The raw material for other categories of artefacts is a variety of fine-grained sandstone. The edged tools are made by flaking and grinding. That the tools were manufactured at the site is indicated by the grinding stones and chips found at the site. Technologically they fall into three main groups: (1) flake tools represented by a solitary example of a thin leaf-shaped flake of indurated shale, (2) edge-ground tools, represented by four specimens on sandstone made wholly by flaking and finished by grinding at the cutting edge, and (3) fully ground tools, forming the majority of the tools found in the excavations shaped by very fine flaking and finished by grinding all over the surface and edge. The tanged or shouldered celts and the quadrangular adzes with flat sides were also made by this process. There is no sign of sawing by metal wire of any tool. The majority of the stone tools is small in size, the length varying between 2·9 and 5·9 cm. In some cases the breadth of the tool is greater than the length, an unusual feature resulting from frequent resharpening. - [Previous: v2.c31.107](https://indike.org/pramana/ins.reference.ghosh-1989.v2.c31.107) - [Next: v2.c31.109](https://indike.org/pramana/ins.reference.ghosh-1989.v2.c31.109) - [Up: v2.c31](https://indike.org/pramana/ins.reference.ghosh-1989.v2.c31) --- Source: [https://indike.org/pramana/ins.reference.ghosh-1989.v2.c31.108](https://indike.org/pramana/ins.reference.ghosh-1989.v2.c31.108) · Pramāṇa
