Composite Sickles and Cereal Harvesting Methods at 23,000-Years-Old Ohalo II, Israel

Fig 6

Artifact AJ39c with micrograph of the semi-ripe cereal polish and hafting wear: a: a reticular pattern with a relatively high degree of linkage between the polished surfaces (x100); b: streaks of dull rough polish associated with slight edge rounding interpreted to be produced by the contact with a haft (x100); c: reticular polish cut by the break indicating that the blade was broken after use (x100); d: linked and smooth polish developed on elevated points (x100); e: rough thin polish observed away from the developed linked polish fading gradually at the inner surface of the blade (x100).
