Muromachi turned sword making into an industry: the uchigatana rose with massed infantry warfare, Osafune and Seki produced bundle swords beside custom orders, and the Ming trade carried Japanese blades abroad by the tens of thousands.
This antique Japanese Katana was signed by Kanetsuji during the late Muromachi period in Mino province. He was a Sue-Seki smith, known for the practical and innovative designs of the MINO-DEN school. The blade features exquisite 'Hataboko' engravings and is stored in a Tachi Koshirae, appraised with an NBTHK Hozon Certificate.
