Would love to see nakago and definitely boshi on this one. Suspect its shinto but can be a decent piece. Yes, a lot of Tokugawa mon are very late creations, yet it was also one of the most common mons in Edo period. Matsudaira used it and also Tokugawa did send their children for adoption to other Daimyo, and you then see this adopting lineage at times using some manner of Aoi mon as well. There are some arcane methods to determining aoi's age and attribution, like whether the rays are parallel or converging, whether the stems are completely separated as here (which I think tend to be Matsudaira) or not etc.. Hell knows where my book on Aoi versions is though.... but yes this can be a much later creation as well hard to guess without full resolution photo of the mon and makie around it. Makie in most products did change noticably towards the later years of Meiji.

Yep, I would bet on Muromachi Mino. The nakago seems cleaned.

Ugh! I wanted to say right away a Nambokucho Yamato off-shoot Tegai/Mihara type but the hamon is a bit too intricate... Sue Sa?

Agh, I see what you mean. No its not Mishina boshi for certain with the new pictures, I don't remember at the top of my head who specifically changed to sugu-boshi like that - it is unusual I agree.

I don't think it follows the line exactly like that, but yes. Typically - Shinto. One can even try calling it Mishina boshi, but its not too reliable. Just a thought.

Could be real. Hamon seems to be suguha. Can be Yamato Shizu, can be lesser northern name like Kashu Fujishima (small gunome expected) or Uda... With such sugata shinshinto is always a risk, but the work does have this feeling. However there were some people like Kaifu Ujiyoshi who being Yamato trained (Naminohira lineage) did very convincing suguha-Yamato-Soshu in Momoyama times with Nambokucho sugata. P.S. I own Hosho (Hozon) with o-kissaki Nambokucho. They are just even more rare than their tanto.

Well somebody was trying to cook up a ko-bizen kissaki with a fake Ichimonji signature. Also sugata suggests Muromachi period.

Regarding the pedigree, I think its not too encouraging. I've seen dozens of blades owned by US ambassadors, admirals etc., and well, very often those were gifts, and people don't have a tendency of giving gifts equivalent to 100K USD in modern money unless its a bribe. Condition is usually unusually good and fittings are very late but very much upper grade, but I did not see a single blade at the Ichimonji level. I am sure they exist, but these are exceptions. Honestly the most promising provenance would be along the lines "from the estate of a convicted burglar who pulled occupation duty in Nara's shrine park".

Unfortunately I am at a loss re the hammer price is this one. There is a lot of niku in the blade, no strong evidence of midare utsuri, there are no defects... Yes, there are Kamakura blades with no defects - they are TJ as a rule. It is not in polish, but there is very little here suggesting Kamakura attribution.

The greatest issue I have with a modern society is its commitment to morals being a preset of unchangeable postulates. Philosophy worthy of Bronze Age fundamentalists but a wholesome rejection of historical realities. My mother grew up in camps. Cannibalism was rampant. As were very late term abortions. Infanticide. Was this evil? I would not say. Very little in prisons or war qualifies as "good", whichever side one was part of. The problem of modern morals is limited experience our journalists and professors have with life outside their career path. Air conditioning does mellow once's spirit. Makes life a bit more boring also.

I think the most honest statement is - I personally can't see anything in any of these pictures. These are probably good blades. The kitchen counter appears solidly build and well cleaned.

Wow! thanks. I will readily say Yoshikage would be zero chance for me on this one.

That's a first for me. Realizing as noted how much more difficult it is compared to conventional blades. It feels like many things boshi etc. simply do not apply.

I think you might be right here - for some reason I was hasty with Hizen guess, it does look koto. Damn, should not kantei on a smartphone. I would through a bit tangential thought though - Ryokai-Muromachi. But suspect Bizen is the correct answer. unfortunately that is one of the things where I can't distinguish well between Uda, Bizen, Fuyuhiro, Bungo and Ryokai.

Later generation Hizen Tadayoshi?

I don't think there are blades today which are accepted 13th century Enju. Your dealer might be translating sayagaki in a very aggressive manner. With Enju late Kamakura generally refers to Showa+ eras.

On a very personal note I have to wonder if these are Kamakura per se. They both look like earlish Nambokucho.

Its hard to be conclusive with these without seeing details of the work, but: - the mei appears to be the right size, place and strikes, it looks ok. - the blade looks ok for Muromachi. Maybe a bit post-Oei. - the horimono is well cut. Good chance its a real Muromachi Nobukuni. I would send it to NTHK next time it holds shinsa in the US.

Nihonto community is addicted to titles. Often fake ones.

All US museums are patronized by Morihiro Ogawa. He is disliked by many, myself not being an exception.

I think you'll have a blast with these two volumes. Its really interesting to build tables who preferred what, a very different experience compared to Juyo POV we have today. I might have spare copies but I am not sure. Someone with far better Japanese than mine can certainly get much more out of them. As a dumpster diver in Japan I obviously always getting a LOT of hatred from the collegium of American dealers whose dogma is that such activity is impossible in principle. In fact I would characterize it as being hard limited in certain aspects (yes you are buying blades that were seen by dozens of people who know at least something), but very rewarding in others. And one thing you definitely see as having a large impact even today is a mass selloff of Daimyo collections in 1950-1960 which often purposefully severed links to old information. Buying a blade in Japan and finding it is an important Daimyo piece is not only not impossible, but probable, though you have to get used that attribution very often shifts in modern papers downward. If you have Tametsugu suspected of being Daimyo treasure, check the register for Norishige or Go. If there is an important Jubi whose location is unknown today, chances are it was simply sold quietly. A great blade without Jubi status, which was common prewar might even have some generic Yamato papers today.

Probably someone late, shinshinto or later imitating Hosho. Pure masame, high contrast, very uniform like drawn lines and absolutely no ji nie - very late work.

I now see its a light reflection. Anyway it has been considerably shortened.

My take is that if its in good nie, its usually upper grade Soshu. It can be argued that you find it on chokuto etc, but that's too exotic. If its in nioi, you see it being revived by Shimada, and afterwords being used by shinto and shinshinto people.

Thanks! If its absolutely straight, its shinto and there will be one-two possible guys.
