  • Copper tsuba of slightly elongated round form carved in low relief (usuniku-bori, katakiri bori) with the design of a mythical creature: a horse, however, with divided hoofs, with anthropomorphic (human-like) face though with a vertically positioned third eye on the forehead, and a corn. Certain elements of the image accentuated with gold iroe. On the back: flowers and grasses carved in katakiribori technique. Shakudō fukurin.

    Edo period.

    Dimensions: 70.7 x 70.2 x 3.7 mm In a custom wooden box.
  • A copper tsuba with ishime-ji ground carved and polished (migaki-ji) with sitting Daruma; his eyes are inlaid with shakudo and he has a golden earring. The reverse carved with four characters: 廓 然 無 性 (Kakunen-mushō). It is a Zen proverb that goes back to Bodhidharma (Daruma), meaning "boundless expanse and nothing that can be called holy." [Markus Sesko translation]. Shakudo fukurin.

    Unsigned.

    Edo period (circa 1800). Dimensions: 68.2 x 65.5 x 4.8 (center) x 3.2 (rim) mm
  • Copper tsuba of slightly elongated round form carved in low relief (shishiaibori and sukisagebori) and inlaid in gold, silver and shakudō with the design of dreaming Rosei (Lu Sheng): he is half-sitting by the pillow with his eyes closed, holding his fan, with a scroll by his feet, surrounded by flying butterflies.

    Edo period, first half of the 18th century.

    Dimensions: 70.8 x 67.1 x 5.0 mm. Signed on the reverse: Jōi (乗 意) + Kaō. Sugiura Jōi [杉 浦 乗 意] (1701-1761) was a master of Nara School in Edo; he was a student of Toshinaga [M. Sesko, ‘Genealogies’, p. 32]. “Sugiura Jōi (1701-1761) made many fuchigashira and kozuka, tsuba are rather rare.” [M. Sesko, The Japanese toso-kinko Schools, pp. 148-149]. On Rosei (Lu Sheng) dream's legend see Legend in Japanese Art by Henri L. Joly (1908 edition) on page 293.
  • Iron tsuba of ryō-mokko-gata form decorated with a spotted deer (Nara deer or sika deer) motif in low relief carving (sukidashi-bori) and flat silver inlay (hara-zōgan); deer's eyes and details in gold inlay. Signed on a copper cartouche: Noriyuki. Grass in low relief carving on the reverse. There were two Noriyuki in Hamano school - father (Noriyuki I, 1736-1787) and son (Noriyuki II, 1771-1852). Frankly speaking, I don't know which one made this particular piece. Edo period, late 18th or early 19th century.

    Size: 71.5 x 70.0 x 3.0 mm.

       
  • 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.
  • An iron tsuba of oval form decorated with a water plantain (omodaka) carved in low relief and water drops inlaid in gold.

    Signed: Bushū jū Masamitsu.

    Bushū-Itō school.

    There were several tsuba artists with the name of Masamitsu. The one who worked with iron and spelled [正光] is mentioned at Markus Sesko's 'Genealogies' on page 106 in Akasaka School of Edo section as Masamitsu Gorōbei , student of Tadatoki, 4th generation Akasaka master. The name is not mentioned at Torigoye/Haynes 'Tsuba. An Aesthetic Study' in the list of Bushū-Itō family masters on page 181.

  • Iron tsuba of mokkō-form with a pine and a frog on the face and a snail on the back, carved and inlaid with gold. Each figurative element of the design is signed on three inlaid cartouches: Masaharu (正春), Kazuyuki (一之), and Yoshikazu (良一) [read by Markus Sesko]. Snake, snail, and frog together make a design called "SANSUKUMI" - Three Cringing Ones [Merrily Baird]. The snail can poison the snake, the frog eats the snail, and the snake eats the frog. It's unclear whether the pine replaces the snake on this tsuba, or the snake is hiding in the pine? Anyway, the frog and the snail are clearly represented. "Maybe we have here a joint work with Masaharu (the silver cartouche next to the pine) being the master and making the plate and Kazuyuki and Yoshikazu as his students carving out the frog and the snail respectively". Copper sekigane.

    Dimensions: 70.9 x 67.2 x 3.0 mm. Edo period (18th century).

    Markus Sesko writes: "I agree, the frog and the snail most likely allude to the san-sukumi motif. It is possible that we have here an artist's choice to deliberately leave out the snake, maybe he thought that the motif is already obvious and there is no need to add a snake to make it clear that the tsuba shows the san-sukumi motif." [Markus Sesko].

    Kazuyuki (一之): adopted son of Kumagai Yoshiyuki, student of Ichijō (Gotō-Ichijō Scool) [M. Sesko 'Genealogies', page 19.] Masaharu (正春): Kasuya fam., student of Masamichi (1707-1757) who was the 4th generation Nomura School master in Edo. [M. Sesko 'Genealogies', page 49.]
  • 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 round form decorated with the design of distant pines, torii, and crescent moon in openwork (sukashi). Copper sekigane.

    Size: 84.9 x 84.8 x 5.8 mm.

    Edo period, ca. 1750.

    Tosa Myochin or Akasaka school.

    Japanese Swords and Sword Fittings from the Collection of Dr. Walter Ames Compton (Part I). Christie's, New York, March 31, 1992, pp. 28-29, № 53:

    "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."

    Compton Collection, Vol. 1, №53

  • Large oval form tsuba decorated with two human figures (scholar and attendant) under the pine tree admiring a view of a waterfall on the face of the plate, and with stylized dragons carved on the reverse among the symbols of thunder inlaid in gold. The plate is carved in low relief with details inlaid with gold and silver.

    Signed: Yamashiro no kuni Fushimi no ju Kaneie [Kaneie of Fushimi in Yamashiro Province] [山城國伏見住金家], with Kaō. It is a fake signature (gimei).

    Size: Height: 91.9 mm; Width: 85.6 mm; Thickness: 3.4 mm; Weight: 169 g.

    This is a late Edo period, 19th-century export work to cater to the tastes of the European tsuba collectors. It does not have anything in common with the work of great Kaneie masters.

Nihon Art Publishers, 2010" on p. 117 says: "Brass outer plate of round shape. This tsuba has an iron core tsuba of spoke form as made by Saotome school, ca. 1500. There are brass plates on either side connected to the rim by woven brass and shakudō wire. The wire has been hand drawn, which is very difficult. The hitsuana are brass lined and the rim has a brass cover. This type of tsuba is referred to as a Shingen tsuba. This is a reference to Takeda Shingen Harunobu (1521-1573), the great and famous daimyō." For reference see the MFA collection. A look-a-like tsuba is illustrated in Compton Collection, vol. 2, p. 26-27, №52:

  • Iron tsuba of round form with design of butterfly (left) and dragonfly (right) in openwork (sukashi), outlined with brass wire.

  • 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 round form with two overlapping triangles (uroko) motif  in openwork (sukashi). Triangle patterns usually associate with 'fish scale', mon of Hojo family (and others). Edo period or later.

    Size: 71.4 x 70.2 x 5.2 mm.

    An association with the Star of David is doubtful if not impossible.  
  • Iron tsuba of round form decorated with eight roundels – circular emblems of flowers and/or family crests (mon) made of cast brass, pierced and chiseled in kebori, and with flat brass inlay (hira-zōgan) of vines or leaves all over the plate. Both hitsu-ana could have been trimmed with brass now lacking. Nakago-ana of triangular form, possibly enlarged, with copper sekigane. All typical emblems with bellflower, two variations on suhama theme, and 3, 4, 5, and 6-poinitng mon variations. A distinctive character of this tsuba is a mon at 12 hours depicting water plantain (omodaka).

    “Omodaka was also called shōgunsō (victorious army grass); because of this martial connotation, it was a design favored for the crests of samurai families” [Family crests of Japan, Stone Bridge Press, Berkeley, California]. Yoshirō school (Kaga-Yoshirō). The Momoyama or early Edo period, beginning of 17th century. Size: Height: 81.4 mm; width: 81.2; thickness 3.8 mm at seppa-dai.
  • Iron tsuba of quatrefoil form (mokka-gata) adorned with the design of stars, wild geese, blossoms, leaves and tendrils realized in the brass inlay. The inlay technique includes suemon-zōgan and ten-zōgan. A smaller opening (kozuka hitsu-ana) surrounded by a scalloped brass border. The seppa-dai bordered with linear inlay. A few dots of inlay on both sides are missing. Measurements: height 71 mm, width 70 mm, thickness at centre 2.7 cm Time: Late Muromachi (1514 – 1573)  
  • 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.

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 triple diamond (matsukawa-bishi) in openwork (sukashi). Square rim. Ko-Tosho school. Nanbokucho period: Late 14th century (Oan/Eiwa era). Height: 92.3 mm. Width: 92.3 mm. Rim thickness: 2.5 mm. Center thickness: 3.0 mm. Provenance: Sasano Masayuki Collection, № 15: "Two small lozenges are attached to each end of a larger lozenge. Most Ko-tosho tsuba have inspirational designs, however this has a rather casual appearance, although it represents the unstable political situation at the time".  
  • Iron tsuba of round form with design of rabbit (usagi) in openwork (sukashi) and inlaid with designs of plants and family crests (mon) in suemon-zōgan. A branch with lonely leaf, half chrysanthemum, and flying wild geese on the face represent autumnal connotations. The same motif is complemented by a clove (choji) on the reverse.  The family crests (mon) include: interlocked rings (kanawa; wachigai), three encircled lines or stripes (hikiryo), bit or muzzle (kutsuwa - horse's harness element with possible christian symbolism), and encircled triangle (uroko, fish scale). Brass wire trim around the openwork elements and the seppa-dai, scalloped wire inlay around the hitsu-ana. Iron is dark, almost black. Brass or copper elements vary in shades of lighter and darker yellow with red-ish hue. Ōnin school. Late Muromachi period, 16th century.

Diameter: 82.0 mm; Thickness: 2.8 mm Cited from Merrily Baird. Symbols of Japan. Thematic motifs in art and design. Rizzoli international publications, Inc., 2001, p. 72: "In Japanese art, the appearance of bamboo shoots is often without symbolic meaning. In other cases, however, the shoots are emblematic of Moso (Chinese: Meng Tsung/Meng Zong), a paragon of filial piety who dug through snow to find shoots for his mother. ... especially in miniature art forms, let bamboo shoots alone speak for the full story." The full story is this (See THE TWENTY-FOUR PARAGONS OF FILIAL PIETY [ERSHISI XIAO]):
    Tears That Brought Bamboo-shoots From the Frozen Earth: Meng Zong Meng Zong lived during the Three Kingdoms Period of China's past. His father died when he was young, and he and his mother struggled to survive. One winter his mother was stricken with a serious illness, and craved some bamboo-shoot broth as medicine. But in the depths of winter, with snow and ice blanketing the ground, where was anyone to find fresh bamboo shoots, shoots that emerge only in the warm months? Nonetheless, Meng Zong, to avoid disappointing his mother, bravely fetched his shovel and went out into the white landscape in search of bamboo shoots. In the thicket he found only frosted leaves and green stalks coated with snowflakes and ice. Look as he might, there were simply no fresh shoots growing in the winter. The thought of his poor mother lying sick on her bed, waiting for bamboo-broth medicine, made his heartache. Uncontrollably, tears began to fall in rivers to the ground beneath the tall, emerald canes. Even now, as his tears flowed down, he kept a light of faith in his heart. If he was truly sincere in his search, perhaps.... Just then Meng Zong nearly tripped and fell over a sharply protruding lump of earth. He quickly knelt down and knocked aside the dirt with his trembling fingers. How uncanny! Underneath his frozen hands he discovered a bed of fresh, tender bamboo shoots! Overjoyed, he gathered up a coatful and carried them back home. The broth that he quickly set stewing in the pot soon cured his mother's illness. The neighbors, hearing the story, exclaimed that it was the strength of his sincere, unselfish, filial resolve that inspired heaven and earth to respond, and to bring up, out of season, the fresh shoots that cured his mother's disease. Before Meng Zong's prayers generated this miracle, it was normally considered impossible for bamboo shoots to grow in the winter. After the nmiracle took place, however, people were able to gather and to eat bamboo shoots all year round. The winter variety that existed hereafter became known as "winter shoots." The villagers were deeply influenced by Meng Zong's courage and devotion. They renamed the spot where the event took place, "Meng Zong's Bamboo Grove". We can now enjoy bamboo sprouts during the winter as well, and as we do so, it is fitting to recollect Meng Zong's outstanding example of filial respect, and reflect on our conduct as sons and daughter of our parents. A verse in his honor says, His teardrops transformed winter at the roots; Up from the ice crept tender bamboo shoots. Instantly, the winter-sprouts matured; Heaven's will: a happy, peaceful world.
     
  • A very large and very thin iron tsuba of round form decorated with design of formalized butterfly and dragonfly in openwork (sukashi). The characteristics of the plate resemble those of Kamakura period ko-tōshō tsuba. However, the design seems too 'modern' to me, but it's hard to tell; it may be a late Muromachi or Momoyama period work. Tōshō or Ko-Tōshō school (or a Katchushi). Muromachi period. Dimensions: 99.6 x 100.5 x 2.1 mm. This is what Jim Gilbert says about old tsuba:
    "Traditionally the old iron plate tsuba are classified into Ko Tosho (old sword smith), and Ko Katchushi (old armor maker) styles. It is sometimes difficult to justify attribution of a given tsuba to the Tosho or Katchushi category. Generally guards with raised rims or relatively complex designs tend to be assigned to Katchushi. This is basically a convention we follow out of habit and convenience." [...] "In Token Kai-Shi part six, Articles by Akiyama Kyusaku, Robert Haynes comments: "…from 1300 to 1400 over 150,000 MOUNTED swords were made in Japan for export alone. This means that over four tsuba a day were made for 100 years. This would mean that at least 3000 persons were making nothing but tsuba, let alone all the other fittings needed to complete these swords. With sword smiths, fittings makers and all the other artists need to complete a sword for export, at least 10,000 sword artists were working together, in any one of these hundred years."

  • Well-forged iron plate of round shape (maru-gata) is decorated with water weeds or arabesque (karakusa) in flat brass inlay (hira-zōgan) all over and eight family crests (mon) of round form in cast brass with delicate linear carving (kebori) and openwork (sukashi). Crests represent: [at 9 hours] three counter-clockwise commas or swirls (tomoe); [at 10:30] plum blossom (ume); [at 12:00, 1:130, and 7:30] - stylized flower made by cutting out five suhama symblos (flower-shaped suhama); [at 3:00] bellflower (kikyō); [at 4:30] seven-star crest (shichiyō-mon); [at 6:00] cherry blossom (sakura). Brass-trimmed ryo-hitsu. Copper sekigane. Yoshirō school. Momoyama or early Edo period, end of the 16th to first half of the 17th century (1574-1650). Inscription on seppa-dai: 八幡 - Hachiman. Size: height 89.6 mm, width 89.3 mm, thickness at seppa-dai 3,0 mm. Weight 129.7 g. NBTHK certificate № 4007685, June 27, 2015: HOZON (Worthy of Preservation). As for the inscription, Nihonto Message Board blog discussion provides the following explanation of the inscription: "An expression of conviction as to being the best under the sun". On the other hand, there may be more in this confluence of symbols: the tomoe crest at 9:00 is "the kamon of Hachiman, the war god" [Family Crests of Japan; Stone Bridge Press, Berkeley, CA, 2007, p. 108]. The character 八 in the inscription cut stronger than the other kanji, and may be by a different hand in different time. 八 (hachi, eight): "The numeral eight was appreciated because its shape broadens toward the bottom, symbolizing eternal expansion" [ibid, p. 119]. It may be said that this tsuba is dedicated to Hachiman. Other crests (suhama, bellflower, seven-stars, plum and cherry blossoms) collectively allude to "good old times" when Fijiwara and Taira clans were in full bloom. Markus Sesko believes that the inscriptions reads: Hachiman: "the inscription is/was HACHIMAN (八幡), the God of War and a relatively popular inscription for tsuba, swords and armor." Elliott Long and Robert Haynes provide the following explanation of the inscription: "...hachi is correct and represents the name of the HACHI SHRINE. The inscription reads 'YAWATA' which is the name of the mountain in Mino Province where the HACHI Shrine is located". Details on Hachiman Shrine in Yawata (八幡市) can be found elsewhere, including Historical and geographical dictionary of Japan by Edmond Papinot. Van Ham auction house provides the following description: MON-SUKASHI TSUBA. MARUGATA. Japan. Momoyama period. Yoshiro school. Iron with inlays of brass.

    The design of my tsuba closely resembles the one at the last example (Sasano 1994 №280), however, the form (mine is quatrefoil) and the execution (strength) are very different, which result in a very different spirit of my piece.

Note on design: though this design resembles family crests with oak and mulberry leaves, I believe it's  a melon flower [see Jeanne Allen. Designer's guide to Samurai Patterns.

    Jeanne Allen. Designer's guide to Samurai Patterns. Chronicle Books, San Francisco, 1990. Page 114, №130.

    Note about the distribution of thickness (niku-oki): "this tsuba has toroid features, niku raises from the rim towards the centre but thins once more out when approaching the seppa-dai" [M. Sesko, "Handbook...", p. 48].
