The adze is made of volcanic tuff of fine texture with a smooth polish, imparting a surface sheen similar to that of jades.
The large adze has a sharp rectangular cross-section with a step to the upper part. It has a long sloping cutting edge to the lower front, with a shorter cutting edge on the reverse, and was made as a specialised wood tool.
The quality of stone and finishing of the current adze are both exemplary. The cutting edges are remarkably sharp and the adze does not appear to have been used or suffered from any damages, it is very likely that it was used as an important ritual implement. The current adze dates to Liangzhu Culture or slightly later.
