Certificate
【Description】
Summary
This blade is attributed to Higo Daijyo Sadakuni (肥後大掾貞国), who was active in sword-forging during the Keicho era (
1596-1615: Early Edo Period
) in Echizen province (today’s Fukui prefecture). He belonged to Echizen Shimosaka School, one of the most prestigious schools in the province during the Edo period. He was a prominent figure in this school. It is said that he was a younger brother of the first-gen Yasutsugu, the founder of the school. And, Sadakuni was the teacher of Kotetsu (虎徹) in terms of Horimono technique(Engraving on the blades). Daijyo was an official rank only given to highly skilled swordsmiths back then.
About Echizen Shimosaka School
It is said that the first-gen Yasutsugu was the founder of the Echizen Shimoasaka school. He was born in Shimosaka town in Shiga prefecture at the end of the Muromachi period(Late 16 century ). He built his career there until the beginning of the Keicho era(1596). However, he moved to Echizen province due to the relocation of the lord he served. He eventually was noticed and supported by Matsudaira Hideyasu, the third son of Tokugawa Ieyasu, who was the founder of the Edo government. Hideysu was the feudal lord of Echizen province during the early Edo period.
With the support of Hideyasu, the first-gen Yasutsugu was able to establish the Echizen Shimosaka school. And his school’s fame became nationwide.
By Hideyasu’s recommendation, the first-gen Yasutsugu became Okakaekaji for the Tokugawa shogun family, meaning that he exclusively forged swords for the Shogun family. Yasutsu was acknowledged by the first and second Tokugawa Shoguns, Tokugawa Ieyasu, and Tokugawa Hidetada.
The first-gen Yasutsugu received 康(YASU) from Tokugawa Ieyasu and changed his maker’s name. He was also allowed to inscribe the holly oak symbol(family crest of Tokugawa) on the tang. The school flourished during the Edo period and trained many skilled apprentices. Sadakuni was one of the most famous apprentices among many swordsmiths who resided in Echizen province.
About Echizen province
Echizen Province was famous for forging razor-sharp, practically designed swords. The Edo government, run by the Tokugawa clan, ordered many blades from the swordsmiths in this province during the Edo period(1603-1868). There were so many swordsmiths in Echizen province, originally from the Mino province(Gifu prefecture), which is known as one of the five great Japanese sword styles MINO-DEN.
