8. (Julia K. Murray, 1982) The blade F1917.30 is unusual in having two sharpened edges which meet at right angles. From the placement of the two perforations and the beveling of the long edge, it seems possible that the blade was originally intended as a jade replica of the horizontal harvesting knife (see the large knife that was excavated at Erh li t'ou [Erlitou] 二里頭, Yen shih [Yanshi] 偃師, Honan [Henan] 河南 from Early Shang 商 remains; in Robert W. Bagley, "The Beginnings of the Bronze Age: The Erlitou Culture Period," in The Great Bronze Age of China: An Exhibition from The People's Republic of China, ed. Wen Fong (New York: Metropolitan Museum of Art, 1980), cat. 3. If so, then the blade broke and was refinished by beveling the broken short end to a sharp edge, like an axe. (For a general discussion of jade axes, see Folder Sheet F1918.35.) This explanation is tentative, however. A similar piece is in the Chicago Art Institute (1950.312, reproduced in Alfred Salmony, Archaic Chinese Jades from the Edward and Louise B. Sonnenschein Collection [Chicago: Art Institute of Chicago, 1952], pl. XXVI:3).
