Iron tsuba of round form pierced (sukashi) in a chessboard fashion and decorated with linear (sen-zōgan) and cast (suemon-zōgan) brass inlay, including symbols of the swastika, flower-lozenge, maple leaf, pine needle, etc. on both sides; rim and openings outlined with brass inlay. Nakagō-ana plugged with copper fittings (sekigane).

Momoyama period. End of the 16th - beginning of the 17th century. Dimensions: Diameter: 75.5; Thickness: 4.5 mm.  

Mukade-zōgan tsuba with two types of wires. Iron, inlaid with brass and iron wire fastened to the surface with metal staples (mukade-zōgan); Brass inlay around the rim. 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, 16^th 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.] Height: 85.8 mm; Width 86.2 mm; Thickness at seppa-dai: 4.3 mm. Weight 177.6 g. Early Edo, 17th century. http://varshavskycollection.com/shingen-tsuba/

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.

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.

Ko-kinko ymagane cast tsuba of oval form 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 2.7 mm wide. Possibly, early Mino (ko-Mino) school. Size: 66.6 x 59.9 x 4.0 mm. Some connoisseurs believe that this kind of tsuba was in mass production at the time. Small animal believed to be a fox, however some attribute it to a long-tailed rabbit or a squirrel. I am leaning towards the rabbit. Similar example is found at Robert E. Haynes Catalog №3, April 9-11, 1982 on page 11, under № 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. The only difference betwen my tsuba and his is that his has a square hole on the right shoulder of the seppa-dai. Early Muromachi (if we follow Robert it is even Nanbokucho, 1337-1392) or Momoyama period. The Momoyama attribution is mostly based on a fact that “waves and rabbit” motif became most popular in Momoyama times. Mokkōgata tsuba of similar design in this collection - see TSU-0282.  

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).
