The Gassan school of Dewa Province is one of the most respected traditions in Japanese swordmaking, with a lineage extending from the Koto period into modern times. Authentic Koto-period Gassan Wakizashi are rarely encountered on the market.
Based on its workmanship, excellent Ayasugi hada and overall characteristics, including its ō-kissaki (approx. 6 cm), the blade shows traits associated with the Nanbokuchō to early Muromachi period; however, precise dating remains difficult due to the consistency of Gassan style throughout the Koto era.
Price: $5,600 USD
A solid, papered, and increasingly hard-to-find Ko-Gassan piece for serious collectors.
