Still no one ? unless three people try, I'll keep the answer to myself.

My bad, i choosed a wrong example which is a later work just before changing his mei to Ikkanshi The correct one

This is the shodai but that's not where the difference lies I put a mei of the nidai so that you can try to find it.

Do you know why you want to buy this sword?

Yes.

No one to try a guess ?

I must add that it's the proximity of the end of the shinogi and the point of the kissaki that makes me think of a simple shobu-zukuri. A photo of a naginata naoshi has been posted, and it's clear that the shinogi ends far from the point of the kissaki, to avoid breaking the line of the boshi

No, the position must be seen from the smith's point of view, so there's nothing to stop him from grabbing the blade and attacking.

No, the position does not respect etiquette: the tsuka should be pointing to the left of the smith to show a sign of peace (it is grasped with the right hand).

The wakizashi is displayed the wrong way..

Yep. Open Nagayama's connoisseur page 53 ... https://ginza.choshu.../001/16_morokage.php

Another mei with the same asking. Which generation ?

Ok, Moriyama san found it, As the chart he posted shows, each generation has its own way of engraving the Tsugu character. ps Sorry for the quality of the photo, I took it a certain time ago and I no longer have access to this sword.

Yasutsugu but which generation ?

the next one will be stay a week before answer

Yes it is

Nihonto Koza afu Watson translation Shinto volume

it's written Shodai Sukehiro and now would you read carefully the page 238 and tell me if utsuri is mentioned in the jihada of the Sukehiro school ... This sword was presented in kantei by NBTHK

It's Yasuhiro The sugata and yakidashi pointed to a Shinto blade, but the midare utsuri could lead people to think of a Bizen koto (that's why I hid all the nakago). The point that disqualifies Koto Bizen is the boshi, which should have been in accordance with the hamon as yakidashi is not compulsory. Nidai Sukehiro never produced an utsuri, the shodai did from time to time, but it's a pale bo utsuri that's hard to see, and katana by this smith are extremely rare. Nidai Sukehiro's yakidashi is shorter and the hamon often starts under the ha machi. In any case, bravo to those who dared to take the plunge and found the solution. ps Alex really doesn't know me very well...

I may be wrong, but I don't see how this wakizashi could be a naginata naoshi; I see a simple shobu-zukuri wakizashi with a high shinogi .

I sincerely hope that all will go well for you. Type 2 diabetes? it's reversible, a balanced diet low in fast sugars and exercise is the best solution

Nagasa = 64.8 cm Sori = 0.6 cm Kitae = Standing out ko-itame with a strong ji nie and a midare utsuri. Hamon = Nioideki compact and clear. Boshi = Suguha cho with hakikake along the rather pointed kaeri on the ura side

Whether you agree or not, it's a fact, and the deeper you go into the subject, the harder it gets. I'll skip the rest of your speech, it's a string of words with no real content.

I've held more than thirty swords from this school, so that's a good base. and I never said I was an expert, the real experts are Japanese...

In principle, a kantei is practised without opening a book; it's an exercise in memory. I'll rarely make a mistake with a Rai because it's a school I know particularly well, but I wouldn't say the same about the Nio school, for example, which I know very little about because I've only had the opportunity to study one, which is very, very inadequate.
