[ Highlight ] In the form and jiba, it remains Kyo taste, so that it is agreeable attributed to Chikushi Ryokai. The sword should not be younger than the middle age of Muromachi. For mune side of mekugi-ana at omote of nakago, there is small part where the color of rust is different from the other. It can be read as Rai Kunitoshi, as past mei, by detailed observation. The deletion of mei is looked halfway,
but, even partially, it tells deep, soft, gloss rust color and
shallow and simple yasurimes. Above all, the intention can be observed that the thickness of nakago would not be reduced further. It makes a favorable impression. There are many points to be researched on Chikushi Ryokai. There is a theory that they survived by the protection of Ô-uchi clan evacuating from the war of Ô-nin in Kyoto, on the other hand, other theory said they were invited by powerful family of Ô-uchi in west province. It shows great interest.
[ Conditions ] Not brand new polishing, with fine flaws. There is a little pale rust which is hard to see by naked eyes. They do not prevent the appreciation. It can be appreciated and conserved as it is.
