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 tanto is a celebratory dagger made in the Muromachi period, also known as an "iwaizashi". It is engraved with a Chiyotsuru inscription, a school of swordsmiths that flourished from the Nanbokucho period to the Muromachi period. The hamon has a mixture of gnome and choji in the midare, with some yo and tama visible, and the nie is well tightened.
