From Aoi Art : The Jigane of this sword is very nice, it looks clear and bright with Utsuri apparent but there’s Kitae-ware unfortunately.
Unfortunately this blade has some Kizu but we think it’s inevitable considering the fact that the sword was made over 500 years ago. but the shape of the Nakago remains almost unchanged.
The Koshirae is themed on plants, looks good.
