• Tsuba of oval form decorated with vines, tendrils, and leaves on trellis in brass inlay with details carved in kebori, and pierced with six family crests (mon) with two, three and four pointing stars in openwork, each outlined with brass wire and carved in kebori. Original hitsu-ana outlined with brass wire was probably enlarged later. Copper sekigane.

    Momoyama to early Edo period (end of the 16th - beginning of the 17th century). Dimensions: 68.3 x 64.5 x 3.4 mm.
  • Tsuba of oval form decorated with clematis six-petal flowers, tendrils, and leaves in cast brass with details carved in kebori, inlaid on iron plate carved in low relief  (kebori and sukidashi-bori). Hitsu-ana plugged with shakudō. Copper sekigane.

    Heianjō (or Ōnin) school. Unsigned. Mid Muromachi period (1454-1513). Dimensions: 87.2 x 84.3 x 4.3 mm. Tsuba is illustrated and described in Gary D. Murtha's "Onin-Heianjo-Yoshiro" book on pages 38-39. Mid-Muromachi is the age attribution by Gary. “A picture book of Japanese sword guards. Victoria & Albert Museum“, published in 1927 presents us with a somewhat similar tsuba: "Floral ornament. Iron, with brass incrustation". V&A attributes the tsuba to Ōnin style, 16th century.
  • 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.
  • 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.
  • 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.
  • 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...    
  • Ko-kinko ymagane cast tsuba of mokko form (kirikomi-mokkō-gata) with chiseled diaper pattern of double head waves on both sides and a rabbit cast and carved with its eye inlaid in yellow metal (gold or brass) on the face. Fukurin which holds together the sandwiched layers of metal (sanmai) is about 2.4 mm wide. A look-a-like tsub of oval form instead of mokko-gata  is illustrated at Robert E. Haynes's Catalog #3,1982 on page 11, lot 15: "Rare design in style of Sanmai (three layers) / Wasei work. With yamagane core and heavy rim cover. The web plates are carved with double head Goto style waves and the face has a fox. The web plates were riveted at the seppadai.  See Lot 4, page 8. Ca. 1350. Ht. 6.6 cm, th. 3 mm" [underscore mine]. Quality of photo is so poor that I decided not to provide it here. Muromachi (if we follow Robert) or Momoyama period. The Momoyama attribution is mostly based on a fact that "waves and rabbit" motif became most popular in Momoyama times. Size: 68.5 x 59.8 x 4.0 mm. NBTHK Certificate № 423120. This tsuba is listed at Yakiba website with the following passage: "Attributions as well as dating of this type of tsuba has been the subject debate over the years. There are those who believe these type of tsuba to be ko-Mino (early Mino School) tsuba, others believe them to be tachi-kanaguchi tsuba. Still others insist they are simply ko-kinko (early soft metal) tsuba. This tsuba was authenticated and determined to be "Ko-Kinko" by the NBTHK". Oval form tsuba with the same design can be found in this collection - TSU-0323.

    TSU-0323. Ko-kinko yamagane tsuba with waves and rabbit motif.

  • Iron tsuba of round form inlaid with brass and shakudo (suemon-zōgan) with a design of tendrils, leaves, double gourds, and folding fan with two wild geese on the face and the same design only with a fan with two interlocked rings (wachigai) on the back. Design is supplemented with a round family crest (mon) of three fans in openwork (sukashi). Hitsu-ana and the mon are outlined with brass rope. Copper sekigane.

    Some attribute such tsuba as belonging to Heianjō or even Yoshirō School, and date them to Momoyama period. I keep this piece under Ōnin rubric, late Muromachi, but this is just a question of personal preference.

    Some inlay is missing, some repaired; traces of rust. Otherwise - decent condition.

    Late Muromachi period (1514-1573). Size: 77.4 x 77.1 x 3.8 (center), 3.2 (rim) mm
  • Iron tsuba of round form decorated with a design of bracken scrolls and paulownia leaves and blossoms (kiri-mon) in openwork (sukashi). Details carved in kebori. Squared rim with iron bones (tekkotsu). Hitsu-ana plugged with shakudō.

    Size: 83.6 x 82.9 x 5.4 (center), 5.1 (rim) mm.

    Unsigned.

    Muromachi period, ca. 16th century.

  • Iron tsuba of oval form with the motif of horse trappings in openwork (sukashi). Copper sekigane. Iron bones (tekkotsu) on the rim.

    Size: 80.4 x 75.8 x 5.2 mm

    NBTHK Certificate №454567, allegedly saying that it is Akasaka School, Muromachi period. A look-a-like tsuba in Robert. E. Haynes Catalog #7, 1983 on page 57 under №48 is described as follows: "A masterpiece second period Owari sukashi tsuba. The plate is of beautiful color and quality almost like velvet. The design is very hard to discern, it might be the horse trappings, or even a moon. The style and type of Owari tsuba shows the great tradition of the Momoyama period and why it was the renaissance in time, as well as the arts produced, through the long history of all Japanese art. Ca. 1580. Ht. 7.7 cm, Th. (center) 5.5 mm, (edge) 5.25 to 5.75 mm."

    Robert. E. Haynes Catalog #7, 1983, p. 57, №48.

    I believe we can safely attribute this tsuba to Owari School, c. 1580.    
  • Iron tsuba of otafuku-gata form decorated on the face with death and autumn motifs: autumnal grasses and flowers in yellow brass and shakudō, skull, limb bone and sternum inlaid in shakudō. On the reverse the plate is inlaid in red copper with a chrysanthemum and maple leaves floating in stylized water streams. "Plants floating atop water form common motifs, as occurs with chrysanthemums, maple leaves, and cherry blossoms, in particular." [Merrily Baird]. Such plants may be used as a family crest (mon), or may be just a reminder of a floating nature of life.   Momoyama period, late 15th century. Dimensions: 75.3 x 69.9 x 4.3 mm.
  • Iron tsuba of mokko form decorated with brass flat inlay (hira-zōgan) all over on both sits and going over the rounded rim. Black patina, well-forged iron. Hitsu-ana outlined with brass inlay. Former owner's catalogue number in red paint reads 25-17-61. Gary D. Murtha provides detailed account of this type of tsuba in Japanese Sword Guards. Onin-Heianjo-Yoshiro book on pages 118-122. He calls this type of tsuba "Heianjo Mogusa Tsuba": "The term mogusa is commonly used for an inlay design that represents an aquatic weed, similar to a duck weed or sago plant, which is known to quickly invade and overtake bodies of water. [...] Perhaps the visual image has some cross-over meaning for samurai in that, like the plant, a small aggressive samurai force could conquer a larger foe/area." I tried to find any reference to "mogusa" in literature, - to no avail. Neither on the vastness of internet, including Wikipedia... I did find the "duckweed" (one word), but visually it has nothing to do with the pattern on tsuba. "Sago plant" probably stands for 'Sago palm", and there is some very distant reminiscence in the construction of the sago palm leaf and the said design of inlay, but I would not go that far. In the old catalogues, such as Naunton and Hawkshaw collections, this pattern as called "sea weed" and/or "conventional fir". I will stick to these descriptions, tested by the time, and leave the enigmatic "mogusa" alone. Obviously, this type of tsuba has transformed into Yoshirō tsuba, both in Kaga province and Bizen province. Momoyama period (ca. 1660). Dimensions: 74.5 x 73.7 x 4.4 mm.
  • Iron tsuba of round form represents an eight-spoke Wheel-of-the-Law and in the same time (because of the inner shape of cut-outs) - a sixteen-petal imperial chrysanthemum in openwork (sukashi). Decorated on both sides with vines, leaves, and tendrils in suemon-zōgan and sen-zōgan. Spokes and hitsu-ana decorated with rope-like linear brass inlay (nawame-zōgan). A somewhat look-a-like tsuba is referenced in Gary D. Murtha's Japanese Sword Guards. Onin-Heianjo-Yoshiro book on page 61. Mr. Murtha attributes his piece to Heianjo school of Azuchi-Momoyama or early Edo period. However, tsuba in this collection looks older and bolder than the one in his book. It is larger (84 mm vs. his 66 mm), the spokes are longer, the inlay is of better quality, it is relatively thin, with deep black patina, and with the traces of lacquer (urushi). This may indicate that this tsuba belongs to Ōnin school and dates at least to late Muromachi period, ca. 1550, if not 1450 AD. Mid to late Muromachi period (ca. 1450-1550). Dimensions: 84.3 x 83.2 x 3.2 mm "In Japan, the Wheel-of-the-Law is an attribute of such deities as  Senju Kannon, the Thousand-Armed Kannon, and Dainichi Nyorai, the principal deity of Shingon Buddhism [Merrily Baird]. May be used as a family crest (mon).

  • Iron tsuba of round form with dam-shaped rim (dote-mimi) pierced with hitsu-ana and two udenuki-ana (probably cut later on) decorated in flat inlay (hira-zōgan) with vines and symbols of thunder or lightning (possibly - family crest, mon). Hitsu-ana and nakago-ana with copper sekigane.

  • Heianjō tsuba, carved and inlayed in brass with a somewhat primitive design of rocks, plants, and waves, and a man in a boat beside two jakugo stone baskets on the face and a religious structure (stupa, grave stone) on the reverse. Muromachi or Momoyama period.

    The Carlo Monzino Collection of Japanese sword fittings and swords (Sotheby's, London, 18 June 1996. p. 12-13) №9 provides an illustration of the similar tsuba with the following description: Heianjo tsuba, carved and inlayed with rocks, plants, and waves, also pierced with a jakago [sic] (stone basket).

    Gary D. Murtha in his Japanese sword guards Onin - Heianjo - Yoshiro (GDM Publications, 2016) on page 53 shows a look-a-like tsuba (though, with a kogai-hitsu-ana) with the follwoing description: Iron, 77 mm, tsuba with brass tree, snake, jakugo baskets, and curved brass pieces (representing water flowing over rocks). Buddhist halo to reverse. Although showing Onin traits, a Shoami Heiamjo attribution would fit better. Azuchi-Momoyama period.

  • Tsuba of chrysanthemoid form (kikka-gata) with yamagane core and woven copper wire pattern. Copper sekigane. Shingen school. Height: 70.2 mm; Width 67.2 mm; Thickness at seppa-dai: 3.4-3.6 mm, overall 7.3 mm. Weight 82.7 g Inscription on the wooden box reads: "Muromachi period Mumei Zōgan Shingen Tsuba" Muromachi period, 16th century. Age attribution is based on the fact that the core is made of yamagane; later copies of Edo period are usually made of iron. This small and light tsuba was likely mounted on a combat sword, while larger and much heavier woven wire Shingen tsuba of Edo period were of purely decorative purpose. http://varshavskycollection.com/shingen-tsuba/
  • 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)
  • An iron tsuba of 12-lobed form with alternating four solid and four openwork areas, each with a central bar. Symbolism remains unclear, possibly - a gunbai, i.e. military leader's fan. The solid parts decorated with 5 to 6 rows of brass dots of nail heads inlaid in ten-zōgan. The center of the plate as well as the sukashi elements are outlined with brass wire. The kozuka-hitsu-ana seems original. Muromachi period. Dimensions: 77.9 x 77.5 x 3.2 mm.
