Tanto - Nobukuni - NBTHK Kicho Certificate - Shirasaya Koshirae - Ubu Nakago - Koto Era - Oita 32774

¥280,000

A dynamic short sword with a single-beveled blade, certified by the National Board of Swords Appraisal (NBTHK), is recommended for you.

The blade has an antique polish but is in sound condition with almost no flaws. The blade thickness is 8mm, giving it a robust construction reminiscent of Yoroidoshi. The jigane displays a mixed itame and mokume grain pattern, with yubashiri clearly visible. The hamon is a fine, tightly drawn suguha. The blade's appearance evokes the bold style reminiscent of Kikuchi-yari. Kikuchi-yari refers to a straight spear created by attaching a short sword blade to the tip of a long shaft. It originates from an improvised weapon devised by Kikuchi Takeshige during the Nanbokucho period at the Battle of Hakone-Takenoshita.

The nakago is inscribed with the name Nobukuni. Nobukuni belonged to a school that dominated Kyoto for a time and is said to have been a disciple of the Ryokai school. This school of swordsmiths expanded nationwide from around 1356 until the Meiji period, shifting their primary forging regions over time. They were active in Kyoto from around 1400 to 1440, in Buzen from around 1440 to 1600, and from around 1600 until the Meiji period in Chikuzen, Chikugo, Bungo, Higo, and other regions.

In May 1968, the Society for the Preservation of Japanese Art Swords certified this work as being by Chikugen Nobukuni, issuing an authentication certificate. It is equipped with a well-preserved white scabbard.
