Absolutely no, I can see when someone knows or don't know. You are far from being in this case. I have no reason to be modest. I know my limits, and you have a very long way to go before you reach them. Am I clear enough?

I don't think Lewis wrote that in the sense that you mean (I'm starting to know him quite well). If that is indeed the case, it's completely pointless. Now, you're right about one thing: I shouldn't have responded to you.

You didn't understand that it was a bit ironic; these characteristics are not exclusive to Shintogo Kunimitsu, far from it.

Are you sure ?

Ippei Yasuyo is a big name of Satsuma. Unfortunately this sword is gimei.

Let's be clear, this is not a kikumon but an Eda kikumon 'not well made).

Mei reads IZUMI NO KAMI FUJIWARA KINMICHI Gimei, kanji Rai 来 Is missing

From M Sesko Nihonto meikan translation Aritsugu (有続), Genbun (元文, 1736-1741), Settsu – „Sesshū-jū Jinrikumaru Aritsugu“ (摂州住神力丸有続), „Jinrikimaru Aritsugu“ (神力丸有続), civilian name „Takayanagi Shōzaemon“ (高柳庄左衛門), son of Kaga no Kami Sadahiro (加賀守貞広), Settsu-Shimosaka group, he signed firstwith „Kunitsugu“ (国継), there exists a joint work under the name of „Kunitsugu“ with his father Sadahiro which is dated with the first year of Shōtoku (正徳, 1711) and gives the age of 27 years, notare-midare or an Ishidō-like midareba, wazamono

The length of swords has always followed the evolution of combat techniques (tachi versus katana) and the regulations issued by the shoguns. The vast majority of tachi were suriage so that they could be used as katana. Indeed, given the price of these weapons, it was better to shorten them than to make new ones.

Humm... NBTHK is not a government organization. https://www.touken.or.jp/english/aboutus.html

Regarding a possible restoration, keep in mind that a thickening file has not yet been invented and that polishing can permanently ruin this blade which already seems quite worn to me..

Because of the bohi, which shows that this sword is ubu, I think the wakizashi is Muromachi, as there were no shinogi zukuri wakizashi before this period. ps take what Rivkin says with two grains of salt.

Obviously gimei, NBTHK oshigata (same sword the one Ray posted)

Old papers = no papers, whatever some people may say
