• Iron tsuba of quatrefoil form with design of bamboo stems and leaves, and a plank bridge in openwork (sukashi). Hitsu-ana of irregular form. Iron with smooth chocolate patina. Copper and shakudō sekigane. This piece is illustrated in Sasano: Japanese Sword Guard Masterpieces from the Sasano Collection, 1994 on page 295 under № 254 with the following description:
    Nishigaki. First generation Kanshiro (died in the sixth year of Genroku, 1693, at the age of 81). Sukashi design: Bamboo (take). Early Edo period, late 17th century (Kanbun / Enppo era). Height: 72.6 mm; Width: 71.5 mm; Rim thickness: .6 mm; Centre thickness: 5.1 mm. Rounded rim. The shape of this sword guard is a quatrefoil and the design is arranged in the form of a saddle flap. Two bamboo trunks with leaves comprise the design. Calm, soothing and sophisticated are the features of this artist in his later years. Such characteristics may remind one of the work of the first Hikozo.
    Provenance: Sasano Masayuki collection, № 254. What is interesting, and what had been found by Bruce Kirkpatrick, is that in the earlier photograph of the same piece ['Sukashi tsuba - bushido no bi' by Sasano Masayuki, photography by Fujimoto Shihara, 1972 (in Japanese), page 245, №201] we clearly see kebori - linear carving that decorates the bamboo leaves and the planks of the bridge. The said kebori have totally disappeared between 1972 and 1994. The tsuba became absolutely flat! Now we can only speculate about the reasons for such cruel treatment of the artistically and historically important item.

  • Iron tsuba of oval form with design of  a gourd or aubergine vine with fruits, leaves, and blossoms climbing a trellis, and a fence in yellow brass and red copper flat inlay (hira-zōgan); inlay engraved. Two latticed windows represented by openwork (sukashi). The iron web has deep black patina. The seller attributes this tsuba to Heianjo-Namban school, whatever it means. Momoyama or early Edo period, 17th century. Kaga or Heianjō School. Unsigned. Height: 77.3, Width: 73.1, Thickness at seppa-dai: 3.6 mm.
  • Iron tsuba of round form with design of two paper lanterns in openwork (small cut-outs, ko-sukashi ) outlined with brass wire. The plate is decorated with four concentric rows of brass dot inlay (ten-zōgan), with a brass circular wire inside the innermost row of dots (missing on the back). Hitsu-ana of rectangular form is not outlined with brass wire, which let us suppose that it was cut out at a later date. Copper sekigane. Mid Muromachi period (1454-1513). Diameter: 74.0 mm, thickness: 2.6 mm. Tsuba is illustrated at: 新版 日本刀講座 小道具鑑定編 本間 薫山 佐藤 寒山 : Shinhan Nihonto Koza, Volume VI, Kodogu Part 1. Under supervision of Honma Kunzan and Sato Kanzan. 鍔 無名 応仁 鉄地) 丸形 小透 槌目 真鍮据文 点象嵌 丸耳 : Tsuba with no signature, Ōnin style. Base metal iron (jigane), round shape, small perforations (ko-sukashi), hammering finish (tsuchime). Pre-cast brass inlay (shinchu suemon-zōgan); dot inlay (ten-zōgan); round edge (maru-mimi). English translation of the book indicated above Nihon Tō Kōza, Volume VI, Part 1 by Harry Afu Watson, AFU Research Enterprises, Inc., 1993. Tsuba in question illustrated on page 14 and described as follows: " Tsuba mumei Ōnin. Tetsu ji maru gata ko-sukashi tsuchime shitate shinchū suemon ten zogan maru mimi. Brass suemon". My question remains: why such a text is called 'translation' while it looks more like transliteration of romanization?
  • Iron tsuba of round form with design of two parallel crossbars and two rings in openwork (sukashi). Rounded square rim. Moderate iron bones (tekkotsu) allover. Copper sekigane. Kanayama school. Momoyama period (or late Muromachi). Size: 74.5 x 74.0 x 5.5 mm. The rings possibly represent the sun and the moon, or the stars. The parallel crossbars may represent the "two stripes" (futatsu biki) family crest (incl. Ashikaga family).
  • Iron tsuba of round form with design of military commander's fan (gunbai) in openwork (sukashi). Square rim. Hitsu-ana plugged with lead or tin. Ko-tosho school. Mid-Muromachi period (1454-1513), Entoku era (1489-92) / Meio era (1489-1501). Height: 80.3 mm, Width: 81.5 mm, Rim thickness: 3.0 mm. Centre thickness: 3.5 mm. Provenance: Sasano Masayuki Collection,  №23 in Japanese Sword Guard Masterpieces from the Sasano Collection, 1994: Ko-tosho. Sukashi design: Military commander's fan (gunbai). Mid Muromachi period. Late 15th century (Entoku / Meio era). The military commander's fan (gunbai) was cherished by samurai warriors. This tsuba is relatively thick, with the large fan nicely positioned on the plate.
  • Iron tsuba of round form decorated with two boar's eyes (inome) and two dragonflies (tombo) in small openwork (ko-sukashi) outlined with brass wire. The plate also decorated with 2 to 5 concentric circular rows of brass dots (nail heads) in ten-zōgan. Center of the plate outlined with the inlaid circular brass wire. The inlaid metal is of red-ish hue, so it may be copper, and not brass. The surface has remnants of lacquer. Ōnin school. Mid Muromachi period, middle of 15th century. Dimensions: Diameter: 90 mm, thickness: 3.2 mm. Notes regarding design: "According to various sources, the dragonfly (tombo) is emblematic of martial success, as various names for the insect are homophones for words meaning "victory". The dragonfly is also auspicious because references in the Kojiki and Nihongi link it in both name and shape to the old kingdom of Yamato."  [Merrily Baird. Symbols of Japan. Thematic motifs in art and design. Rizzoli international publications, Inc., 2001, p. 108]. "The dragonfly (tonbo), was also called kachimushi in earlier times, and due to the auspicious literal meaning "victory bug" of the characters of this word it became a popular theme on sword fittings." [Iron tsuba. The works of the exhibition "Kurogane no hana", The Japanese Sword Museum, 2014, p. 13]. Two other cutouts - in the form of what in European tradition symbolizes the heart, on the top and in the bottom of tsuba disc - may have two different explanations. The most usual one, inome - "Heart-shaped pattern, which is said to go back to the shape of a wild boar's eye" [Markus Sesko. Encyclopedia of Japanese Swords. Print and publishing: Lulu Enterprises, Inc., 2014.]. This understanding is shared by Robert Haynes [Robert E. Haynes. Study Collection of Japanese  Sword Fittings. Nihon Art Publishers, 2010.] and elsewhere, with an exception of Okabe-Kakuya [Okabe-Kakuya. JAPANESE SWORD GUARDS. Museum of Fine Arts, Boston. In cooperation with the department of Chinese and Japanese art; - 1908, p. 14], who provides the illustration of inome-shaped cut-outs with the following explanation: " The tsuba shown in Fig. 13 approaches a square form with rounded corners and is perforated with Aoi decoration. But this book was written long time ago, when people even at MFA might not know enough... The same interpretation of the said heart-like symbol (aoi leaf) is given at Helen C. Gunsaulus. Japanese sword-mounts in the collection of Field Museum. // Publication 216, Anthropological Series, Volume XVI; Chicago, 1923; p. 54: "This mokkō-formed tsuba recalls the aoi form, perforated as it is with the four aoi leaves." It is possible that the "wild boar's eye" theory was developed by later scholars.   There is also a theory, supported by Graham Gemmell, saying that: “In simple terms Onin works are decorated Ko-Katchushi tsuba. … But, not content with iron alone, they began to decorate it with what was, in the early Muromachi period, a rare and valuable metal, brass. The Onin workers cut the design into the iron, using narrow channels, cast the brass, piece by piece, and then hammered it into the iron plate as though they were putting together a jigsaw. When complete the tsuba would be black lacquered exactly as the plain iron ones had been, the brass shining dully through it in a way that fulfilled the goal of shibui or restrained elegance.” [Tosogu. Treasure of the samurai. Fine Japanese Sword Fittings from The Muromachi to The Meiji Period, by Graham Gemmell. // Sarzi-Amadè Limited, London, 1991. An exhibition held in London from 21st March to 4th April, 1991]. The following illustration from Helen C. Gunsaulus. Japanese sword-mounts in the collection of Field Museum. // Publication 216, Anthropological Series, Volume XVI; Chicago, 1923; pp. 43 supports the idea. Helen C. Gunsaulus' description of the dragonfly emblem is as follows: "This motive, the dragon-fly  (akitsu), is generally accepted as a symbol of the kingdom of Japan, and the origin of the idea is traced to the legend recounted in the Kojiki and Nihongo of the Emperor Jimmu's view of the island from mountain top. He is said to have thought the kingdom looked like a dragon-fly touching its tail with its mouth. From this it received its name Akitsu-shima... etc."  
  • Iron tsuba of round form decorated with floral motif in brass or copper inlay (suemon-zōgan) and family crests (mon) in small openwork (ko-sukashi). Occasional brass dots or nail heads in brass ten-zōgan. Sukashi elements outlined with inlaid brass wire. Seppa-dai outlined with rope-shaped brass wire (nawame-zōgan); kozuka-hitsu-ana outlined with scalloped brass wire. Ōnin school. Mid to late Muromachi period, 15th or 16th century. Height: 88.9 mm; Width: 88.5 mm; Thickness at seppa-dai: 2.9 mm. Family crests (mon) in openwork: cherry blossom (sakura) - kamon of Sakurai and Yoshino clans, four-section lozenge (waribishi) - kamon of Takeda clan, the seven stars of the big dipper (maru ni nanatsuboshi) - kamon of Chiba clan, two encircled stripes (futatsubiki) - kamon of Ashikaga clan. Brass inlays represent flowers, branches and leaves, as well as halved plum blossom, halved chrysanthemum blossom, cloud, and chrysanthemum-on-water symbol - the mon of Kusunoki Masashige. Abundance of family crests of so many powerful warrior clans symbolizes heritage. "The brass trim around the kozuka hitsu-ana andd the seppa-dai are characteristics of Onin work" [Japanese sword guards. Onin - Heianjo - Yoshiro. Gary D. Murtha. GDM Publications, 2016; p. 27.]
  • Iron tsuba of round form with a butterfly (left) and dragonfly (right) design in openwork (sukashi), outlined with brass wire. The thin plate is also decorated with five concentric circular rows of brass dots (nail heads) in ten-zōgan; brass wire outlines the centre of the plate. School: Ōnin ten-zogan. Late Muromachi period, 16th century. Diameter: 88 mm, thickness at seppa-dai: 3.1 mm. Another tsuba of similar design, Tōshō school, is illustrated in this collection; see TSU-0353.2018. The design is referenced in LIB-1359.2017 Japanese Swords and Tsuba from the Professor A. Z. Freeman and the Phyllis Sharpe Memorial collections, Sotheby's, London, Thursday, 10 April 1997; p. 18, item 37: "pierced with two large formalised butterflies..."

    A Kamakura-bori tsuba of octagonal form, Momoyama period

  • Iron tsuba of round form with design of hatchet executed in openwork (sukashi) and three fan panels motif on both sides carved in low relief (sukidashi-bori). Designs on the fan panels - face: bellflower, plum blossom in mist, grass leaves; - back: clouds, grass, and half plum blossom in mist. Copper sekigane. Koga-hitsu-ana probably cut out on a later date. Kamakura or kamakura-bori school. Edo period. Height: 83.8 mm, Width: 82.2 mm, Thickness at seppa-dai: 3.2 mm. NBTHK certificate № 4005500: Hozon (worthy of preservation).
  • Onin Tsuba with two overlapping lozenges, or interlocked diamond shapes. Iron and brass. Sukashi and ten-zogan technique. Muromachi period. Diameter: 81.0 mm; Thickness at seppa-dai: 3.2 mm The symbol of two overlapping lozenges (or, interlocked diamond shapes), presumably a family crest (kamon) may be deciphered as chigai kuginuki (nail extraction tool => 'conquered nine castles' ) or as chigai bishi (overlapping lozenges). Similar symbol can be found at Butterfield & Butterfield. IMPORTANT JAPANESE SWORDS, SWORD FITTINGS AND ARMOR. Auction Monday, November 19th, 1979. Sale # 3063], №94 with the following explanation: " This was the mon (crest) of the Yonekura family of Kaga Prov., at Kanazawa". An interesting insight is provided by Robert E. Haynes at Important Japanese kodogu, gaiso and works of art. San Francisco, April 9-11, 1982. Robert E. Haynes, Ltd., № 36 (see photo): "This would seem to be the Yonekura family mon. They were Seiwa-Genji Daimyō family made noble in 1696 and resided in Kanazawa in Kaga". Would it be possible that this is a late 17th century Ōnin tsuba?

  • Iron tsuba of slightly elongated round form decorated with three pairs of snowflake-form small perforations (ko-sukashi), each outlined with brass wire; five concentric circular rows of dots inlaid in brass or copper ten-zōgan (some dots are missing). Hitsu-ana of oval form. Ōnin school. Unsigned. Late Muromachi period. Dimensions: 75.6 mm x74.6 mm x 3.0 mm. Weight: 78.0 g. Old NBTHK certificate (green paper): Tokubetsu Kicho - "Extraordinary Work". Unlike most Ōnin ten-zōgan tsuba this one does not have circular brass wire inlay inside the dots area; neither it has brass trim around seppa-dai or hitsu-ana.  
  • Iron tsuba of round form pierced with design of paulownia (kiri) in a circle in positive silhouette (ji-sukashi), details carved in low relief (sukidashi-bori). Hitsu-ana were cut later and then both plugged with lead or pewter. Brown patina. The most unusual characteristic of this tsuba is its 'positiveness': the absolute majority of Kamakura-bori tsuba are of ko-sukashi type, i.e. with small openings, presenting the motif in negative silhouette. Kamakura-bori school. Muromachi period (ca. 1450). Size: Height: 85.1 mm, width: 84.8 mm, thickness at seppa-dai: 3.2 mm, at rim: 2.8 mm. Weight: 79.1 g. A similar tsuba is presented at Japanese Swords and Sword Fittings from the Collection of Dr. Walter Ames Compton. Part I. Christie's, New York, March 31, 1992, page 11, №3: "A Kamakura-bori tsuba. Muromachi period, ca. 1450. The round iron plate is pierced with an openwork design of a paulownia crest (kiri-mon), the surface details of which are carved in low relief. The design is repeated on the reverse. The edge is slightly raised  and the rim has some iron bones. 78 mm x 77 mm x 3.5 mm. Hakogaki by Sato Kanzan, dated summer 1973."

    Compton's Collection, Part I, p. 11, №3.

  • Iron tsuba of round form with design of lattice (kōshi-mon, 格子文) cut in openwork (sukashi), with low relief shallow linear carving along the bars. Well forged plate with brown-ish hue. To the right of nakago-ana there is a clear inscription of the character Shō (正), which is explained by Markus Sesko is follows: "The Shinsa obviously recognized more from the signature when having the tsuba in hand, i.e. they were confident to say it is signed "Shōami" but the rest is illegible (ika-fumei, 以下不明). That is, if they were just able to read the first character SHŌ (正) and saw that there were two more, most likely A (阿) and MI (弥), they would have put those character in boxes on the paper. Boxes around characters namely means that the character is not 100% legible but it can be assumed what it is." Momoyama or early Edo period. Dimensions: 85.9 mm diameter, 3.6 mm thickness at seppa-dai. Weight: 79 g. NBTHK certificate № 425069 with attestation: Hozon - "Worthy of preservation". A similar tsuba is presented at Japanese Sword Fittings from the R. B. Caldwell Collection. Sale LN4188 "HIGO". Sotheby's, 30th March 1994, №15. The description says: "A rare early Kamakura-bori tsuba. Nambokucho period (late 14th century). Of circular form, the dark plate carved and pierced with a gate design, the struts with double engraved lines. Unsigned. 8.5 cm." The lot was sold for 1,840 GBP.

    Caldwell Collection. Sotheby's 1994, №15.

    We have two possible explanations of the discrepancy between Sotheby's and Shinsa/Sesko attribution: 1) either Sotheby's or Shinsa/Sesko were wrong in their attribution or 2) these are two different pieces, one - Kamakura-bori from the 14th century and another - Shōami from 16th/17th century. Anyway, I would consider my piece as a Shōami tsuba of Momoyama - early Edo period, just for the sake of modesty.    
  • An iron tsuba of slightly vertically elongated circular form carved and pierced with a mass of ivy (tsuta) leaves and tendrils, details damascened with gold in nunome-zōgan technique. Hitsu-ana with raised rim.

    Unsigned.

    Chōshū school.

    Height: 72.0 mm; width: 69.0 mm; thickness: 4.7 mm; Weight: 92 g.

    According to John W. Dower, "ivy bears fairly close resemblance to both maple leaf and grape leaf". However, I consider this tsuba decorated with ivy leaves for several reasons, such as the lack of racemations in the presence of tendrils.
  • Kyo school iron tsuba of round form decorated with an eight-plank bridge (yatsuhashi) and irises (kakitsubata) in openwork (sukashi).

    Late Muromachi period, Tenbun era (early 16th centiry).

    Dimensions: 80.0 x 77.2 x 4.1 mm.

    The design alludes to the scene in 'Ise Monogatari', where Ariwara no Narihira being exiled from Kyoto to the Kanto region crossed the eight-plank bridge at Mikawa looking at the irises in bloom and composed a poem expressing his desire to return to Kyoto. A lot of tsuba have been produced with the similar design.

Gilloz, number 1302. [SV: that's possibly the 'old French collection' of Robert Haynes.]

    Caldwell Collection, #13.

    If we accept Haynes' theory regarding the genealogy and history of Bizen Shōami family, Momoyama period attribution would seem unlikely. I am leaning towards the early to mid 17th century.
  • This tsuba is a cut from a typical Bizen Shōami butterfly tsuba (see TSU-0100 in this collection), which normally would have had a circular rim around the butterfly. In this particular example of altered guard we have both eyes of the insect (inlaid in brass or copper) intact. The kebori carving is more pronounced than in TSU-0100 example. Copper sekigane. Unsigned. Attributed to Bizen Shōami school, early Edo period (17th century). Dimensions: 64.7 x 63.7 x 5.2 mm References: see TSU-0100.
     
  • Iron tsuba of circular form with a branch of loquat (biwa) pierced in positive silhouette (ji-sukashi) and carved in marubori technique (marubori-sukashi). Kozuka and kogai hitsu-ana are plugged with shakudo.

    Signature: Choshu Kawaji ju Hisatsugu saku. Chōshū school in Nagato province.

    According to M. Sesko 'Genealogies' Hisatsugu was a 4th generation Kawaji School master from Chōshū (present day Nagato), with the name Gonbei, formerly Toramatsu, adopted son of Tomohisa (1687-1743) [page 117]. For Tomohisa work see TSU-0104 in this collection.
  • Iron tsuba of mokko form with rough surface decorated in low relief carving (sukidashi-bori) and openwork (sukashi) with a flying bat, a crescent moon, and a cloud over the moon. Bat's eyes inlaid with gold. Crescent moon and cloud on the reverse. Copper sekigane. Kogai hitsu-ana plugged with shakudō.

    Unsigned.

    Edo period.

    Size: Height: 83.7 mm; Width: 80.3 mm; Thickness: 2.9 mm; Weight: 141 g.

  • Iron tsuba of circular form with the knotted geese (kari) flying over the rough waves pierced (sukashi) and carved in low relief (nikubori). Hitsu-ana plugged with soft metal. Hitsu-ana plugged with soft metal (tin or lead).

    Signed: Echizen koku jū Myochin Katsuharu saku.

    Edo period.

    Size: Height: 80.7 mm; Width: 81.0 mm; Thickness: 4.5 mm; Weight: 110 g.

    Two tsuba of this master can be found at Georg Oeder Collection (Japanische Stichblätter und Schwertzieraten. Sammlung Georg Oeder Düsseldorf. Beschreibendes Verzeichnis von P. Vautier.

  • Iron tsuba of round form with a Marsilea (water clover, paddy plant, denjiso) in openwork (sukashi) and a cricket carved in low relief (katakiribori) with extremities and one antenna inlaid with brass; the other antenna is carved in kebori (which antenna is inlaid and which is carved alternates on the face and on the reverse). The plate decorated with vertical file stroke ornamentation (tate-yasurime). Raised dam-shaped rim (dote-mimi). Inscription from a previous collector in red oil paint: 22-71-1. Edo period, possibly 17th century. Katchushi school.

    Size: 75.0 x 74.4 x 3.6 (center), 5.0 (rim) mm.

    The plant Marsilea (paddy plant, denjiso), common names include water clover and four-leaf clover because the long-stalked leaves have four clover-like lobes and are either held above water or submerged. In The elements of Japanese design by John W. Dower, this motif is listed under the numbers 634-35 Paddy Plant (denjiso). Obviously, as a four-leaf clover it is an auspicious symbol. The four leaves radiate out as the shape of the kanji (romaji 'ta'), which means 'rice paddy'. This symbol may be used as a family crest (mon), and this would be the most probable explanation of the sukashi on this tsuba.  
  • Iron tsuba of round form pierced (sukashi) and carved (marubori) with a 'noshi' decoration design. Noshi - decoration made of dried abalone (awabi) and bearing an auspicious connotation of good fortune, prosperity, etc. Design was used as a family crest (mon).

    Size: 76.3 x 75.9 x 5.5 mm.

    Signed: Echizen jū Kinai Saku. Kinai school existed from mid 17th to mid 19th century; it is hard to tell which master (generation from 1 to 6) made this particular piece.

    SOLD

    "A Tosa Myochin School Tsuba. Edo period (circa 1750), signed Toshu ju Kuniyoshi saku. The round iron plate pierced with a design of a temple gate (torii) and a pine tree. It has a round rim and there are some carved details on the surface of the design. The Tosa Myochin school, despite its foundation in the classic Myochin armor school tradition, worked mainly in the style of Akasaka school of Edo. [...] Many are equal to the mid to later Akasaka school work and the two types have frequently been confused. Signed examples are rare. Estimated price $1,500-2,000."

    Unsigned.

    Edo period, ca. 17th century.

    NBTHK Certificate № 463485. The certificate says it's a Higo School piece. The design was popular in both Akasaka and Higo schools. The Akasaka example: at Kodogu and tsuba.

    Muromachi period, ca. 16th century.

  • Iron tsuba of octafoil form with design of rudder (kaji) and lake in openwork (sukashi) outlined with brass wire. Thin plate also decorated with three concentric circular rows of brass dots (nail heads) in ten-zōgan. Center of the plate outlined with the inlaid circular brass wire. Cut-outs for kozuka and kogai probably added later.  Slightly raised rim between the indentations (suki-nokoshi-mimi). The inlaid metal of red-ish hue, so it may be copper, not brass. Sekigane, visible on the NBTHK paper photo, are missing, possibly removed by a previous owner. Muromachi period. Ōnin school. Unsigned. Dimensions: 81.2 mm x 81.8 mm x 2.7 mm. Weight: 79.0 g. Large nakago-ana: 34 mm high and 10 mm wide. NBTHK certificate №455786: Hozon. Note regarding design: it was quite hard to interpret the big oval opening. The first suggestion was 'sea cucubmer', and it was based on a design published by Kazutaro Torigoye [Kodogu and tsuba. International collections not published in my books (Toso Soran), 1978] on page 202: Katchūshi tsuba: Sea cucumber and butterfly. Look and judge yourself:

    Torigoye: sea cucumber and butterfly.

    The second suggestion - 'lake' - came from [Iron tsuba. The works of the exhibition "Kurogane no hana", The Japanese Sword Museum, 2014], page 14 №5:

    Ko-Katchūshi tsuba: Lake and pine.

    Opening on my tsuba looks more like the 'lake'. Also, rudder and lake make more sense than rudder and sea cucumber. At least to me...    
  • Iron tsuba of oval form decorated with design of jakago (bamboo lattice work) in openwork (sukashi). Copper sekigane.

    Unsigned. Edo period.

    Size: 73.7 x 70.3 x 5.6 mm.

    Note regarding design: though some might think that this piece belonged to a member of the lost tribe of Israel, it did not. Jakago baskets were made of bamboo, filled with rocks and used to catch crabs (besides other uses).

  • Iron tsuba of oval form pierced with design of slanting rays of light (shakoh), a Christian motif (Jesuit’s IHS symbol), and a pair of tassels in positive silhouette (ji-sukashi). Details on tassels carved in low relief. Traditional description of this kind of design is called “tokei”, or “clock gear”. Rounded rim.

    Unsigned.

    Edo period, 17th or 18th century. Possibly - Owari school.

    Size: 76.0 x 73.0 x 6.2 mm.
  • Iron tsuba of round form decorated with design of sea waves in low relief carving (kebori) and pierced with design of cherry blossom in negative silhouette (in-sukashi) and water wheel in positive silhouette (ji-sukashi). The solid portion of the plate has a shallow groove just before the edge. Copper sekigane. School attribution is unclear. Unsigned. Momoyama period, 16th - 17th century. Dimensions: Height: 70.3 mm, width: 71.1 mm, thickness at seppa-dai: 4.4 mm, at rim 4.1 mm. Provenance: Robert E. Haynes, Mark Weisman. This is what shibuiswords.com says about this tsuba:
    "A very unusual iron plate tsuba. The solid plate is carved with waves on both sides. A cherry bloom in sukashi, lower left, and the right third of the plate in openwork with design of a water wheel. The rim with some iron bones. The hitsu-ana is original but the shape may have been slightly changed. One would expect this to be the work of the early Edo period, but the age of the walls of the sukashi would suggest that this is a work of the middle Muromachi period. This must be the forerunner for the Edo examples we see of this type of design." (Haynes)
    I managed to find a look-a-like tsuba in Haynes Catalog #5, 1983, pp. 20-21, №44: "Typical later Heianjo brass inlay example. Ca. 1725. Ht. 7 cm., Th. 4.5 mm., $100/200".

    Haynes Catalog #5, 1983, pp. 20-21, №44.

    We see that the  plate design of both tsuba is the same, and the only difference is the trim. It would be logical to assume that both pieces were made at about the same time, rather than 225 years apart. To be fair, let's accept that they were made in Momoyama period.
  • 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.

    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.
  • Iron tsuba of round form decorated with dragonfly (tombo) and comma (comma-like swirl, tomoe) in openwork (sukashi) outlined with brass wire. The plate decorated with 5 concentric circular rows of brass dots in ten-zōgan. Center of the plate outlined with the inlaid circular brass wire (sen-zōgan). Ōnin school. Unsigned. Mid Muromachi period, middle of the 15th century. Dimensions: Diameter: 89.5 mm, thickness: 3.1 mm. Notes regarding design: "According to various sources, the dragonfly (tombo) is emblematic of martial success, as various names for the insect are homophones for words meaning "victory". The dragonfly is also auspicious because references in the Kojiki and Nihongi link it in both name and shape to the old kingdom of Yamato."  [Merrily Baird. Symbols of Japan. Thematic motifs in art and design. Rizzoli international publications, Inc., 2001, p. 108]. "The dragonfly (tonbo), was also called kachimushi in earlier times, and due to the auspicious literal meaning "victory bug" of the characters of this word it became a popular theme on sword fittings." [Iron tsuba. The works of the exhibition "Kurogane no hana", The Japanese Sword Museum, 2014, p. 13].   Helen C. Gunsaulus' description of the dragonfly emblem is as follows: "This motive, the dragon-fly  (akitsu), is generally accepted as a symbol of the kingdom of Japan, and the origin of the idea is traced to the legend recounted in the Kojiki and Nihongo of the Emperor Jimmu's view of the island from mountain top. He is said to have thought the kingdom looked like a dragon-fly touching its tail with its mouth. From this it received its name Akitsu-shima... etc."
