This is an Omiyari (large spear) by Sanjyo Yoshinori, a representative smith of the Muromachi period in Kyoto. It features a hira-sankaku-zukuri shape with a normal body width and an extended kera-kubi, typical of spears from that era. The jigane is well-forged ko-itame-hada with fine ji-nie and chi-kei, while the hamon is suguha-cho with shallow notare-gokoro, ko-ashi, ko-nie, kinsuji, and sunagashi.

The Heianjō school (平安城) of swordsmiths represents the principal lineage of Kyōto sword production during the Muromachi period. "Heianjō" is the classical name for Kyōto (Heian-kyō), and the school's smiths — resident in the Sanjō district of the capital — signed variously with the 平安城 (Heianjō) and 三条 (Sanjō) prefixes, a usage that has often caused them to be confused with the far earlier Sanjō school of Munechika.
