• Iron tsuba of mokko form decorated with brass flat inlay (hira-zōgan) all over on both sits and going over the rounded rim. Black patina, well-forged iron. Hitsu-ana outlined with brass inlay. Former owner's catalogue number in red paint reads 25-17-61. Gary D. Murtha provides detailed account of this type of tsuba in Japanese Sword Guards. Onin-Heianjo-Yoshiro book on pages 118-122. He calls this type of tsuba "Heianjo Mogusa Tsuba": "The term mogusa is commonly used for an inlay design that represents an aquatic weed, similar to a duck weed or sago plant, which is known to quickly invade and overtake bodies of water. [...] Perhaps the visual image has some cross-over meaning for samurai in that, like the plant, a small aggressive samurai force could conquer a larger foe/area." I tried to find any reference to "mogusa" in literature, - to no avail. Neither on the vastness of internet, including Wikipedia... I did find the "duckweed" (one word), but visually it has nothing to do with the pattern on tsuba. "Sago plant" probably stands for 'Sago palm", and there is some very distant reminiscence in the construction of the sago palm leaf and the said design of inlay, but I would not go that far. In the old catalogues, such as Naunton and Hawkshaw collections, this pattern as called "sea weed" and/or "conventional fir". I will stick to these descriptions, tested by the time, and leave the enigmatic "mogusa" alone. Obviously, this type of tsuba has transformed into Yoshirō tsuba, both in Kaga province and Bizen province. Momoyama period (ca. 1660). Dimensions: 74.5 x 73.7 x 4.4 mm.

      Unsigned. However, this tsuba may be (though with reservation) attributed to Misumi Kōji school. There is some information regarding this master(s) in Tsuba. An aesthetic study by Kazutaro Torigoye and Robert E. Haynes (from the Tsuba Geijutsu-kō of Kazataro Torigoye. Edited and published by Alan L. Harvie for the Nothern California Japanese Sword Club, 1994-1997) on pages 163-4, though I was not able to locate the tsuba in the original publication. Possibly, this fragment of the book was added by Robert Haynes. Markus Sesko speculates about Misumi in his The Japanese toso-kinko Schools.// Lulu Inc., 2012 on pages 374-5: "Misumi Kōjo Tsuba. Iron plate, elliptical shape, shakudō takabori suemon, yamagane fukurin. Centipede." But of course, visual similarity does not prove anything. I was not able to find any traces of signature or a triangle on the seppa-dai.

  • 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 (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" () or the character "Chi" (知) for "Chisokutei" to identify them as copies.
