Short description: Flint-tool fabrication technology
The Helwan retouch was a bifacial microlithic flint-tool fabrication technology characteristic of the Early Natufian culture in the Levant, a region in the Eastern Mediterranean (12,500 BP – 11,000 BP) such as the Harifian culture.[1]:172-3 The decline of the Helwan Retouch was largely replaced by the "backing" technique and coincided with the emergence of microburin methods, which involved snapping bladelets on an anvil.[2][1]:172-3 Natufian lithic technology throughout the usage of the Helwan Retouch was dominated by lunate-shaped lithics, such as picks and axes[1]:167 and especially sickles (which were predominantly—at least 80% of the time—used for harvesting wild cereals).[3]
