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.

According to seller, Owari School. Haynes writes that most tsuba of this design are Owari (Tsuba. Aesthetic Study). Unsigned. Edo period. According to F.

Iron tsuba of almost round form with a brass outlined circular opening (sukashi) in the bottom adorned with the Myriad Treasures [takaramono, 宝物] and winter motifs inlaid in cast brass (suemon-zōgan); hitsu-ana possibly cut later, both plugged with shakudo, nakaga-ana fitted with copper sekigane. According to Merrily Baird^*) (2001), the symbolism of Myriad Treasures “is associated with the Seven Gods of Good Luck, who carry them in a sack”. Among the treasures, which are said to ensure prosperity, long life, and general good fortunes, are (reading clockwise from the top):

1. Sake set [shuki, 酒器], namely flask, ladle, and cups
2. Cloves [choji, 丁子]
3. Purse of inexhaustible reaches [kinchaku, 巾着]
4. Magic mallet [kozuchi, 小槌]
5. Key to the storehouse of the Gods [kagi, 鍵]

Then, Pine, Moon, and Bamboo (see below);

7. Rhombus, or Lozenge (hosho, 方勝), with the second ideograph meaning victory.
8. Sacred (or wish-granting) gem, or jewel [hōju, 宝珠]
9. Hats of invisibility [kakuregasa, 隠れ笠]

The Myriad Treasures is carried by the Seven Gods of Good Luck (a.k.a. the Seven Lucky Gods or Seven Gods of Fortune [shichifukujin, 七福神], who are transported by the Treasure Ship [takarabune, 宝船] during the first three days of the New Year. Pine, Moon, and Bamboo: bamboo [take, 竹] and pinecones [matsukasa, 松笠], or pine [matsu, 松] – two of the Three Friends of Winter [shōchikubai, 松竹梅] – symbolize fidelity, fortitude, steadfastness, perseverance, and resilience. The third ‘friend’  – plum, [ume, 梅] – in this case replaced by the Moon [tsuki, 月] – large (11 mm) circular opening at 6 o’clock; the three small carved dots represent the dewdrops. The other side is decorated with an arabesque (karakusa) of cloves and vines, with carved dots (dewdrops) along the rim. The overall New Year / Winter connotation of the tsuba is clear. The prominence of the Moon conveys purity, coldness (sadness/loneliness), and slenderness – the inherent qualities of a samurai. H: 93 mm x W: 90 mm, thickness 4.2 mm at the centre, slightly tapered towards the rim. *) Merrily Baird.
