Iron tsuba of round form decorated with design of pine tree mushrooms (matsutake) in openwork (sukashi). Hitsu-ana of elongated oval form. Raised rim (mimi) with iron bones (tekkotsu). Copper sekigane.

Size: 84.5 mm x 85.1 mm; thickness: 3.0 mm (center), 5.6 mm (rim).

Mid Muromachi period, 15th century.

The shape and width of the rim, as well as the shape of the hitsu-ana, argue for earlier Muromachi. Tsuba is slightly wider than high, that might suggest middle of Muromachi age. According to Robert Haynes, circa 1450-1500.
