The blacksmith lineage Yoshimichi 吉道 originates from the Mishina 三品 school of Mino, founded by Kaneuji 兼氏 at the 14^th century. This school was strongly influenced by the tradition of Soshu because Kaneuji was one of the ten students of Masamune. The Yoshimichi lineages of the Shinto era are very reputed and known for the invention of the Hamon Sudareba 簾刃 taking up the pattern of bamboo curtains, made from Sunagashi.

The blade presented is a realisation of the first works of Tamba No Kami Yoshimichi from Kyoto 2^th generation. The second generation of Kyoto was the brother of the 1^era generation of Yoshimichi from Osaka, both sons of Yoshimichi 1^st generation of Kyoto.
Kyo Yoshimichi 2^nd bore the civil name of Mishina Toshichiro (三品藤七郎) and received the title of ‘Tamba No Kami’ in 1639, as well as permission to engrave the 16-petalled imperial chrysanthemum. He was the first of the line to have this right to engrave the Kiku. He was known for his hamon Sudare Ba and developed the hamon Kikusui (Chrysanthemum on water).

The Mishina school 三品 was imported from Seki (Mino) to Kyoto by Kanemichi 兼道 (9^th gen Kaneuji) in 1593, with its 4 sons, Iga no Kami Kinmichi (伊賀守金道), Echigo No Kami Rai Kinmichi (越後守来金道), Tanba no Kami Yoshimichi (丹波守吉道), Etchu no Kami Etshi (越中守正俊).

This Mishina school from Kyoto, is characterized in 4 main streams, Kyo Tamba No Kami, Osaka Tamba No Kami, Fushimi Tamba No Kami, and Yamato No Kami. These schools strongly influenced the Japanese forge at the beginning of the Edo period.
As said above, the most well-known of Kanemichi’s blacksmith sons is Tamba No Kami Yoshimichi 1^st Gen of Kyoto, who created the magnificent hamon Sudareba based on superposition of Sunagashi lines parallel to the edge.
