• 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.

  • Iron tsuba of oval form carved and inlaid in gold and copper with cormorant fisherman in disguise. Unsigned. Dimensions: 67.7 mm x 61.5 mm x 3.8 mm (at seppa-dai) Edo period: 18th century. "Since Nara period, Japanese fishermen in small boats have used cormorants (u) to catch river fish at night, binding the necks of the birds so that the fish are not swallowed. [...] The bird and the work it performs are symbols of selfless devotion to one's master and keen eyesight." - from Merrily Baird. Symbols of Japan. Thematic motifs in art and design.
