Size: 73.2 x 72.4 x 3.6 mm References: 1) Tsuba Kanshoki. Kazutaro Torogoye, 1975, p. 95, lower image. It's also called Kyō shōami. 2) KTK-11: Koshi motif, Late Muromachi (16th c.)

Iron tsuba of round form decorated with design of moon, stars, cloud, snowflake, gorintō, and Genji-mon in negative openwork (in-sukashi). Raised tubular rim (dote-mimi). Deep black patina, traces of lacquer. Naka-daka type of plate (thicker in center, getting thiner towards the rim). Visible gap between the rim and the plate. Dimensions: Height: 91.7 mm; Width: 90.8 mm; Thickness at seppa-dai: 2.5 mm, plate before rim: 2.2 mm, of the rim: 5.6 mm. At least Mid Muromachi period, 15th century, but possibly earlier. In 'Silver Book', commenting tsuba №34 Sasano writes: "The technique used to create the rim is the same used for the peak (koshimaki) of helmets (kabuto) during the Kamakura and Nanbokucho periods." On the other hand, the abundance of sukashi elements points towards later times, perhaps late Muromachi or even Momoyama period. "Gorintō is a grave stone composed of five pieces, piled on one the other, representing, from the bottom upward, earth, water, fire, wind, and heaven, respectively" [Nihon Tō Kōza, Volume VI, Part 1.  AFU, 1993, p. 6. / LIB-1554]. A romantic description of the piece may look like this: The air is scented (incense symbol); it's a graveyard, marked by gorintō; a winter (snowflake) evening or night (moon, stars); mist is rising from a ravine towards moon. I did not manage to find a katchūshi piece of this design, only a few Kamakura-bori tsuba:   While the upper tsuba is dated the end of Muromachi, the lower is attributed to the 17th century - Momoyama or early Edo period, though the author put this attribution under question. Deciphering of the strangely shaped opening to the left of nakago-ana is sometimes "a conventional scroll", and sometimes - a fern or bracken. I think mine is a cloud or mist, but I don't have any material evidence to prove this understanding, and I came to a conclusion based only on context. It may easily be dinosaurs playing ball. The fact that this thing always accompanies the Genji-mon, or incense symbol, it may be a scent itself.

Mokkō-form (kirikomi-mokkō-gata) iron plate of grey colour decorated on both sides with waves, reeds, cloud, pagoda, and thatched hut in low relief (sukidashi-bori). The kozuka-hitsu-ana is original, the kogai-hitsu-ana probably cut later (lacks raised rim, fuchidoru). Wide (5.7 mm) raised rim of rounded square dote-mimi type, decorated with fine cross-hatching. Momoyama period, 16th century. Dimensions: Height: 75.9 mm, width: 76.4 mm, Thickness at seppa-dai: 2.3 mm, at rim 4.4 mm. Kamakura-bori tsuba of such a form is unusual. The rim is also unusual; it is possible that cross-hatching was done as a preparatory step for damascening, or the the damascening (gold or silver) disappeared with passage of time.
