I went to the Tokyo National Museum to see the O-Kanehira what they say one of the best Japanese sword.

I have seen it several times in the window.
I don't know who polished it, but the polishing work is not good, or horrible. Even if it is called an excellent polishing as "Art sword". It brings up the layer pattern so much, that the utsuri is masked by the visible layer.

On the other hand, the habaki is excellent. It is very original, made of un-refined copper. The surface is just a remains of filing work. It must be made at the same time when the blade was forged out. It shows that the blade was a simple weapon when it was made. Simple weapon is beautiful, while art sword is ugly. This is the key of the beauty of Japanese sword.

An interesting sword made of old iron from the "Kawagoe castle"

I have found an interesting sword made by "3rd Naohiro". The inscription on the tang says that this is made of old iron from the "Kawagoe castle". The steel has very visible layer pattern, hamon is made of large particles including much kinsuji around it. The blade looks like a Shoshu style, and different from his usual work. His usual work is more compact steel, and hamon also is made of small particles (ko-nie) or smallest particles (nioi), that looks like a Bizen style. Probably the difference is caused from the material.

The owner explained that he got some big nails from Kawagoe castle restoration around 1970. Then he brought the steel to the smith and ordered this sword. 3rd Naohiro told him that he mixed the Kawagoe sleel within the blade steel.

Studying the Yoshiie blade carefully, I found that the core steel appears in the shinogiji. It must be Kobuse or Makuri steel construction.
In the rough sketch, the steel near the back in shinogiji is core steel.

I went to the Chido Museum to see some swords on exhibition. I will introduce two masterpieces in that.
1) Tachi "Nobufusa" - The shape is formed with big fumbari, koshi-sori, and small kissaki. The steel layer pattern is looking uneven. A large layer pattern steel and compact layer steel are irregularly appeared. But the steel quality is very good. The hamon is mainly large particles (nie), making komidare and ko-choji pattern. The character meets the requirements to see it in Ko-Bizen group.
A wide utsuri appears along the hamon, following with a clear jifu between the utsuri and hamon. Additionally, midare utsuri pattern appears in that wide utsuri. The appearance is fantastic.
Another excellent point of this blade is its kissaki. It is very small like most of other blades in Ko-Bizen group. But this kissaki has very enough width of hamon. I am not sure if this is just an original style or worn. Anyway, such a small kissaki with wide hamon is rare and interesting.

2) Tachi "Sanemitsu" - Some people say it is Osafune school. The shape looks robust with big fumbari, while the kissaki is a little worn. The hamon is ko-choji made of small particles and large particles(ko-nie and nie).
The most impressed point of the blade is its utsuri. It starts as straight pattern following with clear jifu between the utsuri and hamon. Then it becomes a midare pattern utsuri. The midare utsuri doesn't followed with clear jifu, but it is very strongly appears as irregular denseness of steel particles (jinie). That appearance of steel is very beautiful. It is not only beautiful for eye, but it shows the mysterious activities of sensitive steel as well.

I introduce a sword that I saw at the Kasuga-taisha shrine in Nara.

It is originally unsigned. It is unbelievably healthy blade from 12th century. It has been kept in the shrine as untouchable treasures since it was dedicated in 12th century, and recently it is re-polished. The blade has full meat on bevel. The steel is bright and clear. The hamon particles are very bright and dense, making komidare and choji patterns in straight outline. It is amazing that the hardened area is full of particles. It looks hard and dense, and including full of cutting power. The hamon in kissaki is very wide almost full of kissaki area. The appearances of this blade is quite different to other blades in that age what we often see at museum and sword clubs. Most of those blades are very worn.
The person who study old blades in 12th century, like Kobizen, should come to the shrine and study this blade to see how the blade is robust when it was made.
(=> Kasuga-taisha shrine)
Unfortunately, the polishing is the modern style, and its cheap hadori work breaks the elegance of the blade.
(for information => Why originally no signature on good quality blade?)

I went to the exhibition "MEIBUTSU-Treasured Japanese Swords-" at the Sano Museum. There were many good swords in the window. Especially, I was very impressed with three Ko-bizen blades displayed side by side. Those were two Naritaka and one Tomonari.
Ko-Bizen is not a name of one individual school. Its literally meaning is "old Bizen". Before the early 13th century, there were not appearing the particular schools like Ichinonji or Osafune. So we classify such old Bizen blades with the word "Ko-Bizen". Probably there were several small schools in that age. Therefore, Ko-Bizen blades includes various characters.
The three Ko-Bizen blades in the exhibition were all masterpieces, and interesting to study each of them.
1 Naritaka

2 Naritaka

3 Tomonari of Itsukushima shrine

The first Naritaka had a small kissaki and its hamon was ko-midare and ko-choji including many complex appearance.
The next Naritaka was very healthy. Its kissaki was not so small as the first Naritaka. The shape was very powerful. The hamon was suguha outline and many choji-ashi. The hamon particles were dense konie.
The Tomonari was very famous as "Tomonari of Itsukushima shrine". It was also very healthy. The shape was powerful and the hamon was suguha outline with many choji ashi made of dense konie. It looked almost just made out, except for the kissaki shape that seemed a little worn. Its character was very different to other Tomonari like Uguisumaru or Tomonari of baronYamamoto.
When I studied those three blades in the window, I thought that the characters we have learned as Ko-bizen blades were characters of worn out Ko-Bizen blades. The healthy Ko-Bizen blades were very powerful in its shape and steady in its hamon.
I believe that the Ko-Bizen blades were made as simple weapon, and never have tricky appearances. That is the reason why they are so beautiful.

One dealer came to our shop bringing a tanto that he found at some old family's residence.

It is "Rai Kunimitsu" with shirasaya. It has an old registration card published by the Occupation Army just after WWII. The habaki is solid gold, double pieces with a base. The character of the blade looks just like Rai Kunimitsu as its shape, steel, hamon and engravings.
The tang never smelled like a fakes as to the rust condition nor the shape. But the chisel work of the signature does not look like Kunimitsu's. It looks like Rai Kunitsugu's work rather than Kunimitsu's.

It is very interesting that if Kunitsugu made a signature for his elder brother Kunimitsu. We already know that Kunimitsu and Kunitsugu made signatures for their father, Rai Kunitoshi. Such supporting is common in some schools.
But I am not sure between Rai Kunimitsu and Kunitsugu.
We could not get solution about this mysterious tanto in such short time as one evening so I let it go with the dealer.

I went to the exhibition "Bizen swords" in the Seikado museum.
There were Kobizen, Ichimonji, Osafune and other schools in Bizen province. All of them were masterpieces.
I started studying from Kobizen to Ichimonji, Osafune ...
Of course Osafune blades are masterpieces themselves. But in the line-up of the room, Osafune were not as interesting as comparing Kobizen or Ichimonji.
We had to be deeply impressed that Kobizen and Ichimonji are the best blades in sword history.
Especially, Masatsune, Tsunemitsu, Takatsuna, and Yukimitsu in the Kobizen school were excellent masterpieces.

Some days ago I saw one good blade at a kantei club.
I have met the blade twice in the past. The first contact was about 10 years ago.
Every time it has brought me a fresh impression.

The blade has no signature by shortening, and is attributed to the "Awataguchi" school.
But the attribution does not matter because the blade is very good. It doesn't have any title or papers.
The shape of it means 13th century.
Regarding the steel, a little large layer pattern is covered with full of jinie, and utsuri appears with quite clear jifu.
The hamon is made of bright nie, and it makes a mild lined kochoji and komidare pattern.

The blade brings a natural and powerful feeling.
Every aesthetic blade have to be ashamed of itself in front of this blade.
I have understood that "Good blade is an instrument to build your personality up".
We can voyage into the infinite world that has only 3cm height from earth to heaven.
This blade is a good example of the words by General Yamaoka who was a leader of the Japanese sword culture before WW2.
"Beauty comes on naturally without wanting it, skilfulness comes on automatically without designing it."
