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 signed by Yoshimitsu from the Tosa province, active around the Eisho era (1504-). It features a hira-zukuri construction with an exceptionally thick kasane, characteristic of a Yoroi-doshi (armor-piercing dagger). The blade comes with an NBTHK Hozon certificate and is accompanied by a black-lacquered Natane-Nuri Saya Aikuchi Tanto Koshirae and a gold-foiled Habaki in Shirasaya.
