Here is a typical Bizen-den traditionally made Katana by an accomplished sword artisan Yokoyama Toshi-saemon-no-jo SUKEKANE 横山俊左衛門尉祐包.
In the 8th month of Tensho 19 (1591) Koto Muromachi period, a flood struck Fukuoka-sho, Osafune area as a result of localized downpour, most of sword workshops were carried away by the flood and SUKESADA aterier 祐定 was no exception.
One of the founder Yokoyama Souzaemon SUKESADA 横山宗左衛門祐定 reconstructed SUKESADA 祐定 atelier in Shinto period along with his brothers Shichibei-no-jo SUKESADA 七兵衛尉家 and Genzaemon-no-jo 源左衛門尉家. Those three SUKESADA families had been prospered throuhgout Shinto Edo period.

The subject swordsmith Yokoyama Toshi-saemon-no-jo SUKEKANE 横山俊左衛門尉祐包 was an adopted son of 横山祐盛 who was a legitimate son of Yokoyama SUKEHIRA 横山祐平 who belonged to Yokoyama Souzaemon SUKESADA lineage 横山宗左衛門祐定.
He is distinguished as the final doyen of Bizen sword smiths in Shin-shin-to period along with his uncle SUKENAGA 祐永.
Both SUKENAGA 祐永 and SUKEKANE 祐包 were exclisively worked for Bizen domain and they sometimes inscribe proundly in Nakago as A 56th or 58th-generation descendant of TOMONARI.
His extant works with the date of year ranged from Tenpo 6 to Meiji 5 (1835-1872) in the last years of Edo period. He belonged to pure Bizen-den technique and devote himself to restore the antient work of founder in Osafune TOMONARI in kamakura period. He is very good at the hamon of "Jyuka-Choji midare" which looks like the row on row of clove flower buds and succesfully revived Bizen-den technique in Shin-shin-to period.

The subject katana is designed for suitabilily in shape and deep in Sori that reminds Tachi of ancient Kamakura Osafune works. Further flamboyant hamon nearly reaches to Shinogi-ridge and is superior to the other examples in abundant activity of hardening boundary line.
