Description

Yosōzaemon Sukesada (1467-1542) was one of many smiths of the village Osafune in Bizen who signed their work with Sukesada (祐定). Yosōzaemon however was regarded as the best smith, not only of his school but quite possibly of Japan at the time. He was mainly active in the early 1500s, with extant swords dating to mainly the Eishō (永正, 1504-1521) and Daiei (大永, 1521-1528) periods.

Fujishiro Matsuo rated his works sai jō saku (最上作), the highest possible classification reserved for grand masters, and Yamada Asaemon V ranked Yosozaemon's swords as ō-wazamono for extreme sharpness.

He was the son of Hikobei no Jō Sukesada (彦兵衛尉祐定), a master swordsmith in his own right and together with his son the two top smiths of Bizen at the time.

 

Working style

Yosōzaemon primarily made uchigatana and some tanto. He mainly worked in the Sue-Bizen style, what made him stand apart was his superior forging of a fine and tight mokume and itame hada.

He tempered in a nioi-based hamon in suguha, gunome-midare-choji and more flamboyant, hitatsura style tempering. He is thought to have pioneered the so-called kani no tsume (), “crab claw” hamon seen in the below photo.

Crab claw hamon

Yosōzaemon's signature "crab claw" hamon.

The steel tends to looks bright and silvery with ji nie that may form chikei. Sometimes faint utsuri can be present. The boshi is a continuation of the hamon, often different on both sides, and usually with a deep kaeri.

 

"His kitae is considered to be the best of his time, so when considering a piece that is extremely well forged, with otherwise typical Sue Bizen characteristics, Yosozaemon should come to mind."

A peculiar feature of his work is that he finished his tangs with a rounded back near the base of the blade, flattening out near the tip.
