Yari is the Japanese pronunciation of 槍, the Chinese character for "spear". The spearhead alone is usually just simply called yari as well.
Cross-sections vary, but usually are triangular with often a groove on the largest of three flat sides.
The yari has been in general use since ancient times, but became increasingly popular form the Muromachi period (1336-1573) onwards and were used by simple soldiers and samurai alike.
A rare form of yari with kusabi-hi.
