[ Highlight ] This is a well-made short sword with a gorgeous blade pattern of gunome-midare with koshibiraki hamon patterns, which appears to have been modelled on the Bizen swords of the late Muromachi period. This work is thought to have been made in the late Edo period by a swordsmith of the Koyama Munetsugu lineage, who was a representative of the Edo shin shinto swordsmiths and was renowned as a master of the Bizen style.

[ Conditions ] Excellent.
