Iron tsuba of round form with a Marsilea (water clover, paddy plant, denjiso) in openwork (sukashi) and a cricket carved in low relief (katakiribori) with extremities and one antenna inlaid with brass; the other antenna is carved in kebori (which antenna is inlaid and which is carved alternates on the face and on the reverse). The plate decorated with vertical file stroke ornamentation (tate-yasurime). Raised dam-shaped rim (dote-mimi). Inscription from a previous collector in red oil paint: 22-71-1. Edo period, possibly 17th century. Katchushi school.

Size: 75.0 x 74.4 x 3.6 (center), 5.0 (rim) mm.

The plant Marsilea (paddy plant, denjiso), common names include water clover and four-leaf clover because the long-stalked leaves have four clover-like lobes and are either held above water or submerged. In The elements of Japanese design by John W. Dower, this motif is listed under the numbers 634-35 Paddy Plant (denjiso). Obviously, as a four-leaf clover it is an auspicious symbol. The four leaves radiate out as the shape of the kanji 田 (romaji 'ta'), which means 'rice paddy'. This symbol may be used as a family crest (mon), and this would be the most probable explanation of the sukashi on this tsuba.

Here is what Markus Sesko wrights in his book The Japanese toso-kinko Schools, 2012, on page 374:

An artist who worked in the style of the Shimizu-Jingo school was Chisokutei Amatsune (知足亭天常). He was actually a samurai from Yatsushiro who made tsuba as a sideline. An extant old hakogaki of one of his pieces mentions that he died in Edo in the sixth month of An'ei eight (1779) at the age of 73. But the era of An'ei is probably wrong because Chikokutei (sic) is today dated by most experts around Tenpō (1830-1844). His relationships with the Shimizu school or under which Jingo master he had studied are unknown. From the point of view of production time and the finishing of nakago-ana, he is rather associated with the 5th and last gen. Shigenaga who died in the seventh year of Kaei (1854). A peculiarity of  Chisokutei was that he signed his Jingo copies with  "Yatsushiro Jingo Saku" ([八代甚吾作) but added the small syllable "chi" (チ) or the character "Chi" (知) for "Chisokutei" to identify them as copies.

Copper tsuba of oval form carved in kebori and katakiribori with Tekkai Sennin sitting under bamboo on the face and with a pine tree on the back. Ishime-ji treated surface.

Signed on the reverse: Jōi (乗 意).

Edo period (First half of 18th century). Dimensions: 69.6 x 66.5 x 4.5 mm Sugiura Jōi (杉 浦 乗 意) was a master of Nara School in Edo; he was a student of Toshinaga [M. Sesko, 'Genealogies', p. 32]. "Sugiura Jōi (1701-1761) made many fuchigashira and kozuka, tsuba are rather rare." [M. Sesko, The Japanese toso-kinko Schools].

This tsuba is a cut from a typical Bizen Shōami butterfly tsuba (see TSU-0100 in this collection), which normally would have had a circular rim around the butterfly. In this particular example of altered guard we have both eyes of the insect (inlaid in brass or copper) intact. The kebori carving is more pronounced than in TSU-0100 example. Copper sekigane. Unsigned. Attributed to Bizen Shōami school, early Edo period (17th century). Dimensions: 64.7 x 63.7 x 5.2 mm References: see TSU-0100.

Reference to Hawkshaw Collection [Plate VII] happened to be not exact; it is Plate VIII, №236. It is clearly not the Hawkshaw piece (different facial expression, signle hitsu-ana, no plug. Description at Hawkshaw, 1910, reads: Iron, in the shape of a man's head, severed at the neck, the forehead in three wrinkles, the mouth hard-set and drooping, the eyes open, inlaid brass with shakudo pupils. Signed: Shoami; dated second year of Shoho, first month [SV: December 1644 through February 1648].

Iron tsuba of round form decorated with eight roundels - circular emblems of flowers and/or family crests (mon) made of cast brass, pierced and chiseled in kebori, and with flat brass inlay (hira-zōgan) of vines or seaweed all over the plate. Hitsu-ana outlined in brass. Four positive silhouette roundels are 3-, 4-, 5-, and 6- pointing crests/flowers; four negative silhouette roundels are bellflower, cherry blossom, and suhama.

Gomoku-zōgan tsuba. Iron, inlaid with brass scrap (gomoku-zōgan), and polished. Height: 75.3 mm; Width 74.9 mm; Thickness at seppa-dai: 3.6 mm. Weight 130.2 g. Edo, 18th century. Gary D. Murtha dedicates 10 pages to this type of tsuba: "...they were made by soldering brass overlay scraps to the iron plate". Actual gomoku-zōgan tsuba are seldom found in collections most likely because they have little if any artistic attributes. In addition, many have rough surfaces making them questionable for use on a sword. It is said that many of these were produced in Yokohama for export to the West during the late Edo period". G. D. Murtha then describes the technique of making gomoku-zōgan in every detail, and states that "The brass pieces are said to represent 'fallen pine needles', a description most likely created to add aesthetic value to help market the tsuba" [see:Gary D. Murtha. Japanese sword guards. Onin - Heianjo - Yoshiro. GDM Publications, 2016; pp. 160-161].

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.

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/

Shingen school (or style) tsuba of round form with an iron core of spoked-wheel shape, with its centre covered with a copper plate decorated with star-shaped punch marks. From this copper plate outward, the body is formed by brass and copper wire (flat and twisted) in a weave pattern. Both hitsu-ana are outlined in brass with a raised rim. Copper sekigane. Unsigned.

Citing "JAPANESE SWORD-MOUNTS IN THE COLLECTIONS OF FIELD MUSEUM" by Helen C. Gunsaulus, Assistant Curator of Japanese Ethnology. 61 plates. Berthold Laufer, Curator of Anthropology. Field Museum of Natural History, Publication 216, Anthropological Series, Volume XVI; Chicago, 1923; p.45: "An unusual group of tsuba popular in the late sixteenth century and afterwards is made up of those guards known as Shingen tsuba, a name which was derived from a sixteenth-century warrior, Takeda Shingen (Takeda Harunobu, 1521-73), who is said to have preferred this style of guard, as it combined strength and lightness. Under the category of "Shingen", four different types abd generally listed, though a fifth appears in the drawings in the Boston Catalogue of Okabe Kakuya "Japanese Sword Guards" (p. 21). It is square, that form which is said to have been used in Ashikaga days for scaling walls, the sword having been set up as a step. [...] The following descriptions include, however, the Shingen tsuba usually met with.

1. So-called Mukade ("centipede") tsuba are made of iron in which a centepede is inlaid in brass or copper wire. Mukade tsuba of Myōchin and Umetada warkmanship have been found with the inscription, "Made to the taste of Takeda Shingen".
2. There are those of solid iron, with need centers of brass, to the edges of which is affixed a weaving of brass and copper wires which is bound to the foundation disk by a rim, usually decorated simply.
3. Another type is of solid iron, bored at intervals and laced with braided or twisted wires of copper and brass.
4. The fourth type is a chrysanthemoid form, chiselled in open work and laced or woven tightly with copper and brass wire."

I believe that my tsuba [№ TSU-0338] belongs to the fourth type. However, this particular specimen does not conform with the description of Shingen tsuba as combining strength and lightness. Its weight is 290 g, which tells us that most probably it had purely decorative function (as most tsuba in Edo period). A somewhat similar design can be found at wikimedia. A look-a-like tsuba is illustrated at Compton Collection, Part II, p.p. 26-27, №54. It is dated ca. 1700. It was in a box with Sato Kanzan inscription, and had NBTHK certificate attesttion of 'Tokubetsu Kicho'. Price realized: $5,280.
