Iron tsuba of circular form with design of pine trees (matsu) and monkey toys (kukurizaru) in openwork (ko-sukashi). Ko-Katchushi school.

Raised rim (mimi) with iron bones (tekkotsu). Size: Diameter: 99.5 mm; Thickness: 2.1 mm at centre; 4.3 mm at the rim.

Early Muromachi period: 15th century (Kakitsu - Bun'an era, 1441 - 1449).

Iron tsuba of round form with design of iris and snowflake in openwork (ko-sukashi or small cut-outs) outlined with brass wire. Three concentric rows of brass dots (ten-zōgan), with a brass circular line inside the innermost row of dots (missing on the back). Hitsu-ana is not outlined with brass wire, which let us suppose that it was cut out at a later date. Iron and brass. Ko-sukashi and ten-zōgan technique. Mid Muromachi period (1454-1513). Height: 74.0 mm, Width: 73.6 mm, Thickness: 3.0 mm.

NBTHK certification of 1968: "Kicho". Condition is relatively poor: rust, missing inlay, scratches.

While representation of the snowflake is rather standard, the meaning of the other cut-out design was initially less clear. Similar symbol was found at (1) "Kokusai Tosogu Kai, International Convention & Exhibition, September 24-25, 2005, The Frazier Historical Arms Museum, Louisville, Kentucky, USA"; on page 21 there is a photograph J-6 of a ko-tosho tsuba with "iris theme openwork"; (2) Japanese Swords and Tsuba from the Professor A. Z. Freeman and the Phyllis Sharpe Memorial collections. Sotheby's, London, Thursday 10 April 1997; page 11, lot 6 - a ko-katchushi tsuba of early Muromachi period fith "simple design of stylized iris". In both sources the symbol is explained as 'iris" (kakitsubata).

Iron tsuba of round form with design of double crossbar and two family crests (hikiryo-ni-kamon) in openwork (sukashi). Squared rim. Copper sekigane. Owari school. Early Edo period: Late 17th century (Kanbun / Enppo era). Height: 80.9 mm. Width: 80.8 mm. Rim thickness: 5.0 mm. Center thickness: 4.6 mm. Provenance: Sasano Masayuki Collection, № 172: "A paulownia and a clover are diagonally opposite two crossbars. This expressive design suggests a Higo origin, but the iron and the finish are certainly of the Owari school. Work of this nature may have been influenced by Hayashi Matashichi (1613-1699)."

Iron tsuba of round form decorated with chrysanthemums, pine cones and needles, pampas grass, vines, cherry blossoms, and wild geese in brass inlay (suemon-zōgan) and pierced with designs of water clover (denjiso) and half bellflower (or karahana) to the left and to the right of nakago-ana as well as double bars above and below nakago-ana (possibly with the meaning of number 2 or ordinal 2nd). Most probably the sukashi elements here are the family crests (mon). Unsigned. Ōnin school. Muromachi period; 15th or 16th century. Height: 82.1 mm; Width: 80.9 mm; Thickness at seppa-dai: 2.4 mm NBTHK # 2003827: Tokubetsu Hozon Tosogu Kanteisho (特別保存刀装具鑑定書) - "Extraordinarily Worthy of Preservation".

The thin, four-lobed iron plate of brownish color is carved on each side with two concentric grooves in the middle of the web, and with four thin scroll lines (handles, kan) that follow the shape of the rim. The hitsu-ana were added at a later date.  Copper sekigane. Kamakura-bori school. Muromachi period, circa 1400-1550. Size: Height 80.4 mm, width 79.0 mm, thickness 3.2 mm at seppa-dai and 2.7 mm at the rim. Weight: 97.7 g. NBTHK Certificate №4004241: 'Hozon' attestation. As for the motif: the concentric circles is a widespread and generic design. It is described by John W. Dower [The Elements of Japanese Design, 1985, p. 132, #2201-30] as follows: Circle: Enclosure (wa). As a crest by itself, the cirlce carries obvious connotations of perfection, harmony, completeness, integrity, even peace. [...] Ordinary circles are labeled according to their thickness, with terminology ranging from hairline to "snake's eye". The motif that is described by both Compton Collection and R.E. Haynes as "scrolls", presented by John W. Dower as "Handle (kan): Although probably a purely ornamental and nonrepresentational design in origin, over the centuries this motif acquired the label kan, denoting its resemblance to the metal handles traditionally used on chests of drawers. [...] Very possibly the "handle" motif represents an early abstract version of the popular mokko, or melon pattern." Early Chinese Taoists claimed that special melon was associated with the Eastern Paradise of Mount Horai just as life-giving peaches were associated with the Western Paradise of the Kunlun Mountains. [...] A design motif called mokko (also translated as "melon" in accordance with the two ideographs with which it is written) may have nothing to do with the fruit. Mokko designs... are widely used as crests of both private families and Shinto shrines and are repeated as background designs that evoke a sense of classicism" [Symbols of Japan. Merrily Baird, 2001]. There is a look alike tsuba at Dr. Walter A. Compton Collection, 1992, Christie’s auction, Part II, pp. 14-15, №16: The description goes: “A kamakurabori type tsuba, Muromachi period, circa 1400.

Haynes Catalog #9 on page 24-25 under №23: R.E. Haynes description: “Typical later Kamakura-bori style work.
