The evidence from the Bulgarian Early Neolithic chipped stone industry reveals coherent and diagnostic flint assemblages for the vast Karanovo I and II cultural area, characterized by high quality yellow-honey coloured flint, quite long and regular blades, with (bi)lateral semi-abrupt high retouch and sometimes with rounded or pointed ends, as well as highly (re-)used sickle inserts. These assemblages possess many characteristics of so-called ‘formal tools’ (as distinct from expedient ones), the production of which required a special raw material, advanced preparation, anticipated use, and transportability. The wide geographical distribution and circulation of this formal toolkit implies that lithics could be conceived as a factor in identity and social cohesion, and as an important aspect of the Neolithic mentality for ‘doing things’.
