NihontoWatchThis katana is a collaborative work by the father-son smiths Seishinshi Nagatoshi and Sadatoshi, both renowned for their cutting ability. Nagatoshi, born in 1901, was certified as an Important Intangible Cultural Property holder of Tokushima Prefecture in 1974, and Sadatoshi, born in 1929, inherited the 'Seishinshi' title. The blade features a well-forged Itame hada, a Gunome hamon with Choji, and a strong tang with a collaborative signature.

Shōwa to the present: destruction and revival
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.
