The same interpretation of the said heart-like symbol (aoi leaf) is given at Helen C. Gunsaulus. Japanese sword-mounts in the collection of Field Museum. // Publication 216, Anthropological Series, Volume XVI; Chicago, 1923; p. 54: "This mokkō-formed tsuba recalls the aoi form, perforated as it is with the four aoi leaves." It is possible that the "wild boar's eye" theory was developed by later scholars.
There is also a theory, supported by Graham Gemmell, saying that: “In simple terms Onin works are decorated Ko-Katchushi tsuba. … But, not content with iron alone, they began to decorate it with what was, in the early Muromachi period, a rare and valuable metal, brass. The Onin workers cut the design into the iron, using narrow channels, cast the brass, piece by piece, and then hammered it into the iron plate as though they were putting together a jigsaw. When complete the tsuba would be black lacquered exactly as the plain iron ones had been, the brass shining dully through it in a way that fulfilled the goal of shibui or restrained elegance.” [Tosogu. Treasure of the samurai. Fine Japanese Sword Fittings from The Muromachi to The Meiji Period, by Graham Gemmell. // Sarzi-Amadè Limited, London, 1991. An exhibition held in London from 21st March to 4th April, 1991]. The following illustration from Helen C. Gunsaulus. Japanese sword-mounts in the collection of Field Museum. // Publication 216, Anthropological Series, Volume XVI; Chicago, 1923; pp. 43 supports the idea.
Helen C. Gunsaulus' description of the dragonfly emblem is as follows: "This motive, the dragon-fly (akitsu), is generally accepted as a symbol of the kingdom of Japan, and the origin of the idea is traced to the legend recounted in the Kojiki and Nihongo of the Emperor Jimmu's view of the island from mountain top. He is said to have thought the kingdom looked like a dragon-fly touching its tail with its mouth. From this it received its name Akitsu-shima... etc."
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.

Momoyama period (1574 – 1603). Dimensions: H: 85.5 cm, W: 79 mm, Thickness (centre): 4.8 mm. Tsuba of a similar design can be found in this collection [TSU-0373]. In that example, the plate was later pierced with geometrical mon-like openwork to resemble Koike Yoshirō's handguards. More about this type of tsuba here.

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 leaves all over the plate. Both hitsu-ana could have been trimmed with brass now lacking. Nakago-ana of triangular form, possibly enlarged, with copper sekigane. All typical emblems with bellflower, two variations on suhama theme, and 3, 4, 5, and 6-poinitng mon variations. A distinctive character of this tsuba is a mon at 12 hours depicting water plantain (omodaka).
“Omodaka was also called shōgunsō (victorious army grass); because of this martial connotation, it was a design favored for the crests of samurai families” [Family crests of Japan, Stone Bridge Press, Berkeley, California]. Yoshirō school (Kaga-Yoshirō). The Momoyama or early Edo period, beginning of 17th century. Size: Height: 81.4 mm; width: 81.2; thickness 3.8 mm at seppa-dai.
"Early signed example of the work of Koike Naomasa. The kiku shape iron plate is well finished. The flush inlay is brass, for the scroll work on both sides, with the leaves and kiri mon in brass, copper and silver with strong detail carving. Some of the inlay goes almost over the edge, which is goishi gata. The large hitsuana are plugged in lead with starburst kokuin surface design. [...]The face is signed in deep bold kanji: Koike Naomasa; the back is signed: Izumi no Kami, on the right and Yoshiro on the left. There are one or two small pieces of inlay missing. Sold by Sotheby London, Oct. 27, 1981, lot 368. Height = 86 mm, thickness (seppa-dai) = 3.75 mm, (edge) = 4 mm."Another similar example presented at: "Tsuba" by Günter Heckmann, 1995, №T55 — "Designation: Koike Naomasa. Mid Edo, end of the 17th century. Iron, hira-zogan in brass, copper, silver and shakudo, katakiri-bori. Tendrils and leaves. 87.0 x 78.0 x 4.0 mm." Reference: Japanische Schwertzierate by Lumir Jisl, 1967, page. 13. [SV: Actually, his tsuba is signed Izumi no Kami Yoshiro on the back; and Koike Naomasa on the front, exactly as Robert Haynes's tsuba. Dating this tsuba Mid-Edo, 17th century may be considered a misattribution]. More details regarding the Yoshirō tsuba.
