Tsuba, early 18th century (CH 18341971), This iron tsuba is kaku mokkō (square with lobed corners) in shape and has a kaku mimi (square outer rim). Marubori-Sukashi  (round openwork carving) shows a design with a military baton decorated with kin hira zogan (flat gold inlay)  

At the center is the nakago-ana, an opening through which the sword passes. Surrounding this is the seppadai, a flat oval area that is migaki (burnished). The outer rim is round, or maru-mimi. On either side are ryō-hitsu, openings for the kozuka (utility knife) and the kogai (skewer tool). At right is sashi ura, the side which faces the blade, whose opening takes the hangetsu-kei (half moon) shape. Opposite is sashi omote, the side which faces the sword hilt. Its tri-lobed opening is of the suhama type, and symbolically represents the coastline of Horai, the holy island of the Immortals.
