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

Myoju was the son of Umetada Myōkin Shigetaka 埋忠明欽重降 who was the teacher of shodai Tadayoshi.

That's right.

Who is the polisher ?

This perfectly demonstrates that it is sometimes difficult even for true experts to attribute a sword. So when I read certain self-proclaimed experts, I can't refrain laughing and think that Einstein was absolutely right about infinity.

There were 2 Hasebe Kunishige, the second worked around OEI

I should point out that I am referring to Chumon-uchi mono produced by skilled smiths (those showed in literature), not kazu-uchi mono or swords forged by obscure craftsmen.

I would like to add that the shape of the nakago does not correspond to what Kiyomitsu was doing at that time (and that's not all...). https://www.toukenkomachi.com/index_ja_tachi&katanaA040425.html

So what? Just because it's in the Compton collection, does that mean it has to be soshin? All Bizen Osafune swords with a nagamei and an ubu nakago have a nengo, since OEI.

Does the person I made laugh have a valid point to make?

No nengo = gimei....

Mei (signature) is fake for sure but i can't say without having the sword in hands if it's a true nihontöt or a gunto (I do not have the power of divination).

Does the Kiyomitsu have a nengo ?

Ok, the machi is in better condition than I thought. however, I don't see why it would be machi-okuri.

IMHO this sword is a kazu-uchi mono pretty tired (look at the machi).

Shodai, this is visible in his way of writing kanji kin 金.

Brandolini's law.... How many swords from this swordsmith have you really held in your hands? Me, only one so i keep my loud mouth closed on the subject
