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/

A circular iron tsuba with a design of three monkey toys (kukurizaru) in small openwork (ko-sukashi); the plate further decorated with four rows of brass dot inlay (ten-zogan). The center of the plate and the openings are outlined with brass wire. Copper sekigane. A few dots missing. Muromachi period. Dimensions: 89.0 x 88.2 x 2.9 mm. Kukurizaru was an often used motif on old tsuba. The symbol has two explanations: (1) "upright" monkey, a sort of roly-poly toy, alludes to 'never-ever give up' property of the samurai; (2) monkeys are represented with their hands and feet tied to their back to symbolize self-control. Other examples of the same design:

Round iron plate of grey colour decorated in low relief (sukidashi-bori) on the face with sea waves (both layered waves, seigaiha, and rough waves, araumi), sago palm (cycas revoluta, sotetsu), presumably orchid leaves (ran) - five of them - hanging from the above, and  reeds (ashi), and on the back with waves (seigaiha only), rocks, chrysanthemums (kiku), clove (chori), reed, and presumably orchid leaves - three of them - hanging from the above. The kozuka-hitsu-ana was probably cut later. The plate is lacking the raised rim, typical for the kamakura-bori school. Muromachi period.  Dimensions: Height: 76.8 mm, width: 76.1 mm, Thickness at seppa-dai: 3.3 mm, at rim 2.0 mm. Height of nakago-ana: 29 mm. Weight: 82.4 g. NBTHK certificate № 402152: Hozon - "Worthy of preservation". A similar (most probably the same) tsuba is illustrated and described at Butterfield & Butterfield. IMPORTANT JAPANESE SWORDS, SWORD FITTINGS AND ARMOR. Auction Monday, November 19th, 1979. Sale # 3063 under lot № 66. It describes the piece as following: “Kamakura bori work of the Muromachi period. Round thin plate with some small iron bones in the edge. Carved with design of plants (sego palm) rocks, and waves on the face. The back has half of two chrysanthemums, waves, clove, and sego palm leaves. The kozuka-hitsu has been added and later enlarged. A good typical example without the rim most have. Diameter: 7.7 cm., thickness 2.5 mm. Estimated price $100-200":

Iron tsuba of round form with design of lattice (kōshi-mon, 格子文) cut in openwork (sukashi), with low relief shallow linear carving along the bars. Well forged plate with brown-ish hue. To the right of nakago-ana there is a clear inscription of the character Shō (正), which is explained by Markus Sesko is follows: "The Shinsa obviously recognized more from the signature when having the tsuba in hand, i.e. they were confident to say it is signed "Shōami" but the rest is illegible (ika-fumei, 以下不明). That is, if they were just able to read the first character SHŌ (正) and saw that there were two more, most likely A (阿) and MI (弥), they would have put those character in boxes on the paper. Boxes around characters namely means that the character is not 100% legible but it can be assumed what it is." Momoyama or early Edo period. Dimensions: 85.9 mm diameter, 3.6 mm thickness at seppa-dai. Weight: 79 g. NBTHK certificate № 425069 with attestation: Hozon - "Worthy of preservation". A similar tsuba is presented at Japanese Sword Fittings from the R. B. Caldwell Collection. Sale LN4188 "HIGO". Sotheby's, 30th March 1994, №15. The description says: "A rare early Kamakura-bori tsuba. Nambokucho period (late 14th century). Of circular form, the dark plate carved and pierced with a gate design, the struts with double engraved lines. Unsigned. 8.5 cm." The lot was sold for 1,840 GBP. We have two possible explanations of the discrepancy between Sotheby's and Shinsa/Sesko attribution: 1) either Sotheby's or Shinsa/Sesko were wrong in their attribution or 2) these are two different pieces, one - Kamakura-bori from the 14th century and another - Shōami from 16th/17th century. Anyway, I would consider my piece as a Shōami tsuba of Momoyama - early Edo period, just for the sake of modesty.
