• A yamagane  (unrefined copper) ko-kinko tsuba of slightly elongated round form with design of wisteria carved in sculptural relief (nikubori). Copper sekigane. Unsigned. Muromachi period, likely the 16th century.

    Size: 74.3 x 71.8 x 3.2 mm.

    NBTHK certificate №4003986: Hozon (worthy preservation). In custom wooden box.
  • 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).
  • Iron tsuba of four-lobbed mokkō form (possibly it was circular and then altered to produce the mokkō) with slightly raised rim decorated with three kukurizaru ('tied up monkey' toy) in openwork (sukashi) next to kogai-hitsu-ana; inlaid in red-ish copper (suaka) with the design of bamboo stems and leaves, and shapeless masses which most probably represent snow. Kozuka-hitsu-ana plugged with shakudo. Probably original kogai-hitsu-ana. Copper sekigane. Surface still covered with lacquer (urushi). Late Muromachi period (1514-1573). Size: 86.1 x 85.8 x 2.6 mm NBTHK Certificate №4002543: Hozon - "Worthy of preservation" (Attribution: Mumei Heianjō Zōgan)
  • Large and thin iron tsuba of round form (width > height) decorated with the design of a tiger sheltering in bamboo in suemon-zōgan brass inlay. A fragment of tail inlay is missing. Bamboo leaves on the reverse. According to Merrily Baird [Symbols, p. 166], tiger sheltering in bamboo symbolizes "weak giving shelter to the strong". Momoyama period. Unsigned. Dimensions: 90.8 x 91.2 x 3.4 (center), 3.1 (rim) mm. Custom wooden box. NBTHK Certificate № 4001593.
  • Iron tsuba of round form with brown patina decorated with the design of a Buddhist temple bell (tsurigane) in openwork (sukashi), with details outlined in brass wire (sen-zōgan), the outer ring  decorated with two rows of brass dots (ten-zōgan), and the bell details carved in sukidashi-bori as on kamakura-bori pieces.

    Ōnin school. Unsigned. Late Muromachi period, 16th century. Dimensions: 88.8 x 88.3 x 3.0 mm. As per Merrily Baird, two legends are usually associated with the image of tsurigane, a large, suspended Buddhist bell: one is that of Dojo Temple (Dojo-ji), and the other is of Benkei stealing the tsurigane of Miidera Temple. Interestingly, this type of bell (tsurigane) is not described as a family crest (mon), while suzu and hansho bells are.  
  • Iron tsuba of a spindle shape (tate-itomaki-gata) pierced and inlaid in brass suemon-zōgan with bellflowers, vines and foliage, and a dragonfly in the upper right corner, on both sides. One of the hitsu-ana plugged with grey metal (led or pewter), nakaga-ana fitted with copper sekigane. The shape of the tsuba may be interpreted as  four saddles connected to each other by horse bits. Such a design of sukashi and zōgan is usually attributed to Kaga Yoshirō branch of Heianjo school, active in the second half of the 17th century (c. 1650-1700). Size: 95.9 mm diagonal; 4.1 mm thickness. Tokubetsu Kicho certificate № 332 issued by NBTHK on October 12, 1965.  
  • 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 with circular iron wire fastened to the surface with iron and brass staples (mukade-zōgan); brass ring about 2.5 mm wide along the rim with chisel marks. Design repeats on the reverse. Copper sekigane. Early Edo, 17th century. Size: Height: 83.3 mm; width 83.9 mm; thickness at seppa-dai: 4.5 mm. Weight 173.6 g. Design is thought to resemble a centipede. "Centipede-like inlay (mukade zogan) of alternating iron and brass staples produce an appearance that was particularly favored by Takeda Shingen (1521-1573), one of the most powerful warlords of his time. The centipede is sacred to Bishamon (God of War) and especially propitious for a warrior. Shingen type, 16th century.” [The Peabody Museum collection of Japanese sword guards with selected pieces of sword furniture, by John D. Hamilton. Photographs by Mark Sexton. Salem, MA, 1975.] See also: http://varshavskycollection.com/shingen-tsuba/ SOLD
  • 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...    
  • Small iron tsuba (tantō size) of oval form carved with imitation of six overlapping plates, decorated with paulownia blossoms, leaves, and tendrils in brass and copper hira-zōgan. Copper sekigane. Open kozuka hitsu-ana.

    Early Edo period, 17th century.

    Size: 50.5 x 34.0 x 4.9 mm.

  • Iron tsuba of round form with design of ginger and double diamonds (myoga-ni-nigaibishi) in openwork (sukashi), details carved in kebori technique. Slightly rounded square rim. Copper sekigane. Shoami school. Early Edo period: Late 17th century (Kanbun/Enppo era). Height: 80.1 mm. Width: 79.8 mm. Rim thickness: 5.0 mm. Center thickness: 4.7 mm. Provenance: Sasano Masayuki Collection, № 110.  
  • 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 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 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. Similar tsuba in this collection: TSU-0420.2022 Other similar specimens can be found at: Henri L. 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.

    Japanese art and handicraft, Plate CX, #128.

    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.

    Compton Collection, Part I, #7.

    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 mokko form decorated with trellis, vines, foliage, and gourds inlaid in brass with details carved in low relief.

    NBTHK: Tokubetsu Hozon №2003186.

    Momoyama period (1574 – 1603). Dimensions: H: 85.5 cm, W: 79 mm, Thickness (centre): 4.8 mm. Tsuba of a similar design can be found in this collection [TSU-0373]. In that example, the plate was later pierced with geometrical mon-like openwork to resemble Koike Yoshirō's handguards. More about this type of tsuba here.
  • 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 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).

    Kokusai Tosogu Kai, September 24-25, 2005.

  • Circular form tsuba made by a mirror-maker, i.e. kagamishi. Cast yamagane plate with design of six persimmons on their peduncles surrounded by leaves. Slightly raised rounded square rim. Hitsu-ana is brutally cut later in time. Copper sekigane. Early Muromachi period (1393-1457) or earlier. The inscription on the box reads: "Kamakura or Muromachi Period. Yamagane Tsuba". Dimensions: 81.9 x 81.6 mm; thickness at seppa-dai 2.8 - 3.0 mm, rim 3.4 mm.
