Researchers in China have examined denticulate tools found at Peiligang sites which show signs they were used for agricultural purposes, these specific tools are referred to as 'denticulate sickles'. Denticulate sickles are characterised by a denticulated cutting edge with grooves carved into it and a concave back opposite to grooves, one end of the tool is pointed and the other has a notch where a wooden handle may have once been connected. These tools can range in size from 10–20 cm and are made from soft lithic materials. Usewear analysis of these tools suggests they were used for harvesting cereals, cutting grass and reeds and stripping fruits and nuts from branches. However, findings concluded that "denticulate sickles were multi-purpose tools, rather than specialised implements for harvesting cereals."
