This small, flat piece made of light brown brass (called "sentoku" in Japanese) has a round diamond shape. It has a triangular shaped hole in the center and another round hole on one side. Artist’s name is signed between the two holes. The surface is slightly concaved from the rim. The front has relief design of a shrimp, blowfish, and bamboo branch. On the back, there are designs of a spiral shell, a barnacle, and water drops. The sea motifs are inlayed with gold, silver, copper, and shakudô (copper-gold alloy).
Tsuba (sword guard) is inserted between a sword handle and blade to protect hands from sharp blades. The center hole is where the sword is placed. The smaller hole is to insert an ornamental stick called kozuka. This particlar tsuba has a sea-related theme of shrimp and blowfish.

Circular tsuba, made of iron. It has two holes in the middle. Two figures, Kanzan and Jittoku, are carved on the lower right corner. Kanzan, who holds a scroll on his hand, and Jittoku, who holds a bloom stick and pointing to the sky, are looking upward. The two figures are carved slightly higher than the surface. On the back, there is the moon partially obscured by clouds. Gold and silver alloy inlays are applied to the moon and the clouds. Gold is also inlayed in their eyes, parts of the garments, and Kanzan's scroll. Shakudô (copper-gold alloy) is inlayed in Jittoku's bloom and his jacket collars.
Kanzan and Jittoku are Taoist eccentrics of whom little is known, but they are frequently represented (almost always together) in East Asian arts. Both lived in the monastery of Kuo Ching, spending most of their time in the kitchen, and speaking a gibberish unintelligible to anyone, resenting visitors, and noticing them only with insults. Kanzan holds a scroll, which he expounds to Jittoku, who stands by leaning on his broom. Both have a dwarfed and somewhat boyish appearance, but Kanzan's face is furrowed by age.

This small, flat metal piece has a circular shape and an openwork design. It has a triangular shaped sword hole in the center, flanked by two other holes, which are filled with shakudô (copper-gold alloy). The sword hole is mended with gold. Three crests, consisting of pawlownia leaves and flowers, are interconnected with vines. There are some abrasions on the center oval shape around the sword hole. The surface is slightly textured by minute stippling. The outer rim is slightly elevated from the inner design. This openwork carving technique is called "marubori" (round carving).
Tsuba (sword guard) is inserted between a sword handle and blade to protect hands from sharp blades. The center hole is where the sword is placed. The smaller holes are to insert kozuka (left), an ornamental stick, and kougai (right), a spatula-like stick which is said to be used for itching hair underneath hats or helmets. This particlar tsuba has three crests of "Gosangiri" (pawlownia with three-five-three flower petals), which perhaps was the family crest of the owner of the original sword.
