Previous answer is
Tanba no Kami Yoshimichi (First Generation)
丹波守吉道(初代)

Features: Kyo-Tanba 1st generation’s sword is very rare. His father
is Kanemichi of Mino school. They moved to Kyo and
started the school. It was continued to 5th generation
but the 1st worked on in short term so his sword is rare.
This sword has some Machiokuri but wide and Hamon is
seems like the proto type of Sudare, the original and
popular Hamon of the school. Hamon on both side is
different. The 1st generation’s sword is really rare, we
strongly recommend you this sword.
