I bought in AUCTION this blade 2 weeks ago and today it is in my hand.
It is from Edo period (first or middle), "shinto".
I think the first KIZU is a "fukure" and the second KIZU it is "jiare", but your opinion it's important.
About the strange color of top of blade (it'a a "Iori-mune" with "V" up) I don't know
