Looking for a solid iron tessen, i.e. non folding. I know they are pretty obscure and don’t pop up too often, but figured there might me some lurking out there. Only stipulation is that it needs to be in the US since I refuse to participate in this tariff nonsense. 
 

Thanks

I know Raymond Yan had a folding one for sale recently. Might be worth shooting him a message to see if he has a line on any.

There are also some schools where a specific type of shinae - shinae-ware, or small crack-like openings in the horizontal grain - are expected and not considered a flaw at all. In particular, the Hosho school's masame-hada has a tendency to produce these and it's even considered a kantei point for that school.

My understanding was that shinae and shinae-ware run perpendicular to the blade, whereas the kitae-ware one sees in Hosho run with the masame (as openings in the grain), so parallel to the blade. 

Markus Sesko defines as follows:

"shinae (しなえ) – Cracks or wrinkles running crosswise through
the ji. Can be caused by poor steel including much of slag or a rough
forging. See also mukade-shinae (百足しなえ)."

Hi Nathaniel,

 

Why? As a member (since 2007) of the NBTHK via the American Branch. The American Branch of the NBTHK current have some Canadian members and one adviser. I enjoy my membership and have gotten many free reference books via the NBTHK American Branch over the years. Here is a link (see below) their website for more information and all communication is in English. Not sure if they use spam filters on their email but I know many members there for many years so I can help you contact them.    

 

NBTHK - American Branch    

Many thanks David, seems like that might certainly be the easiest way to proceed.

Well that may well make things much easier! Thank you Thomas. 

I tried emailing in late November, January, and last week. Will switch up the address and see if that helps! Many thanks Lewis. 

While not related to the kinzogan itself (though to my eye it appears done by the same person), does the sayagaki look off to anyone else? 

Hi all, 

I'm looking to sign up for an overseas membership with the NBTHK (honbu), and the information on the website seems to indicate to email them at nbthk.member@touken.or.jp 

I've sent a few emails (in a mix of English and Japanese) but received no response. I don't see any other form or link to register online. Am I missing something here? 

Any pointers or recommendations would be much appreciated! 

While I (unsurprisingly) have no insights to share, I for one would love to see more pictures of the rest of the sword if you're willing to share!

Very interesting topic, nicely explained. Do the ‘official appraisers’ have to undertake blind identification of already authenticated swords as part of their training and in ‘continuing professional development’ as medical/science people etc are required? 

 

A few years ago, a group of influential wine connoisseurs were asked, under strict conditions, to taste the previous year’s top ten wines including the bronze, silver and gold medal winners and place them in order. Their efforts were no better than random rankings and they especially couldn’t identify the gold medal winner 😆 No doubt that was due to particularly high solar activity or a ‘skeptic present in the room’ during the tasting! 

While I haven't seen this "study" you're referencing, I'm not sure your conclusions follow or derision makes any sense, at least from your description of it. Do you have a link or source setting out the methodology?

More generally, any list of top wines is one person or panel's subjective opinions, and one wouldn't expect a different person or panel to reproduce it. It's not some list with objectively gradiating features that distinguish one from the other in terms of "quality" when clearly they are all good wines. This is why people into wine read reviews and rankings lists written by multiple people and learn to understand the tastes and preferences of the reviewers and how they match up with their own. The question I would have thought more pertinent would be whether the experts (who I'll assume were sommeliers, not just connoisseurs) could identify the wines, not order them based on the results of someone else's rankings.  This isn't to say there isn't plenty of bunk in the wine world, but I'm not sure whatever it is you've identified here counts for much. 

Regardless, back to swords, and while I certainly can't speak to any requirements of assessors, nyusatsu kantei is very much a thing and one would imagine something they participate in regularly. It might be worth your checking out the regular kantei problems posted by the NBTHK (latest here: https://www.touken.or.jp/english/nbthk/swordjournal_December.html) and referencing some of the usual books on the process. 

Useful article here from Markus Sesko on Tensho vs Keicho suriage:

https://markussesko.com/2018/04/25/tensho-suriage-and-keicho-suriage/

Very interesting, first as I've been pining after a Nobutaka wakizashi in Eirakudo (https://eirakudo.shop/601981), but also as it reminds me of one of the recent NBTHK kantei problems available on their website. 

I again thought Nanbokucho Mino and in my head guessed Naoe, whereas the correct answer was Horikawa Kunihiro. While I don't know that I can do a translation any justice, the initial discussion on the sugata points to viable options as Nanbokucho, Keicho Shinto (and very late Muromachi), and Shinshinto. It then goes on to discuss why the first and last options didn't fit the bill.

"The NBTHK hozon paper identifies it as Kai Mihara, while the Kurashiki Museum paper attributes it to the second-generation Nanki Shigekuni"

 

NBTHK attributed it to Kai Mihara

 

I would disregard the Kurashiki papers

Just for example on that point, you have this on Touken Komachi as well (quite a nice sword to my eye, but with a few knocks against being likely shinshinto suriage and mumei):

https://www.toukenkomachi.com/index_ja_tachi&katanaA021125.html

Kurashiki papers to a jojo-saku ranked smith, and then four months later NBTHK papers Hozon to...Takada. Not to knock Takada (I have a lot of interest in the school) but that seems like a pretty significant downgrade. 

Thanks for this Jussi. 

Just in terms of showing my thought process (primarily so that my beginner mistakes can be highlighted for me) to my eye Nanbokucho sugata, with the size and o-suriage pointing to that period rather than a retro throwback from a later period. Masame/nagare in the shinogi-ji pointing to Mino-den, and togari elements in the hamon agreeing with that.

Guess is Naoe Shizu (maybe Kanetomo or Kanenobu?).

I returned it. But now I have a little over $2000-2400 to spend on, preferably, a papered Muromachi Wakizashi. Any suggestions?

I may have something that fits the bill that I'm debating parting with. Am tied up for the next few days but want to shoot me a PM? Hozon, late Muromachi, shobu zukuri. 

Otherwise there are a few good options (at least to my beginner mind) in the for sale section here on NMB. Would also recommend checking out Touken Komachi as Tsukada-san is great to work with and she has quite a few reasonably priced offerings: 

https://www.toukenkomachi.com/index_en_tachi&katana.html

Is the mei signed over top of the patina/corrosion on the nakago? 

For reference, some of the security features of the Hozon and Tokubetsu Hozon papers are discussed here:

My apologies for the quote Rohan, but I can't get the spoiler box to work on my phone. Have edited the contents of the spoiler box (so its content is mine, not Rohan's), though conveniently I agree with Rohan's order.

Hello,

If the sword is TH Kongobeï Moritaka saku, you should have the generation on the paper ?

This will give you a time scale.

 

My feeling is that it is 3 fingers maki okuri (originaly 4 fingers over the 2nd makugi ana). You can see a deep change in patina color betwen the two mekugi ana.

 

Best,

Eric

My understanding was that the NBTHK only specifies generations in rather rare cases (or I suppose better put, typically does not specify generation). Am I incorrect in this, or is there a peculiar exception for this school?

I had kind of written this one off a bit because of the price, but have a sword signed only Bishu Osafune Sukesada, but it is one of my favorite pieces in the collection and is overall one of the most interesting and beautiful Bizen pieces I've held, largely due to the (imo) insanely beautiful sashikomi polish on it. It is like the sun behind clouds.

Now that is quite the stunning piece. Not to sidetrack from the original topic too much, but would you mind posting the measurements of the Sukesada? 

Very interested to see what the more experienced members think, but just on their face they seem quite different pieces, while both gorgeous. A large and wide Enbun-Joji sugata Yamato style katana vs a rather elegant katateuchi-seeming Bizen blade (at least to my beginner eye, given its short length, narrow width, and shorter nakago). I like them both, but would enjoy hearing what draws you to each of them.

Phenomenal, thank you very much! That is extremely helpful and greatly appreciated. 

Hi Michael,

Yes, it should be Hoki Province with work in the Shinshinto period (Ansei era ish), and one of the smith's names was indeed Shimizu Yoshiyuki (apparently after being adopted by another swordsmith it seems). I think you have found him there.

I believe there is one of his bokuto featured in Paul Martin's latest book, but will double check when I get home. There also a few fittings that the NBTHK have certified as having been made by the man himself (including at last one set of menuki). 

... 

Just to close this particular loop, on pages 154-56 of Paul Martin's Japanese Swords and Armor, the author has included photos of several pieces of tosogu attributed to Miyamoto Musashi, as well as a bokuto attributed to him.

With respect to the bokuto, Mr. Martin states the bokuto "was made by Miyamoto Musashi at the request of the lord of Matsui Castle, Matsui Yoriyuki. He asked Musashi to make a bokutō...to the same dimensions as he had used in his last duel on Ganryujima. The bokutō is of faulty standard dimensions ensuring its ease of use, just in an extended length ." (italics omitted)

With a bit of twister I got further shots. The Yasumitsu wakizashi was turned away and almost buried in the display cloth, so I could get no clear shots of it.

 

Thanks so much for the photos. I can't quite tell from the photo, but was the boshi on the Kiyomitsu ichimai? Looks like it flares out at the yokote, but I can't quite tell if I see a maru and kaeri or if it's just all hardened.

Hi Nathanial,

 

I have a feeling that those stats were taken from a series of ukiyoe wood block prints which featured details of each of the 47. As this medium was catering to the kabuki crowd, it's not beyond the realms of possibility that they hyped up the dimensions to ridiculous 'superhero' lengths.

Many thanks for the thoughts there Dee! Just caught my eye as aside from some of the shinshinto kinnoto, I don't know that I've seen many measurements of quite those lengths for more standard shinto katana (not that they didn't exist I'm sure, and assuming the ronin weren't carrying long ubu koto tachi).
