Uda Long Black WAKIZASHI, KOTO Muromachi period, with Certificate

Muromachi period Uda.
This is a long Wakizashi, and the Hamon appears to be in the Suguha style at first glance, but on closer inspection it is interestingly varied.

The Uda were a group of swordsmiths active in Ecchu (present-day Toyama prefecture).
Their roots lie in the Yamato School.
They migrated from Yamato to Ecchu at the end of the Kamakura period, and continued to thrive until the Muromachi period.

Comes with an NBTHK Certificate.
