Era Nanbokucho Period
Shape: The previous attribution was to the lineage of Nagayoshi, but it is now believed to be a disciple　of Chikakuni. The abundance of large-sized swords during the Nanbokucho period reflects the　turbulent historical background of that era.
Jigane: Well-forged, finely textured itame hada with a hint of mokume hada.
Hamon: A prominent midare (irregular) hamon with abundant ashi (feet), sand patterns (sunagashi), and fine nie (martensitic crystals). The boshi (temper pattern at the tip) is irregular
with two lines of nie.

Characteristics: The previous attribution was to the lineage of Nagayoshi, but it is now believed　to be a disciple of Chikakuni. The abundance of large-sized swords during the Nanbokucho
period reflects the turbulent historical background of that era.

From Aoi Art: This blade is undoubtedly a work from the Nanbokucho period. It displays a　strong hamon with clear activities, including sunagashi and close nie. The condition of the tang　is excellent, and with further polishing, this piece could become quite significant. Regardless, it is　undoubtedly a remarkable piece and one I highly recommend.
Historical Context: The Nanbokucho period was characterized by battles on horseback, resulting　in a prevalence of longer swords.
