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.

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. The thin, six-lobed iron plate is carved on each side with a wide groove that follows the shape of the rim, and with six scroll lines and a single thin circular groove. […] The hitsu-ana was added at a later date, circa 1500-1550.  Height 8.3 cm, width 8.6 cm, thickness 2.5 mm. The tsuba was initially intended  to be mounted on a tachi of the battle type in use from Nambokucho to early Muromachi period (1333-1400)”. Sold at $935. And another one in Robert E. Haynes Catalog #9 on page 24-25 under №23: R.E. Haynes description: “Typical later Kamakura-bori style work. This type of plate and carving show the uniform work produced by several schools in the Muromachi period. Some had brass inlay and others were just carved as this one is. The hitsu are later. Ca. 1550. Ht. 8.8 cm, Th. 3.25 mm”. Sold for $175.    

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 with design of rudder, paddle, and stars in small openwork (ko-sukshi) outlined with brass wire, and further decorated with inlay of five concentric rows of brass dots or nail heads (ten-zōgan) and circular brass wire inlaid inside the innermost row of dots. Two lower round openings may also serve as udenuki-ana. Copper sekigane. Unsigned. Late Muromachi or Momoyama period, 16th century. Diameter: 90.4 x 89.8 x 2.8 mm.

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 with design of butterfly (left) and dragonfly (right) in openwork (sukashi), outlined with brass wire. Thin plate also decorated with five concentric circular rows of brass dots (nail heads) in ten-zōgan; brass wire outlines of the center 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. Reference to the design has been found at "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...".

Iron tsuba of four-lobbed mokkō form decorated in brass and shakudō inlay on the face with design of rotten skull, fly, maple leaf, pine cones and needles, and on the back with design of rotten skull, wild boar, pine cones and needles. Scattered brass dots on both sides. Hitsu-ana possibly cut off later. Surface has traces of lacquer (urushi). Momoyama period. Dimensions: 67.3 x 61.5 x 4.3 mm A similar example can be found at Tsuba Kanshoki by Kazutaro Torogoye, 1975 on p. 61: "Heianjōzōgan tsuba. No sig. Iron: Pine-cone, seeds, ants & rock, brass zōgan. Kakumimi: C. 1.5 bu. Age: Momoyama. Sup. - Early work. Interest."

Two ymagane tsuba (daisho) with chiseled diaper pattern of waves. The larger tsuba (dai) is of mokkō form with a wide (4.6 mm) polished rim (fukurin?). Water spray is realized in copper ten-zōgan. Size: 75.0 x 71.6  x 3.2 (center), 4.0 (rim) mm. Copper sekigane. The smaller tsuba (sho) is of oval form, without a rim. No inlay. Size: 53.2 x 45.5 x 4.1 mm. Ko-kinko school. Muromachi period. In Kokusai Tosogu Kai; 5th International Convention & Exhibition, 2009 on page 51 under № 5-U8 there is a piece from George Gaucys collection, described as follows: Unsigned Tachi-Kanagushi tsuba, Yamagane base. Nami (wave) motif. Circa: Muromachi period (15th century). 6.88 x 6.81 x 0.45 (rim), 0.36 (center). The classic wave form is typically seen in Muromachi period tosogu. The patina is rich and rustic, which presents history and warmth. This tsuba may be interpreted as either tachi-kanagushi or ko-kinko work. Early tachi tsuba were symmetrical in design and also not very sophisticated, Design elements filled in up to seppadai as the waves do in this tsuba. There is a simple fikurin of the same metal and it is flat to the plate. On the ko-kinko side, the crests of the waves show more complexity than tachi works and less symmetry. A very intriguing tsuba from late Muromachi period."

Iron tsuba of mokkō form decorated with inome (wild boar's eye) in openwork (sukashi) outlined with brass wire. The plate decorated with 3 concentric circular rows of brass dots in ten-zōgan. Center of the plate outlined with the inlaid circular brass wire (sen-zōgan). Some dots and the outline of inome on the face are missing.

Ōnin school. Unsigned. Mid Muromachi period, middle of the 15th century. Dimensions: 72.1 x 71.3 x 2.3 mm.
