Hello Gents
Has anyone come across this type of Hamon before, It repeats itself every 10 inches, they have one the same in the Victoria and albert museum with a fake UMETADA MYOJU mei, and mine has a fake Tamba no kami Yoshimichi mei. The rest of its characteristics resembles gendai Yokohama school. I have owned this sword for 20 years now, and have found nothing in any books I have, appart from the one below.
Any clues?
