PROBABLY 18TH CENTURY
The solid iron plate of nearly round shape and convex surface. Both the front (omote) and the back (ura) are framed with a decorative overlaid band of damascened silver applied to a crosshatched, chisel-roughened ground. This decoration consists of rune-like characters, which may be or aspire to be actual language (possibly Korean) or may simply be pseudo-characters, made to look like language. The tsuba is pierced with two holes, or hitsu-ana, which have been plugged in shakudo alloy. The front of the tsuba features chiseled symmetrical decoration of dragon-like beasts framing a sacred pearl or orb. The back features a decorative cloud pattern, and the edge of the plate shows traces of gold damascening.
