A very rare dagger has just arrived. This tanto is a celebratory dagger made in the Muromachi period and called "iwaizashi," and is a rare piece that is rarely found on the market. It was made as a gift for celebratory occasions and was very auspicious, and this piece is engraved with a chiyotsuru inscription. Chiyotsuru is a school of swordsmiths that flourished from the Nanbokucho period to the Muromachi period (1336-1573), also known as the Echizen Rai school, because it was founded by Chiyotsuru Kuniyasu, a member of the Rai Kuniyasu school, who migrated to the Echizen region. Since the crane (tsuru) has been a symbol of good fortune in Japan since ancient times, it is believed that they asked Chiyotsuru, which means crane that lives a thousand years, to create a celebratory dagger.

The sword is very well preserved for its age, and is virtually flawless. The hamon also has a mixture of gnome and choji in the midare, with some yo and tama visible, and the nie is well tightened.

Please add this very nice and auspicious heirloom dagger to your collection.
