A grooved rock (likely made of large-grained material like sandstone), pastoralists, and the Ju/'hoansi (for abrading), arrow shaft straightener (a versatile tool)

A grooved rock, likely made of large-grained material (required for abrasion) like sandstone. 'Uses included the production of cylindrical bone tools; straightening of arrow shafts; shaping of strung ostrich eggshell rough-outs, shell and bone beads; and even the careful application of arrow poison to cylindrical arrows' (Boeyens in Boeyens et al., 2017: 20).
