a workshop and three sub-conical cores are visible.
