This unsigned katana measures 65.1 cm (25.6 in.) in blade length with a graceful 0.8 cm sori. The blade has undergone ō-suriage (major shortening), a feature commonly seen on earlier Japanese swords that were remounted and adapted for later generations of use.
The blade displays a well-forged itame-hada with a refined suguha hamon formed primarily in nioi, producing a bright and consistent temper line that extends smoothly throughout the blade. The overall workmanship reflects a practical yet elegant style favored for battlefield swords.
Based on its sugata, substantial shortening, and forging characteristics, the blade is most likely attributable to the late Muromachi period (16th century), although an early Momoyama (Keichō) date cannot be entirely ruled out. The restrained suguha and robust construction are reminiscent of the workmanship associated with the Mino tradition and other provincial schools producing functional swords during Japan's turbulent Sengoku era.
The sword is mounted in an Imperial Japanese Navy officer Kaigunto mounts.
