The drilling of tools with grinded stones is a technique often applied during Late Prehistory. The two prevalent methods of drilling of the time are suggested mainly by unfinished artefacts. The first method, simple and extremely time-consuming, was already in use from the Upper Palaeolithic period on less hard materials (antlers, teeth, shells) and comprised the piercing of the object with a hard pyritic stone (e.g. pyrites, quartz). The second method, which is the subject of this article, is more complicated and requires substantial “technical backup”, since its “technological chain” includes a multitude of auxiliary implements. However, the basic implement is the tubular drill. In context of this experimental approach, the drilling of various kinds of stone was attempted using pieces of reed, which is a par excellence “pyritic” plant, meaning a hard plant.
