Authentic Nihontō Japanese Sword Katana Attributed to Mihara Masanobu 三原正信 NBTHK TOKUBETSU HOZON TOKEN Certificate

In Bingo, where it is said that Yamato swordsmiths relocated from the early Kamakura period, the Yamato tradition was followed without influence from neighboring Bizen. Masaiye, the founder of the Bingo Mihara school, displayed craftsmanship akin to Yamato Kanehisa. 

Mihara Masanobu, classified among the early Mihara school swordsmiths, was active from the Nanbokucho period Enryaku (1381) through the early Muromachi period Meitoku (1390). His son moved from Mihara to Tomo, becoming the founder of the Tomo Mihara school.

This sword has a hada mixed with itame and mokume, showing some flowing patterns with a slightly prominent grain. While it appears to have a simple suguha at first glance, closer inspection reveals fine activities within the hamon, such as nie extending to the blade's interior, subtle waviness, and interplay of itame and mokume. The piece demonstrates a sophisticated ancient aesthetic distinct from later Mihara works, with abundant hamon activity and a desirable length of over 71 cm.

Currently, it features a wooden habaki with the same tsuka, so it would be ideal to craft a new habaki, finish it up, and challenge for an Important Sword designation. 

Bare weight: 600 grams.
