This example is just a follow up to the small Heianjo ttsuba posted about a week ago.
The reason is to illustrate the trouble and effort some inlay craftsmen or women would go to in creating accurately, regular channel widths, depths and designs- even over the mimi from one side to the other for goodness sake.
These are not necessarily appealing to everry collector but they are certainly intriguing designs. The pattern here is 'sayagata-mon' I believe Ford called it and to my way of thinking it is a monument to the skills of the Tsuba making fraternity.
More so for mine, if we accept that the plate may be Momoyama or early Edo.
Just another of the many,many facets of Japanese Tsuba craftsmanship as well as it's great artistic pieces.
