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.

Thin iron tsuba of round form pierced with six three-leaf wood sorrels (katabami) in ko-sukashi and inlaid with brass decoration along the rim. Kozuka-hitsu-ana probably cut at a later date.

Late Muromachi or Momoyama period, 16th century. Dimensions: 78.0 x 77.7 x 2.5 mm.

Iron tsuba of 14-petal chrysanthemoid form (kikka-gata) with alternating solid and openwork petals, the latter outlined with brass wire (sen-zōgan) and the former decorated with brass dots (ten-zōgan), on both sides. Seppa-dai is outlined with brass wire. Small hitsu-ana probably cut later. Late Muromachi period (Ca. 1514-1573). Ōnin school. Unsigned. Dimensions: 87.0 x 87.8 x 3.2 mm.

Joly and Kumasaku Tomita, Japanese art and handicraft, "Swords and sword fittings" section, sub-section “Inlays of Ōnin, Kyoto, Fushimi-Yoshiro, and Kaga Province”, Plate CX, #128: Iron, chrysanthemoid, thin guard with alternate petals covered with brass spots. Ōnin style. 16th century. Compton Collection, Part I, #7: The iron plate is of flowerhead shape with each of the fourteen petals alternating between solid and openwork. The apertures are outlined in inlaid brass as is the seppa-dai and hitsu-ana. The remainder of the plate is similarly inlaid with plum flowers, birds, dots of dew, Genji mon and sambiki mon. 87 mm x 85 mm x 3.5 mm. And at Jim Gilbert website: Onin ten zogan tsuba, mid Muromachi. Size: 7.7 cm T x 7.6 cm W x 0.3 cm. Iron plate with brass inlay. Kiku gata. The Ōnin ten zogan style is characterized by the decoration of small brass “nail heads” and wires on a thin iron plate.  The iron often has a soft, granular texture and seems to be prone to rust.  Unfortunately, this rust will undermine the brass inlay and result in the loss of some of the inlay.  This example is in reasonably good but far from perfect condition.  As is often the case, the backside is better preserved, with the wire around the seppa-dai and kozuka-ana, and all petals still intact.
