Special feature: Gassan Sadakatsu was born as the second son
of the First Gassan Sadakazu in 1869. Sadakatsu was a representative swordsmith of Taisho to early Showa period. He was an amazing swordsmith to make all of Soshu-den, Bizen-den and Yamato-den. Especially his distinctive Ayasugi-hada inherits the tradition that has been continued from the Kamakura period still lives on in gendai swordsmiths. Under his famous father Sadakazu the First, Sadakatsu forged only a few swords inscribed his swordsmith name until the death of Sadakazu in the late Taisho era. Sadakatsu put all his energies into making his own sword after 1920’s as a purveyor to the Imperial Household, special swords to dedicate the Ise-Jingu shrine, accepting orders by high dignitaries. He tempered sword with sincere and faithful attitude in conformity with Shintoism. Under that he trained many excellent swordsmiths. His two most excellent pupils, one was his real son the Second Gassan Sadakazu and the other was Takahashi Sadatsugu, were designated as preservers of Important Intangible Cultural Assets, popularly known as Living National Treasures. Sadakatsu passed away in 1943, aged 74. This work has Gassan(Ayasugi)hada and very difficult to get recently. Gassan Sadakatsu was the most well-known swordsmith from the Taisho to the Showa period. The most excellent point about him is that he was good at all styles like Soshuden, Bizenden, Yamatoden, and Yamashiroden. Gassan school has succeeded in recreating Ayasugihada, that was once lost. This production method is classified as strictly confidential and succeeded to today. This blade is a masterpiece we can see Ayasugihada directly.
From Aoi Art: Gassan Sadakatsu had to have made this blade very elaborately, especially for a man whose name is Miyoshi Tokumatsu. Miyoshi Tokumatsu ran a mine in Fukuoka prefecture. He started with a member of the village assembly, and finally was elected as a member of the House of Representatives. Unfortunately, he passed away only 5 months after this blade was finished. We can see the hidden Ayasugihada under well-made Jigane. Hand writing by Gassan Sadakatsu and gold-foiled single Habaki: we easily know that they thought that the money is no object. We truly recommend this rare piece of art to you.
