Bone implements, the only examples of which come from the caves in Kurnool, were made on elongated strips taken out of long bones, which can be termed as bone blanks. To produce the latter the epiphyseal ends of the long bones were first cleared off either by chopping or by percussion flaking. On these prepared-to-size shafts parallel grooves were made along the long axis and bone blanks were removed by splitting along these grooves. Bone blanks were also made by vertical flaking on the external surface of a longitudinally cut bone. They were finally finished into various forms by lateral chipping, pressure flaking, oblique flaking and vertical flaking, and the working edge was ground in some cases. The working ends on some of the perforators were also fire-hardened.
