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 is a Tanto by Masashige from the mid to late Muromachi period. It features a robust hirazukuri body with a well-forged ko-itame hada and a suguha-cho hamon with fine sunagashi. The tanto comes with a koshirae featuring a black shibukawa-nuri saya and charming kappa menuki on the tsuka, reflecting ancient beliefs in water deities.
