\nHamon: Suguha hamon with a tightly defined pattern, differing from the workmanship typically seen in Tadayoshi blades.

Features: Although this sword has an NBTHK Tokubetsu Kicho Token certificate, I have doubts about its authenticity.
\nUnfortunately, I cannot recognize the signature as genuine.
\nTherefore, this sword is being offered for sale as gimei (false signature).<\/p>\n

Koshirae:
\nTsuba: A mokko-shaped iron tsuba carved with a wave and plover (nami-chidori) design, decorated with gold iroe.
\nNBTHK Tokubetsu Kicho Tosogu: Mumei (Attributed to Shoami Katsuyoshi).

Aoi Art\u2019s Comment: This is a long katana with a blade length exceeding 2 shaku 4 sun, accompanied by an impressive and beautifully crafted koshirae.
\nThe sword is very well made, but I believe its hamon and jigane differ from those normally associated with Hizen no Kuni Tadayoshi.<\/p>\n

NBTHK Tokubetsu Kicho Token.
\nTsuba: NBTHK Tokubetsu Kicho Tosogu.
