The celadon jade is well-polished, carved to a broad, thin rectangular blade tapering to where the point is formed, with notched flanges along its back, its surface deftly incised with a stylised cloud pattern. With a conical hole drilled through the tang.

青白玉，體扁平，琢成長方形刀，往上漸收而成刀鋒，沿刀背陰刻了古雅的雲雷紋，刀背外部則琢有一排齒稜。刀柄中央鑽有一圓孔。應為祭禮用器。
