Sengoku Seki was an industry: smiths organized under their tutelary Kasuga shrine, arming the war bands of central Japan. Magoroku Kanemoto’s sanbonsugi and the finest Kanesada work prove quality survived inside mass production.
This katana is by Izumi no Kami Kanesada, also known as Nosada, a representative swordsmith of Mino during the Sengoku period. It is a masterpiece imitating the strength of Ko-Teagai Kanenaga, made shortly after Kanesada began signing with the 'Nosada' character. The blade features a robust masame-hada from the Yamato tradition, with a hamon of suguha mixed with kuichigai-ba and strong inazuma, showing great vigor. This long blade is a rare and exceptional work by Nosada, incorporating the strong nie of the Yamato tradition.
