With reference to the replies now moved elsewhere: Guys, this is NOT the place for this, and it sets a really bad precedent. I do not want this sort of thing happening in sales posts, if we allow it then it becomes a free for all. That said, we are here to protect the community and also cannot just ignore it when sellers or buyers have an issue, and they need to hash it out with right of reply and people can make up their own minds. I have a Catch 22 here. Allow it and open the forum for fights on every sale post, or delete it completely and then we are not looking out for the community. So I am going to take the middle ground and continue with the policy of not allowing this sort of thing in sales posts. BUT I am shortly going to split this into a new thread and put it in the Sales/Sellers section, where people can discuss good and bad deals with sellers. I hope everyone understands that is best compromise I can come to right now. Shortly this will be moved, and will formulate a title there where seller/buyer can discuss this and lay out their case.

Hello! I had wanted to add a Kaga tsuba to my collection for a long time, and recently Okan finally convinced me with his wonderful example that was shown here not so long ago. Recently I came across this tsuba. It depicts the classic theme of drying fishing nets, and in my opinion the Kaga inlay is perfectly suited to the delicate nets. Overall, the composition is quite refined. The tsuba itself is made of rich and expensive shakudo, although this is somewhat hidden beneath the dark patina, it is especially noticeable when viewed at an angle. The plate is perfectly polished and shimmers beautifully in the light. I would also note the beautiful sekigane - it was probably mounted on two different swords.

Haynes lists a Meiju as a student of Araki Tomei (H09800) working about 1865-75 and that there is a relationship, or the same person as Inoue Akiyoshi (H00089) The kanji are the same. I have a tsuba signed Akiyoshi which was an early name used by Kiyotoshi (H03368.0, 1804-1876). Not sure if its the same guy. An entry in ‘The Early Famed Works of the Kyoto Smiths (Kyomono no Ko-Meisaku)’, tanslated by Gordon Robson lists a tsuba by Akiyoshi with a shakudo ground. The text states that ‘Akiyoshi is among the skilled kinko of the Aizu during the late Edo priod’ ‘There must be some connection with Kawano Haruaki, and because of his signature and kao, we can agree to such a conjecture.’ There appears to be a similarity between the kao on this tsuba and examples attributed to Kono Haruaki, so it looks like the artisan of this tsuba is probably the one referred to. Akiyoshi seems to have worked around the mid 19thC and changed his name several times Not sure if this helps, or just muddies the picture further. Best regards, John

Hi everyone, I just wanted to share this easy option for displaying your tsuba on your desk. I got these acrylic glass light boxes for about 15 Euro on amazon and I think they make a pretty neat display. I would love to see how you display your tosogu!

I thought you might want a picture of my railroad tassel. Tom

I was talking to Ray Singer about this yesterday. The problem here, as we discussed, is the connection with the Tokugawa. That association is such that few are going to ever say it is a fake, even to this day. Cultural respect, etc. But the fact that sword has no official status -- not Kokuho,Jubi, JuBun or any flavor of Juyo -- is telling. So it appears to be exactly as labeled: a sword signed Sadamune that was owned by powerful member of the Tokugawa family. No more. No less.

Sa blades attributed to specific smiths tend to be highly valued blades. They are considered a big step above the more numerous Sue-Sa and O-Sa Ichimon attributions, and thus are prized. Yoshisada has to his credit 56 recorded blades, including two Jubis, four TokuJus and 42 Juyos. Not too shabby by any standard. That said, top tier work like this is not that common and the setsumei is certainly very positive about the attribution and the quality of the blade. For me, a Sa School lover, I think the price isn't unreasonable at all especially with the current exchange rate for a Juyo work from a good session and great setsumei. And comparing the quality to other Soshu-adjacent schools and smiths, I think they represent probably some the best value in Nanbokucho Soshu works. The value of Sa blades within the Soshu pantheon was something that even Darcy commented on. And while Yoshisada's works are not as well-regarded as some of the other inner Samonji circle such as Yukihiro (my favorite) and Yoshisada's older brother, Yasuyoshi, his work is considered closer to his father's (Samonji) work style than is Yasuyoshi. (Kunihiro mentioned above was also good but was later and not necessarily among O-Sa's inner circle of children and early students.) Yes, there are lots of options at this price range, but if you are looking for a Juyo blade with excellent Soshu pedigree and supreme clarity of the steel and such a wide bright habuchi, I am not sure you are going to find much better at this price. Just my humble opinion. (And FTR, the only reason I didn't jump on it is these days I only collect tanto. My safe and closet are grateful!)

The Toyama Sword Research Society brings together young people and women from all over the country. In recent years, the Toyama Sword Research Association, a sword enthusiast group based in Toyama Prefecture, has seen an increase in its membership among young people and women. Due to the influence of online games such as "Touken Ranbu ONLINE," the number of young people becoming interested in swords is increasing, and the company has made great efforts to make the game more approachable for beginners and to spread the word on social media. This initiative, which is rare nationwide in the world of swords, where middle-aged and elderly men have been the main fan base, has paid off, and the sword is becoming a popular choice for "sword beginners" from a wide range of regions, not just within the prefecture. The Toyama Sword Research Society was formed in 2017 by Yasunori Sawada (57) (Nanto City, civil servant), an enthusiast and former director of the Sword Museum (Tokyo). He holds sword appreciation events about five times a year and visits art museums both within and outside the prefecture. The study group, which began with around 20 members, has now grown to 220, 70% of whom are women. By age group, the most common age group is those in their 30s, followed by those in their 20s and 40s. 40% of people live in the three Hokuriku prefectures, with many in the Kanto, Kansai, and Chukyo regions. Some members are from Hokkaido and Kagoshima prefectures. In order to encourage young people and women to join, the study group has put in place a number of measures to make it easy for beginners to participate. This new sword study group has proven itself to be very successful and is quickly showing the way forward for Japanese Sword Societies in local communities.

When the sword was initially procured and priced, the FX rate ¥/$ was close to 100. So, you were looking at c.$25k back then. Currently the FX rate is closer to 160, which means the $25k would be nearly ¥4m. Furthermore, the Japanese dealers in the last couple of years overcompensated for the yen depreciation somewhat. While previously they used to think purely in yen, as their inflation has been next to 0% for decades, lately they started mentally converting to $ and pricing accordingly, as the sword market internationalised in the last 10-15 years beyond recognition. I remember decent TJ perhaps 8-10 years ago was in the ¥14-15m range, then that became ¥17-18m, now you are looking at ¥20m+. A famous dealer complained to me a few weeks ago about former customers also demanding extremely high prices from him for the swords he had sold to them years ago (but that is a different story for another day…). So, the maths for this sword: You add to the aforesaid ¥4m (the historic price) then the ¥0.75m-¥1m koshirae, the cost of the polish, the fact that the seller probably wants some return to his investment and you get to ¥5m. The sword is rather nice, albeit not my cup of tea. But indeed in the last 15 years the floodgates of information and access have opened, so one naturally has a lot of choice. Just go to Chris’s Nihontowatch website and see what AI has enabled in the last few months. He has put a tonne of valuable (and monetarily rather expensive) information in there - for now for the benefit of people. But such access and info should really be premium….. One important thing: buy what you like and resonates with you emotionally and do not get swayed by people’s likes and dislikes in Sa or Nanbokucho shapes, or more/less nie etc. And measure and weigh carefully options, opinions, facts.

Come to https://www.japanartfair.com/ (No taxes from dealers from Japan, btw) . For this price I would first learn more about Nihonto and second only buy after personal viewing.

Mark, the sword has a mei of Kenryushi Sadaharu. You can see the entry below from Markus Sesko: SADAHARU (貞晴), Keiō (慶応, 1865-1868), Settsu – “Naniwa-jū Mizuguchi Kenryūshi Sadaharu saku” (浪華住 水口剣龍子貞晴作), “Settsu Ikutama ni oite Kenryūshi Sadaharu kore o tsukuru” (於摂津生玉剣龍子 貞晴造之), “Naniwa-jū Kenryūshi Sadaharu saku” (浪花住剣龍子貞晴作), student of Gassan Sadayoshi (月山貞吉), his gō were Kenryūshi (剣龍子) and Kensaishi (剣斎子), we know blades from the Keiō to the Meiji era (明治, 1868-1912), mostly a magnificent sugata with a wide mihaba and an ō-kissaki, dense ko-itame or masame which tends to muji, suguha-hotsure, notare, gunome, he works in the style of his master Sadayoshi, he also added a koku´in seal in the form of the character “chū” (忠・忠) , chū-saku

Keisuke Nakamura gave an interesting treatise on the subject of these 2 blades exhumed from Mitsutomo's tomb. By comparing horimono carving styles with other Sadamune attributed blades and historical oshigata he is a little skeptical and reserves judgement. https://note.com/katana_case_shi/n/ne850e4972025

Yesterday's meeting and update indicated that 78 people have contributed JPY2,430,000 so far, just shy of the 2.5 million yen they are initially aiming for by the end of this month. A plan for the polishing of the Odachi was also handed out, to take place over the first three cold months of 2027 when rust will not be too much a problem. I had a chance to see their Muromachi period blades display, including upstairs a 1499 Katsumitsu/Sadamitsu joint-work naginata that Jussi might recognize. Photos: A B C

Very true, and that only comes after doing the hard yards researching the literature and more importantly experiencing high end swords in hand. Elias, since you are in Germany you should seriously consider attending an NBTHK-EB meeting either in Solingen or Manching. There are many members in Germany who have some magnificent Juyo and up swords, and are only too happy to share their knowledge and collections.

While historical sales are not good indicator of current prices due to several factors of which we have discussed previously at NMB too. You can see Aoi Art had this same sword for sale without koshirae in 2021 for 2,500,000 yen https://web.archive.org/web/20210802211856/https://www.aoijapan.com/katana-mumeiunsigned-attributed-as-sa-yoshisada/ So you can see koshirae has not been historically with the sword. Also new habaki and shirasaya have been made for the sword. To me the workmanship of the blade seems very good but I am not after that in swords. Size and shape of the sword are the factors that would put me off from this purchase. If I would be in position to purchase a Sa school blade some day I would want it to be of the imposing Nanbokuchō shape in which there are plenty of Sa school attributed blades.

Thanks Conway and Bruce. I’ve dug out my copy of Dawsons to refresh my memory on these police sabers. @Ghaad47, according to Dawsons on pages 300-313, your sword with that half-decorated backstrap is a sword for police lieutenants. The police logo on yours looks like what Dawson describes as a 16 ray badge, found on lieutenant and superintendent swords. Whereas a sword with a fully decorated backstrap (similar to the army field grade counterparts), are for police superintendents. These are shown on dawsons page 314-315. *Dawson, Jim.

This seems fairly simple if someone can post a link to the original sale thread. Either the flaws pictured above were clearly stated in the original sales post or they were not….period. This is a contract dispute fellas, either the description of the sword was accurate or it wasn’t, this has NOTHING to do with how anyone “felt”.

With that many sales listings you would hope for a gold membership to support the forum.....

I was told there was an issue but by the time I logged in, all was working fine. The whole of SA has had some serious internet disruptions the past few days. Apparently massive DDOS attacks launched against all the ISP's, and most have had some serious problems, so I'm guessing that was part of it. No-one knows why or by whom, but it's a large one, and taken down most of the providers for a bit. I expect there may be some lingering issues over the next few days.

Yes, probably this is the habaki on the Kanemitsu.

The square inscription that looks like a seal reads 大明成化 (Dai ming sei ka), or, if you use the Chinese pronunciation Da ming cheng hua, alluding to Chinese emperor Chenghua (mid-1400s) It's apparently a motif that was used by Japanese ceramic artisans to give their wares an air of antiquity and authenticity. I think used by Imari porcelain artisans in the late 1800s.

I remember chatting with Markus about this maybe few years ago when it was displayed first time? I can't say about the legitimacy of the item, I just accept it as genuine piece as Tokugawa Art Museum seems to accept it. Now what is interesting about this item that it is maybe not intended as a weapon in my eyes. Markus would be the best one to write his view but I think there could have been some perhaps ritualistic purpose for these extremely wide wakizashi that few shrines have. The historical Masamune (NBTHK demoted it to Tomomitsu) that currently resides at Yasukuni Jinja is another example of these, and there should be few more such wakizashi if I remember correctly. This is of course my personal view but I cannot see any actual advantage in usability when the short swords are extremely wide.

This is the kind of thing that makes me wish I lived in Japan... A famous sword appreciation event co-sponsored by the Toyama Sword Research Association and the branch e-Sword Research Association will be held on the 30th May. At the sword fittings exhibition, you will be able to see the sword fittings that came with the mountings of Satsuki Amee and Atsuto Shiro. This time, the sword lineup is also luxurious, including Bizen Saburo Kunimune, Shindo Go, Masamune, Norishige, Go, Hidari, Kunitsugu Rai, Naotane Daikei, Dewa Daijo Kunimichi, and Kashu Kiyomitsu, and it's already packed to capacity. Getting to hold and examine this calibre of sword is the stuff of legend. No wonder it is already fully subscribed. Sounds like the kind of meetup that Honma writes about in his memoirs. The next one is in July - for those interested and able to get to Toyama.

Jigane is probably very attractive itame. I love Sa hada and it should be a good example of such. The work seems to be very homogeneous, not tired, pristine, without kizu. However, Sa hamon is choji always tends towards ko nie or even nioi. It is a very attractive shade of nioi, but on the blades I really like this is further accented by strong nie activities. Inazuma, patches of nie along the ha, strong chikei. I think this blade is more towards just ko nie. Still very attractive though.

There are many options at this price, if you're prepared to pay that amount it could be a better idea to travel to Japan to inspect some first class swords in hand.

Hi Elias, Welcome to NMB. I'm assuming this is the one AOI has on hold. Nice tachi koshirae if you like blingy mounts. Believed to be a student or son of O-Sa. Not the best of the nidai smiths but still highly rated at jojo-saku. I prefer Sa-Kunihiro. From Sesko's eSwordsmiths. YOSHISADA (吉貞), Jōwa (貞和, 1345-1350), Chikuzen – “Chikushū-jū Yoshisada” (筑州住吉貞), “Yoshisada” (吉貞), “Yoshisada saku” (吉貞作), “Mononobe Yoshisada” (物部吉貞), Sa school, according to tradition the son or student of Ō-Sa (大左), there exists a tantō with a date signature of the Shōhei era (正平, 1346-1370), no tachi are extant by Yoshisada, his tantō have a wide mihaba and some sori, the jigane is an itame-nagare with ji-nie and thick chikei, the hamon is a slightly undulating notare mixed with gunome and sunagashi, the bōshi has a rather long kaeri, we know smaller and larger signatures but it is assumed that they go back to the changes in the active period of a single smith because nothing indicates a 2nd gen., jōjō-saku As to value you have to also factor in the ~20% importation tax so after shipping costs its more like 6mil JPY you'll be paying. I personally would not pay that figure for this blade.

Dear Geraint, Rather than asking for an explanation I couldn't find, I went down the rabbit hole, researched and asked around and did a little write up - all comments are welcome! ------------------------------------------------------- Among the many attribution problems in tosōgu, the distinction between (late) Mino work and the Kozenji school is a challenging one. At first glance the two can appear remarkably similar. Both employ scrolling karakusa, shakudō grounds, gold hirazōgan, floral ornament, and richly decorative surfaces. Both participate in the broader aesthetic world that emerged from the enormous influence of Mino metalwork during the late Muromachi and Momoyama periods. It is therefore that collectors frequently encounter guards which appear unmistakably “Mino,” only to discover that the NBTHK has papered them to Kozenji. Conversely, certain highly refined Owari-style works still receive broad Mino attribution. The reason for this confusion is that Kozenji did not arise in opposition to Mino aesthetics. Rather, Kozenji emerged through the absorption and reinterpretation of Mino decorative language within an Owari context. The distinction between the two schools therefore lies not primarily in motif vocabulary or isolated techniques, but in something much deeper: the philosophy of ornament, the treatment of surface, and the emotional structure of the design itself. To understand the difference properly, we must move beyond the question of what is depicted and instead examine how the surface behaves. The Mino tradition developed in Mino Province during the Muromachi and Momoyama periods and became one of the most influential decorative metalworking traditions in Japan. Mino artists cultivated an aesthetic built around vigorous carving, energetic takabori, rich metallic embellishment, and deeply animated surfaces. Their work often possesses tremendous physical vitality. Ornament in Mino work feels carved into existence through the force of the chisel itself. Even highly refined examples retain a sense of movement and tactile energy. The plate feels worked, excavated, and alive. This sculptural vitality became enormously influential. Mino aesthetics affected not only later Mino generations but also Gotō traditions, Owari kinko, and even aspects of Kaga metalwork. By the early Edo period, Mino visual language had spread widely beyond its original provincial boundaries. The Kozenji school emerged later in Owari, likely during the early Edo period, after Mino artistic influence had already spread westward through political and cultural realignment under Oda Nobunaga and his successors. Kozenji artists inherited many elements of Mino decorative vocabulary: scrolling vines, asymmetrical compositions, gold accents, and soft-metal ornamentation. Yet they transformed these inherited forms according to a different sensibility. Where Mino prized carving vitality, Kozenji increasingly emphasized decorative integration. Where Mino celebrated sculptural movement, Kozenji pursued ornamental coherence and surface harmony. This difference may be summarized very simply: In Mino work, the carving creates the ornament. In Kozenji work, the ornament organizes the surface. That distinction explains an extraordinary number of attribution decisions. In Mino work the eye is drawn first to the carving itself. The relief possesses physical authority. Lines vary with the movement of the chisel, shadows accumulate in compressed recesses, and vegetal forms seem to push outward from the plate. Even when gold or silver decoration is present, these additions generally reinforce the sculptural structure rather than flatten it into surface pattern. The ornament feels organic and energetic. One senses not only design, but physical action. This is particularly evident in Mino karakusa. The vines tend to be deeply cut, asymmetrical, and rhythmically compressed. They twist through the surface with muscular energy. Negative space often feels crowded and pressurized. Around the hitsu-ana and seppadai, the ornament seems to gather force inwardly, creating visual tension and density. The resulting atmosphere is one of Momoyama vitality: forceful, tactile, and animated. Kozenji adopts much of this same vocabulary but alters its function. The karakusa remains recognizably Mino-derived, yet its behavior changes fundamentally. The vines become more evenly distributed, smoother in movement, and more consciously decorative. Rather than appearing as sculptural vegetation carved into the iron, they begin to resemble ornamental patterning spread across a unified surface. The rhythm becomes calmer and more controlled. Space is allowed to breathe. This transformation is central to understanding Kozenji attribution. Kozenji surfaces often possess what might be called a textile sensibility. The entire guard behaves as a coordinated decorative field. Individual motifs no longer dominate through sheer carving energy; instead they participate in an integrated ornamental structure. Hirazōgan becomes especially important in this context. In Mino work, gold inlay usually accents relief carving. In Kozenji, however, flat inlay frequently becomes structurally important to the design itself. Gold highlights distribute visual rhythm across the plate, contributing to balance and ornamental unity rather than simply emphasizing sculptural depth. The emotional atmosphere changes accordingly. Where Mino often feels vigorous and physically charged, Kozenji tends toward refinement, restraint, and composure. One might say that Mino preserves something of the energetic instability of the Momoyama period, whereas Kozenji reflects the cultivated decorative balance of the Edo period. These distinctions become especially important in modern attribution practice, particularly within the NBTHK. In practice, the NBTHK tends to separate Kozenji from late Mino not by isolated motifs but by overall artistic behavior. The central question is often whether the piece fundamentally behaves like a Mino carving object or like an Owari decorative object influenced by Mino. If carving dominates the visual experience—if relief retains sculptural authority and the surface feels physically excavated—the attribution tends to move toward Mino. If, however, the ornament behaves as a coordinated surface system, with controlled spacing, decorative integration, and ornamental calm, the attribution tends to move toward Kozenji. This is why collectors are sometimes surprised by papers. Many collectors naturally classify by subject matter: karakusa, shakudō, gold decoration, and scrolling vines immediately suggest “Mino.” Yet the NBTHK often evaluates according to broader aesthetic logic. Two guards may share almost identical motifs while embodying entirely different surface philosophies. The two example guards illustrate this distinction well: The first guard, papered to Mino, retains strong sculptural vitality. The dense karakusa appears deeply worked into the plate, and the ornament generates considerable visual pressure. The gold mon serve primarily as accents within a carving-dominated structure. The eye responds first to the physical movement of the carving itself. The surface feels excavated and tactile. Even within its refinement, the guard preserves a distinctly Momoyama-derived energy. The second guard, papered to Kozenji, employs similar decorative vocabulary yet behaves very differently. The karakusa is more evenly distributed and rhythmically organized. The hō-ō bird participates in the ornamental field rather than emerging as a dramatically sculptural centerpiece. The entire plate possesses greater decorative unity and calm. Here the eye reads not carving force, but ornamental coordination. The surface feels designed rather than excavated. The lesson is that Kozenji did not reject Mino aesthetics; it refined and reorganized them. The two traditions exist along a continuum rather than within rigidly separate categories. Indeed, the problem becomes even more difficult because late Edo Mino work itself increasingly adopted decorative refinement. As a result, there are many guards that legitimately inhabit a grey zone between late Mino, Kozenji, Kaga-influenced Owari work, and broader Owari kinko traditions. Ultimately, the distinction between Mino and Kozenji is not simply technical. It is philosophical. Mino expresses ornament through carving energy and sculptural vitality. Kozenji expresses ornament through surface integration and decorative order. Both traditions share a common visual ancestry, but they embody fundamentally different ideas about how ornament should inhabit the plate. TL;DR Summary: Mino and Kozenji tsuba can look very similar because both use decorative motifs like karakusa vines, gold inlay, and rich surface ornamentation. However, the key difference is not what is depicted, but how the surface is treated. Mino work is driven by carving energy. The design feels physically excavated, dynamic, and sculptural. Ornament emerges from deep, forceful carving, creating a vivid, almost “alive” surface. Kozenji work reinterprets this vocabulary into a more controlled, decorative system. The surface feels calmer, more unified, and patterned—like an integrated design rather than carved action. In short: Mino = ornament created by carving force and tactile energy Kozenji = ornament arranged as a balanced surface design Because Kozenji absorbed Mino aesthetics rather than rejecting them, many pieces sit in a grey zone, which is why attribution (including NBTHK papers) can be difficult and sometimes surprising.

Sudden resurrection :D Nice T98 with crest. Habaki rising sun pattern. Looks neat. Don't ask for mei it's like 95% fake.

Luke: I agree with Conway that the tanto has likely been mistreated rather than combat damaged. On the issue of historical weight of WW2 objects, some real heartbreaking stories can be read through the Oban Society. This group repatriates yosegaki hinomaru ("writing flags"), which every Japanese soldier carried and were a prized souvenir by allied forces. John C.

Hi Not sure where to put this question so I have added it here. I picked this up in a Car boot sale over the weekend, I did not pay a lot so it is is a rubbish tourist piece I don't mind as I really like the workmanship fantastic piece of carving and I think some age to it also I am not finding much on the net about these so would love some opinions as to age, what the tag might say and are these anyway collectable and any idea of value. Many thanks all Regards Ken

Yep, it is Chinese. Well outside of my knowledge! Looks old but the Chinese are masters of ageing things including ivory.

Only coz your bird’s feet reminded me of it, but here is a Kaga-zōgan kozuka with 5 egrets. Cousins? Congratulations on your tsuba!

The chiseled characters on the tang are imperfect because of wear and tear. But I think that the second kanji looks like 継 (tsugu). The name may be 義継 – Yoshitsugu. FYI: yoshtsug.jpg (91×250)

Thank you very much for all the information and insights you shared with me. I’m genuinely grateful for it, especially because I’m still very much a beginner and have only started learning about Japanese swords relatively recently. The more I read comments from experienced collectors, the more I realize how large the gap is between beginners and people who have studied Nihonto for many years. You notice details, ask questions, and consider aspects that honestly would never even come to my mind to research or evaluate on my own. That is exactly why comments like yours are more than helpful to me — they help me avoid mistakes and learn how knowledgeable collectors actually assess swords beyond first impressions, papers, or historical age. So I truly appreciate your time and willingness to share your experience. Thank you again — your advice has been very valuable to me.

That article is misleading. The first pic appears to be a fake too. The hada you'll see on unpolished swords or ones not fully professionally polished looks nothing like that. In fact, it's barely visible in most cases. And looks nothing like layering. The closest you'll find is visible hada like on Gassan ayasugi hada etc, but in most cases it will appear more like this... There are high end sword oils recommended, but for the average sword that is found out of polish and has been cleaned with Isopropyl, a few drops of any decent gun oil will work to prevent rust. Don't pour oil on the blade or leave a thick layer. A quicj spray or a few drops onto a clean soft tissue, and then wiped over the blade in one direction will leave enough film. If you can see pooling or droplets, you have used too much.

This is a translation of the setsumei giving the opinion of the shinsa panel. Worth reading carefully. 65th Jūyō Tōken Designation Summary Designated on November 7, Reiwa 1 (2019) Classification & Attestation Item: Katana (刀) — One blade (一口) Signature: Mumei, attributed to Sa Yoshisada (無銘 左吉貞) Submitter: Paul Martin (ポール マーティン) Measurements (Sugata) Blade Length (Nagasa): 66.7 cm (2 shaku, 2 sun, 0 bu) Curvature (Sori): 1.6 cm Motohaba (Base Width): 2.8 cm Sakihaba (Tip Width): 1.8 cm Kissaki Length: 2.9 cm Nakago Length: 18.5 cm Nakago Sori: 0.1 cm Appraisal & Technical Description Shape (Taihai) Shinogi-zukuri with an iori-mune. The blade exhibits standard width proportions with a typical differential between the base and tip width. The curvature is shallow, culminating in a slightly elongated chū-kissaki profile. Forging Pattern (Kitae) An itame-hada foundation seamlessly intermingles with areas of mokume-hada. The grain characteristically flows (nagare-gokoro) toward the cutting edge. The entire steel matrix is densely packed with fine ji-nie, displaying an excellent jigane clarity that yields a faint, soft utsuri (reflection). Temper Line (Hamon) A masterfully restrained ko-notare(small wave) serves as the primary motif, interspersed with ko-gunome(small undulating steps). The overall temper is intentionally low-profile, exhibiting active ashi (legs). The steel displays brilliant metallurgical activity near the cutting boundary, where yubashiri (drifting mist formations) fuse with sunagashi (streaks of sand). The nioiguchi remains bright, crisp, and exceedingly clear. Tip Temper (Bōshi) The temper line runs true (sugu) into the point, executing a shallow, rounded turnback (komaru-gokoro). The apex of the curve terminates with a delicate, swept hakikake (brushed) texture. Engravings (Horimono) A classic bōhi (wide groove) is cleanly carved into both faces of the blade, running entirely through the tang. Tang (Nakago) Ō-suriage (significantly shortened). The heel profile is finished in kirijiri (flat cut) with indistinct, faint yasurime (file marks). The tang features two mekugi-ana (retaining pin holes) and remains strictly unsigned (mumei). Official Commentary & Historical Context Yoshisada was an elite bladesmith belonging to the Sa lineage of Chikuzen province. Historical scholarship positions him alternately as the direct son or primary student of the legendary founding master, Sa (Samonji). His production era can be confidently contextualized through existing dated examples, notably a signed companion piece from the 13th year of the Shōhei era (1358). While signed long swords (tachi) by Yoshisada are vanishingly rare, his signature is primarily preserved on short daggers (tantō) and sidearms (wakizashi). His styling on long blades typically trends toward a highly controlled, narrower hamon footprint compared to his peers. This specific mumei katana perfectly captures those defining school traits. The blade's overall width is classical, paired with a sophisticated, gentle curvature. The hamon centers around a subtle, low-profile wave pattern. While the upper and lower halves show variation, the upper section resolves into a quiet, uniform temper line. Enhanced by vibrant nie activity, a flawless jigane, and remarkable health from tip to tang, this piece stands as a premier, highly dignified exemplar of the Sa Yoshisada tradition.

I was thinking tokusa! Dried and used to polish shirasaya?

https://www.bonhams.com/auction/32178/arts-of-the-samurai/?page=2 This is taking place this month, 51 swords, some tsuba. Does anyone know whose collection this is/was?

All, this is my sword. Everything stated on all of the 3 forums it has been posted on, including this one several months ago, was true and honest. I am taking this to have Chris look at it in hand tomorrow and hope to find out a little more about it. I do not collect swords but bought this sword from the son of the WWII AAA vet that brought it back. Actually, the sword was sort of a "throw in" and I probably would not have purchased it (I really know NOTHING about swords like this) if it hadn't been for the Type 2 Arasaka para rifle that was with the sword as the bring backs of the vet. I didn't want to see these broken up since they have been together since he returned home after the war. It was a package deal (rifle and sword) and I know much more about the rifle than the sword and what I gave I knew I wasn't losing anything on the deal so I kept both together. Once I had the sword in hand and showed it to another local US military collector he told me that from what he could tell (a novice sword guy) that the blade was very well made, clean with no damage, and could be very old so I decided to try and get a little more information on it. I hope that I can get you a few more pictures after tomorrow and have ChrisW comment his much more informed/experienced thoughts on this sword. I did post it on here but know that sometimes a more well known member of a forum may get more responses than someone who just "pops up" out of no where asking for help. I hope you all now have a clearer picture of my goals, and appreciate Jeff posting it back up on the board for me. I am primarily a US military collector with a focus on WWII, which is how I even came to own these items. Hope to give all more info this weekend after Chris has this in his hands for thoughts and inspection. Brian
