Rare Tenerian Culture Green Sahara, Neolithic BEAD GROOVER/Axe Polisher 155
BEAD GROOVER-AXE/ADZE Polisher
Tenerian Culture, c. 7500 - 5300 B.C found in an exposed site in the South Central Sahara, Tenera Region, of The Green Sahara, which was when Northern Africa was covered by grass, trees, and lakes.
Size: 8.7cm wide
During the Neolithic era, craftspeople fashioned beads from materials such as stone, bone, shell, and clay using specialized tools called grooved abraders or polishers. These tools featured one or more grooves on their surfaces, which developed either through repeated use or careful shaping of beads and also for reworking the edge of an adze or axe.
Makers usually selected coarse, iron-rich sandstones for these abraders, as their gritty quality made them ideal for smoothing and shaping other substances.
Shape: Most grooved abraders were plain, irregular stone pieces, generally small (5–10 cm), with the main distinguishing feature being their worked grooves.
Grooves came in various profiles—some V-shaped, others more rounded—and differed in depth and width. A single tool might have multiple grooves, each serving a different stage of bead production, from initial shaping to final polishing.
Bead makers would move unfinished beads, which were often already drilled with tiny flint tools, back and forth in the grooves. Water and gritty powders like agate dust were sometimes added to help wear down and polish the surface more efficiently.
These abraders were essential to the widespread bead-making traditions that developed in the Neolithic Near East, Europe, and Africa.
