Introducing a breathtaking Tanto by the renowned Uda Kunitsugu. A pristine piece, this blade also boasts a distinct groove (hi) which further accentuates its beauty. Kunitsugu is a well-recognized master craftsman from the Uda school, famously known as the offspring of Kunifusa. This sword embodies the refined artistry and skill of Japan during the Muromachi period.

About Kunitsugu: The Uda school traces its origins to Kunimitsu and thrived during the Nanboku-chō period with swordsmiths like Kunifusa, Kunimune, and Kunitsugu, extending its influence into the Muromachi period. According to inscriptions, Kunitsugu was the younger brother of Kunimitsu. Historically, swords from the early Kunitsugu, dating back to the Embun era, are rare finds. This particular blade is believed to be crafted by the Kunitsugu who is passed down as the child of Kunifusa, and from its inscriptions, it is discerned to be one of the oldest known works from around the Eikyō period (circa 1429).
