Features: Nobukuni was a prestigious Kyoto swordsmith prospering from the Nanbokucho to the early Muromachi periods. Early works often attributed to Kanemitsu, Nobukuni, and Sadatsugu. This piece shows well-defined choji midare with small gunome midare and is enveloped in irregularities. The refined Kyoto Nobukuni jigane features soft choji midare intermingled with fine kinsuji, creating a beautiful pattern. The bo-hi on both sides adds a unique elegance to this sophisticated piece.

Aoi Art’s Comment: A sophisticated Kyoto Nobukuni Tachi. Nobukuni thrived from the Nanbokucho to the Eiyo periods, but this work is an excellent example of the Nanbokucho period with a good shape. The Tachi Koshirae included is also of decent quality.
