Yeah Alex i understand, and not only for blade made 300+ years ago but in shinshinto too...probably many blades was made by student... and maybe if the blade was good the main smith put his signature...
The problem is that the most expert (shinsa) can made valutation error too. I think many of the forum members read Nakahara's book and what he said about paper, mumei blade and gimei.
I'm sorry if i jump to call it fake, but at first look it seems chinese. At second look probably real nihonto but in this condition Adam is very difficult to say something about history, date or other things. From the pics i don't know if the blade worth the money of professional polishing.
If you have the possibility to take it to a togishi for a judgement, is the best to do.
Jean i understand but if a beautiful shinshinto blade, signed and with a correct price, i don't mind if have a little suriage or if will not take a paper...
And sorry ken...but i mean the ww2...is not a war? Why when someone don't know what are saying start with the story of caretaker...this make me smile...please...
Last thing, really nobody in Japanese history cut a little piece of nakago to fit in a particular koshirae? Really??
Yeah Jean, i told that for me is not important the paper, and i don't want to resell nothing, i don't contest anything, i only say that there is some beautiful shinshinto blade with a little suriage made for fitting to another koshirae or a military mounts, sincerly i prefer a splendid shinshinto blade with a little suriage and with mei...than a mediocre blade with ubu nakago but mumei...
Blades made in Meiji and Taisho periods, and those by recently deceased smiths, can receive Hozon paper only when the blade is well made, zaimei and has a ubu-nakago. Edo and earlier blades with correct mei, or mumei blades on which the time period, kuni and group can be identified, may receive Hozon paper.
Oh i red the shinsa standard, and i'm glad to know that my beautiful shinshinto blade with an authentic and beautiful mei, but with a 1 cm suriage nakago can't take the hozon paper, while a late edo mediocre mumei blade but with the only important thing, ubu nakago, can take it.
Jean, about what you say,i must buy a sword of any smith of any quality, muromachi, shinto or shinshinto and the only rule is an ubu nakago? And sorry but i don't need a certificate for the quality of the blade.
