Shape:The blade has a slightly wide mihaba (width), a slightly deep curvature, and an extended kissaki, giving it an elegant shape.
Jigane (Steel Surface):The ko-itame hada is well-forged, resulting in an excellent steel texture.
Hamon (Temper Line):It starts as a straight hamon from the hamachi, then transitions into a tight nioiguchi gunome and choji.
The nioiguchi is well-closed, forming a flamboyant Yokoyama choji-midare.
The boshi turns back in a rounded manner.

Features:This sword comes with our evaluation certificate.
However, based on our assessment, it may receive a “hold” judgment at the Token Museum.
The Kurashiki certificate states that this blade is a product of a workshop and likely made by a disciple.
I share the same judgment.
Formally, it should have the “Kikumon Ichi” engraving.
Therefore, it cannot be definitively classified as a counterfeit.

Koshirae:
Tsuba: Mokko-shaped iron tsuba with openwork carving of a plum blossom and bamboo leaves.
Fuchi: iron plate carved with a ear of rice.
Menuki: a picture of a chiken.
