\nThe kissaki is slightly elongated, and the curvature is shallow, giving the blade an appearance suggestive of excellent cutting ability.
\nJigane: Beautifully forged and well-refined ko-itame hada.
\nHamon: The hamon begins with suguha at the hamachi and develops into choji-midare farther along the blade.

Features: Yamato no Kami Yasumichi was a swordsmith of Mino Province active around the Kanbun era (1661\u20131673).
\nHe belonged to the Akasaka Senjuin lineage and also forged swords in Owari Province.
\nThis blade is an exceptionally fine example of his workmanship, displaying an impressive Ichimonji-style hamon.
\nThe temper pattern from the hamachi to the middle of the blade is particularly well executed.
\nBeyond this point, the hamon rises high enough to reach the shinogi-ji.
\nThe boshi is almost ichimai in appearance, with a rounded turnback.<\/p>\n

Aoi Art\u2019s Comment: This is an exceptionally well-forged blade featuring a beautifully executed Ichimonji-style choji hamon.
\nBoth the hamon and jigane are of excellent quality.
\nMasame hada can also be observed in the shinogi-ji.<\/p>\n

Historical Background: As Japan transitioned from the Muromachi period to the Edo period, the shape of Japanese swords underwent significant changes.
\nThe characteristic Kanbun Shinto style emerged, featuring relatively shallow curvature and an elongated kissaki.
\nIn Mino Province, the production of tanto declined dramatically as demand for these short blades diminished.
\nSwordsmiths increasingly shifted their attention to the production of katana and wakizashi.
\nIt was during this period that swordsmiths attempted to reproduce the magnificent Ichimonji-style hamon of earlier times.
\nThis particular blade demonstrates remarkable skill in achieving that style.
\nSwordsmiths of the period likely had to adapt to changing circumstances and seek out locations where they could continue their craft and earn a living.
\nYasumichi appears to have been one such craftsman, producing outstanding swords while responding to the demands of his time.<\/p>\n
