The Legend of Kogarasumaru — The Divine Sword of the Imperial Collection

The Kogarasumaru (Little Crow) is one of the most legendary swords in Japanese history — a unique blade that combines the features of a tachi (long sword) and a tanto (short sword), with a double-edged tip (kissaki) on both sides of the blade. This unusual design is found on no other Japanese sword, making the Kogarasumara truly one of a kind. According to legend, it was forged by Amakuni, the legendary swordsmith said to have invented the curved Japanese sword, and gifted by the sun goddess Amaterasu to the Taira clan as a symbol of divine favor and martial authority. The Taira clan used it as their clan treasure for generations, until it eventually passed into the possession of the Japanese Imperial family, where it remains today as a national treasure. The Kokarasuma is inspired by this extraordinary legacy.

T10 Carbon Steel — One of the Finest Blade Steels

T10 carbon steel (approximately 1.0% carbon content) is one of the finest steels for sword-making — its high carbon content providing exceptional hardness and edge retention. T10 is the steel of choice for premium Japanese-style swords, offering performance that approaches the legendary tamahagane steel of traditional Japanese swordsmithing. The T10 blade is hand-polished with a collector edge and full tang — an authentic sword as well as a collector piece.

Burnt Blade Finish — The Aged Appearance of a Legendary Sword

The burnt blade finish creates a distinctive dark, textured surface that evokes the aged, battle-worn appearance of a legendary sword that has passed through centuries of history. The burnt finish is not merely aesthetic — it also provides a degree of surface protection against moisture and oxidation. Each blade has a unique burnt pattern — no two are identical.
