The twentieth century nearly killed the craft twice: wartime distortion, then the occupation ban. The NBTHK’s founding in 1948 and licensed forging from 1953 rebuilt the sword as an art, crowned by Living National Treasures and the mukansa rank.
It has appeared, it has appeared! A masterpiece tanto forged with the popular, family-tradition Ayasugi-hada by the Living National Treasure Gassan Sadakazu, a name far too famous in the world of swords. In Showa 41, Gassan Sadakazu succeeded to the name of his grandfather, the Imperial Court Artist Gassan Sadakazu. In Showa 46, he became the third swordsmith to be designated as a Living National Treasure after the war, following Takahashi Sadatsugu and Miyairi Akihira. Due to the nine-year ban on Japanese sword production by the occupation forces following Japan's defeat in the war, the extant works of the Living National Treasure Gassan Sadakazu are extremely few, and he is known to the world as a smith of phantom masterpieces. This tanto is a precious work forged with the family-tradition Ayasugi-hada in Showa 48, two years after his designation as a Living National Treasure, a time when his creative will was at its peak and his masterpieces were born. The sugata of this tanto features a shin-no-mune, with a difference between the moto-mihaba and saki-mihaba, presenting an elegant tanto form without sori. The jigane is the Gassan family tradition, forged in the rare and precious Ayasugi-hada, and it is magnificent. The hamon is a nioi-deki with nie-attached notare-midare-ba, interlacing with the Ayasugi-hada of the jihada, and the hataraki within the blade is also superb. The client, Mr. Nagano, is a businessman, and the current owner has entrusted us with this piece, saying, "We have grown old, so please pass this precious Ayasugi-hada tanto to someone who will cherish it." Therefore, we are offering this masterpiece tanto forged in Ayasugi-hada by the Living National Treasure Gassan Sadakazu at a special, low price. Please by all means enjoy this famous tanto forged with the ancient and famous Ayasugi-hada by the phantom Living National Treasure Gassan Sadakazu.
