An Australian stone tool type, a symmetrical leaf-shaped point, up to 7 cm long, unifacially flaked all over its dorsal surface. The striking platform and bulb of percussion are sometimes removed to produce a rounded, thinned butt. Pirri points have been found distributed widely in inland Australia from South Australia to the Northern Territory and northwestern Australia. A component of the Australian Small Tool Tradition, the Pirri point dates from about 3000 BC. The aboriginal term pirri means 'wood-engraving tool'.
