This large tsuba features a robust iron ground with a finely crafted rope-patterned rim. Asymmetrical kakumon (angular crests) are arranged in openwork and sukidashi-bori, elegantly adorned with gold inlay arabesque patterns along their edges. The geometric kakumon and delicate gold inlay curves harmoniously blend, creating a dignified aesthetic. While maintaining the traditional Shoami style, the design reveals a unique originality. It was judged as Akita Shoami and passed Hozon Tosogu certification in February 2026.
