Iron tsuba of round form decorated with floral motif in brass or copper inlay (suemon-zōgan) and family crests (mon) in small openwork (ko-sukashi). Occasional brass dots or nail heads in brass ten-zōgan. Sukashi elements outlined with inlaid brass wire. Seppa-dai outlined with rope-shaped brass wire (nawame-zōgan); kozuka-hitsu-ana outlined with scalloped brass wire. Ōnin school. Mid to late Muromachi period, 15th or 16th century. Height: 88.9 mm; Width: 88.5 mm; Thickness at seppa-dai: 2.9 mm. Family crests (mon) in openwork: cherry blossom (sakura) - kamon of Sakurai and Yoshino clans, four-section lozenge (waribishi) - kamon of Takeda clan, the seven stars of the big dipper (maru ni nanatsuboshi) - kamon of Chiba clan, two encircled stripes (futatsubiki) - kamon of Ashikaga clan. Brass inlays represent flowers, branches and leaves, as well as halved plum blossom, halved chrysanthemum blossom, cloud, and chrysanthemum-on-water symbol - the mon of Kusunoki Masashige. Abundance of family crests of so many powerful warrior clans symbolizes heritage. "The brass trim around the kozuka hitsu-ana andd the seppa-dai are characteristics of Onin work" [Japanese sword guards. Onin - Heianjo - Yoshiro. Gary D. Murtha. GDM Publications, 2016; p. 27.]

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 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.    

The thin iron plate of round form and black colour carved in sukidashi-bori with the design of rocks, waves, bridge, mountain pavilion and 5-storey pagoda under the moon, on both sides, alluding to Todai-ji temple in Nara. Slightly rounded rectangular hitsu-ana probably pierced later. Very narrow raised rim as usual in katsushi tsuba. In a modern wooden box.

Late Muromachi period, 16th century. Dimensions: 81.1 x 79.5 x 3. mm (seppa-dai), 2.2 mm (base plate), 4.4. (rim).

Reference: “Art of the Samurai” on page 232, №140: ”Kamakura tsuba with Sangatsu-do tower and bridge. Muromachi period, 16th century. 83 mm x 80 mm. Unsigned. Tokyo National Museum. The mountain pavilion and bridge carved in sunken relief on the iron tsuba – both part of Tōdai-ji, a temple in Nara – are detailed in fine kebori (line) engraving. As a result of the chiselling used to create the relief, the ground of the piece is relatively thin”. Also page 41 in Tsuba Kanshoki. Kazutaro Torogoye, 1975 [LIB-1480.2018].

This tsuba is very much similar to TSU-0384.  

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 mokko form (quatrefoil) decorated with a pair of cherry blossoms (sakura) in small openwork (ko-sukashi) and inlaid in brass (suemon-zōgan) with designs of waves, distant pines, chrysanthemum flowers in halves, tendrils and leaves, lightning or thunder symbol (inazuma), flying geese and family chrests (mon): two interlocked rings (wachigai) on the face, and three encircled stripes (maru-no-uchi-ni-mitsuhikiryo) - kamon of the Kikkawa clan  - on the reverse. Hitsu-ana outlined with inlay of brass wire. Surface treated with lacquer. Copper sekigane. Though some consider this type of tsuba to resemble Heianjo school, “...the brass trim around the hitsu-ana is a characteristics of Ōnin work” [Japanese sword guards. Onin – Heianjo – Yoshiro. Gary D. Murtha. GDM Publications, 2016; p. 27.]. The Ōnin origin is reinforced by scattered ten-zōgan elements here and there through the plate. It is possible that the tsuba was initially of round form and later trimmed to mokko shape. Mid Muromachi period; 15th century. Dimensions: Height: 87.2 mm; Width: 87.9 mm; Thickness at seppa-dai: 3.6 mm.
