Kubo's Pens

Kubo Kohei stands nowadays as the sole maker of nibs in Japan not associated with a pen maker. And this in itself is an interesting fact that deserves a separate reflection. But today I want to speak about some of the operations in which nibmeister Kubo has participated.

As of today, other that the nibs one could order directly from him, it is possible to find Kubo nibs on pens Tohma, made by Toma Kiyotaka of Pen Cluster, and on some models by Iwase Seisakusho, albeit its activity seems currently suspended.


A Model N by Iwase Seisakusho with a nib by nibmeister Kubo.

But nibmeister Kubo has a long history in the pen industry in Japan. Two brands associated with Kubo were Nobel –or Nobel's, as he likes to call it-- and Elliott.

The Elliott company was founded by former worker of SSS Uesugi Yoshizaku around 1936 or 1937 in the Kita Ward in Tokyo. Around 1960, Kubo's uncle bought the company and Kubo Kohei started working on it. The engagement with this brand lasted until around 1980.

On top, a pre-Kubo Elliott pen from 1950s. Bottom, an Elliott pen that looks like a Nobel pen.

In parallel, at least during the late 1960s and 1970s, Kubo Kohei also worked on his own brand Nobel. For those pens, he used injected plastic for the bodies and adopted Platinum cartridges and converters as filling mechanisms, as was the common practice among small companies of the moment.


Two Nobel pens: the "Super Gold" model on top; and a pocket pen. Both were made by Kubo Kohei. They use Platinum cartridges.

So these are some of the nibs and pens made by nibmeister Kubo. However, they are not easy to find in the market.


My thanks to Mr. Kanesaki, Mr. Sugimonto and Mr. Sunami.

Note (Sept 1st, 2019): I have changed some of the original pics form some others with better quality.

On Iwase Seisakusho

I have mentioned Mr. Iwase several times (::1::, ::2::) on these Chronicles—he is a pen aficionado who decided to master the craft of raden decoration.

Mr. Iwase started his training about 15 years ago. At first, he customized pens, mostly Montblanc and Pelikan, that he sold locally in Tokyo. His trade soon included some pen bodies made by lathe master Momose Yasuaki equipped with nibs by nibmeister Kubo Kohei.

In 2018, Mr. Iwase decided to become more serious and systematic on his hobby. He created the brand Iwase Seisakusho and started signing his creations. And the selling channels were Instagram and some pen shows.

The pens under the brand could be categorized in three types: customizations, a regular model, and a small number of special pens.

The customizations were made on Montablanc and Pelikan pens. Mr. Iwase applied his craft on their surface and left the operative part of the pen untouched.


A Montblanc 149 customized by Mr. Iwase.


Three customizations over Pelikan M1000.

The regular model, model N, was made over unused bodies manufactured by Ishi Shoten (owner of the brand Yotsubishi). These bodies hand to be adjusted, completed with the filling system –Japanese eyedropper-- and nib and feed sourced by nibmiester Kubo. Needless to say, the pen was decorated by Mr. Iwase with urushi and raden.


The N model by Iwase Seisakusho.

Finally, the special models –called generically Kinsei pens-- were one-of-a-kind units. The pen bodies were the work of lathe master Momose; the nibs, were, once again, the product of nibmeister Kubo.


Two examples of Kinsei pens by Iwase Seisakusho.

The problem of this operation was the very limited production that, to make matter worse, relied solely on the hands of Mr. Iwase. And as of today, July 2019, the production is stopped and the communication channels are disabled.

Iwase Seisakusho, therefore, was alive for about a year with a total production of about 30 pens.

Too few pens, and too short life.

These pens were interesting for both the decoration and the features as pens, particularly in the case of the N model and the Kinsei pens. Japanese eyedroppers with interesting nibs and ebonite feeds... And a gorgeous and well made decoration.


Interesting nib, interesting feed.

Too good to be true? Too costly? Too expensive?

Or just too much for a very small operation?


My thanks to Mr. Iwase.

The Kubo Singularity

The big three Japanese pen companies make their own nibs, and it seems very hard to get those nibs as spare parts or as third party nibs for other makers. However, there are cases of that:

Hakase uses Pilot and Sailor nibs with their own original imprint. Ohashido and Taccia do the same with Sailor nibs.


A Pilot nib labeled as Hakase.

The rest either use Pilot nibs without any modification –StyloArt Karuizawa— or use some of the traditional supplies of third party nibs: Bock for Eboya and Masahiro (although previously Masahiro implemented Pilot nibs); JoWo for Taccia (lower end pens) and Wajimaya Zen-ni.


A JoWo nib labeled as Taccia.

The newcomer Iwase Seisakusho aims at sourcing its nibs from old nibmeister Kubo Kohei for its original pens. However, this is still an uncertain operation whose continuity we can only speculate about. Not to mention that the old age of Kubo Kohei –pushing 90 years old-- might affect any plan for a long term supply of parts.



Nibmeister Kubo at work.

But the bottom line is that Kubo Kohei is the sole independent maker of nibs in Japan, and his production is small, slow and artisanal.

Is there room –and market— for another independent operation in Japan to supply nibs and feeds to small pen companies?

Anonymous Music

My latest acquisition is an anonymous pen with a very non-anonymous nib. And this combination make the whole pen all the more intriguing, and, for some, appealing.

The pen, in essence, is a Japanese eyedropper, made of ebonite with a very discreet maki-e decoration –a "tanzaku" (poem cards) pattern. The clip is of the teardrop shape, just like many Ban-ei pens.


An anonymous pen. Other than the inscriptions on the nib, the only text on it says R14K, and is on the cap ring. The very discreet maki-e --a "tanzaku" pattern-- is not signed.

And this clip, together with the overall shape of the pen and the shape of the section, and even the geometry of the ebonite feed point out at Ban-ei (Sakai Eisuke) as the master mind behind it. However, this idea is nothing but a guess, although this pen is very likely to have been made in the 1960s at Asakusa area in Tokyo.


A Ban-ei pen (top) and the anonymous pen with an interesting nib. Note the similarities in the shape. The Ban-ei pen is larger in all dimensions.


Feeds and sections of the pens on the previous picture: Ban-ei on top, anonymous on bottom. This geometry of the feed was very common in Japan from the 1960s till well into the 1990s on smaller pen makers.

The comes the nib—a beautiful music nib perfectly identifiable as made by nibmeister Kubo Kohei. In fact, the nib inscription NK stands for Nobel Kubo, where Nobel is one of the brands Mr. Kubo created during his career as nib maker. The nib is likely to be a replaced unit, but it could also show the origin of the pen itself. Then, is this a Nobel pen? Many a Nobel pen were anonymous –no brand name was imprinted on the pen--, but ebonite was not a typical material on that brand as Mr. Kubo doesn’t work with the lathe.


The music nib by Kubo Kohei. It is made of steel and is gold plated. The inscriptions read " STANDARD / NK / (JIS mark) / IRIDIUM / < 3 > / NPK ".

All in all, not much we know for certain about this pen, but the nib, and the unpretentious decoration make it most interesting.

These are the dimensions of the pen:

Length closed: 138 mm
Length open: 119 mm
Length posted: 166 mm
Diameter: 13.7 mm
Weight: 16.7 g (dry)
Ink deposit: 2.3 ml

And the search for information continues…

Kubo, Yotsubishi and Iwase

NOTE added on July 23rd, 2018. The body of this pen is not a creation of Mr. Momose, but an old and unused stock of pen bodies of Ishi Shoten's Yotsubishi.


The works of Mr. Iwase as a raden artist have already appeared on these Chronicles, and today I wanted to describe more in detail one of his creations.

Two are the basic types of canvases Mr. Iwase uses for his works—Pelikan and Montblanc pens on one side, and pens manufactured by old lathe masters and companies long gone lathe master Momose Yasuaki. Today’s pen belongs to the later type.

Three elements characterize this pen: the pen body, the nib, and the decoration. Each of them was created by a different craftsman.


"18 K pen raden / Kubo Kohei fountain pen".

On this case, the basic pen was made by the company Ishi Shoten for its brand Yotsubishi. Its material is ebonite, although the barrel and cap finials are made of wood. The pen was originally intended as a Japanese eyedropper –the tail can be unscrewed and detached from the barrel--, but the final result is a cartridge-converter pen (Sheaffer type). The cap lip is protected with a silver ring.


A raden pen...


... or a cartridge/converter pen.

The nib and the feed were provided by nibmeister Kubo. The nib is made of 18 carat gold and is associated to an ebonite feed. The size of the nib would be comparable to a Bock's #5, or to a Pilot’s 10 (::1::, ::2::) or a Sailor’s “big” size, although the feed's diameter is bigger: 6.5 mm.


The Kubo Kohei's nib: "ELEGANT / KB / 18K 750 / MADE IN / JAPAN".
The feed has three ink channels that provide a rich ink flow.


Writing sample with the Kubo-Yotsubishi-Iwase pen.


Nothing special on the tip. Just well cut.

Finally, the decoration is a rich example of the raden technique: carefully cut sea shells glued to the pen body; then, urushi is used to fill up the spaces between the shell stripes and smooth the whole pen. Ad additional later of transparent resin protects the decoration. The gripping section is decorated with red urushi.


There is a simple inscription the cap ring: "silver 925 / 11/20".

All in all, the pen is an original and attractive work; the final result of two Japanese craftsmen working on old forgotten batches. And in this regard, this is not a unique example, albeit other models are mostly one of a kind.

This pen is one of the 20 units Mr Iwase marketed in 2015 and 2016, some of which were sold through the Wagner group. And as it is often the case on artisanal products in Japan, there is no clear sign of the authorship, with the sole exception of the engraving on the nib. However, not many stylophiles (much less occasional buyers) would identify the letters KB as a signature of Mr. Kubo.

These are the dimensions of this pen:

Length closed: 142 mm
Length open: 126 mm
Length posted: 165 mm
Diameter: 15 mm
Weight (dry) 21.9 g
Ink deposit: 1.1 ml (Sheaffer converter)

Kubo Meets Sakai

The figure of Kubo Kohei (久保幸平) is already known to the readers. He is a very prestigious nibmeister with a long history of nibs made for his own brands –Elliott, Nobel–, and for others –Push, Danitrio, even Zôhiko. The purpose of this Chronicle is to show some more remarkable creations of this master.


An unusual music nib by Kubo Kohei.

Kubo Kohei has made music nibs in the past, as I have reported here. However, that example was a very traditional music nib: two slits, three tines. The following examples go one step forward: three slits, four tines. The result is a very broad and wet line showing a good –but not extreme— variation on the writing.


Writing sample of a 4-tine music nib by nibmeister Kubo.

These three music nibs are associated to three outstanding pens—three old pens made by Sakai Eisuke (酒井栄助). They had not reached the market and had been retrofitted with Henckel nibs, which is not rare in what looks like production leftovers by the Ban-ei group.


All three nibs carry the same inscription: "ELEGANT / KB / 18 K - 750 / MADE IN / JAPAN".


However, the ways their tips are cut are different--the one on top is very sharp, and that on bottom is the roundest of them.

These pens are all Japanese eyedroppers of very generous dimensions. So big, in fact, that the Kubo’s nibs seem a tad too small. These are the dimensions of the pens:

-.Wooden.-

-.Plain,
- black ebonite.-
-.Bamboo-like,
- black ebonite.-
Length closed (mm) 145 173 152
Length open (mm) 130 150 132
Length posted (mm) 180 208 186
Diameter (mm) 20 18 20
Weight, dry (g) 36.3 44.0 44.9


The three pens where Kubo met Sakai--years after the disappearance of the later.
Only the pen in the middle (black ebonite in the shape of bamboo) has an additional engraving--on the clip it says "NEW CLIP", showing some parts coming from Fukunaka Seisakusho. The plain black pen (on top) has no clip.

Remarkable pens with remarkable nibs, although they might not be the best match. But sure they are attractive and desirable.

My thanks to Ms. Lai.

Ebonite Feeds in Japan

This text is long overdue. This is, in essence, a correction to a couple of old posts on the Pilot (and Namiki) pens with size 50 nibs (::1::, ::2::). I said (but I cannot recall when or on which text) that their feeds were made of ebonite, and that is not correct—they are made of plastic. Actually, all feeds made by Pilot are made of plastic.


Emperor size pen by Pilot, later on labeled as Namiki.


The feed of the previous pen. It is lacquered on one side, but the material is plastic.

And not only those by Pilot, but also those by Platinum and Sailor are made of plastic. Are there, in fact, any exception to this rule? There is, but it comes from small makers and in unusual forms:

-- Eboya (formerly Nebotek) pens implement ebonite feeds on its higher end pens, but Eboya feeds and nibs are made by Bock.


Ebonite feed on a pen made by Nikko Ebonite. But the feed is made by Bock in Germany out of, probably, German ebonite. The rest of the pen is made of Japanese ebonite.

-- Masahiro creates ebonite feeds for its pens, which use Pilot nibs.

And that seems to be it. Stylo-Art Karuizawa, Hakase, and Ohashido take their nibs from the big three Japanese companies, and they do not modify the feeds. Onishi Seisakusho employs Schmidt nibs and plastic feeds.

Some old nibmeisters –and I am mostly thinking of Kubo Kohei— keep on making their nibs on demand, and their feeds are often made of ebonite, but these craftsmen do not manufacture pens regularly or according to a established model.


A nib made by nibmeister Kubo Kohei. Its feed is made of ebonite.


Nibs and feeds of a Platinum 3776 and of a Nakaya. On both cases, the feeds are made of plastic.

So, the interesting conclusion id the almost complete absence of ebonite feeds among Japanese maker. This fact does not pose any functional problem to Japanese pens with one possible exception —the irregularly behaved Pilot’s size-10 falcon nib implemented on the models Custom 742 and Custom Heritage 912. And there are powerful arguments to support the use of some plastics, mostly ABS, on feeds.


Sailor's nib and feed. The nib is made of 21 K gold. The feed is made of ABS plastic.

But for some stylophiles, ebonite feeds are the one and only way to go. And they will never be satisfied with modern Japanese pens… save for a couple of exceptions.

Mr. Iwase's Creations

Mr. Iwase is a pen aficionado who likes to decorate his pens with sea shells; that is, with raden. At the last meeting of the Wagner group in Tokyo he brought a couple of superb examples of his hobby.


The raden decorated pens based upon Momose's creations. The filling system follows the Japanese eyedropper scheme (shut-off valve manned from the tail).

The bases, in this case, are two ebonite pens made by Mr. Momose (lathe work) and Mr. Kubo (nib)—in fact a winning combination desired by many a stylophile in Japan. And then, the decoration. It is particular brilliant—note how the different stripes of raden preserve the colorful pattern of the shell.


The superb work of Mr Iwase is clearly visible on this pic. Note how the decoration preserves the color pattern of the original shell.


The nib by nibmeister Kubo Kohei. The engraving reads "Kubo / MIKADO / K18 750 / MADE IN JAPAN". The section is decorated with urushi resin, therefore the reddish color.

These are the dimensions of the flat end pen:

Length closed: 165 mm
Length open: 150 mm
Diameter: 27 mm
Weight: 67.5 g (dry)


These works by Mr. Iwase are unique pens—one of a kind. They do not appear in any catalog or book. These lines might, in fact, be one of the few records ever made public about them. And their relevance in the history of Japanese pens is merely anecdotal. But those pens are real, and their maki-e, outstanding.


The cap top is decorated with three circles meaning, according to the author, the three persons involved on the pen: Iwase, Kubo and Momose.

It is hard not to compare Mr. Iwase’s pen to that made by Zôhiko also with raden decoration. The later, let us remember, shared a similar base pen, and is valued in JPY 1200000. But this pen lacked a real nibmester’s nib, and some seriously doubt it performed as a pen. Iwase’s creation is more interesting—better decoration, better nib.

My thanks to Mr. and Ms. Iwase.

Zôhiko

There is a relatively new guy –albeit old as well— in town. Zôhiko is indeed a old company as it was founded in 1661 in Kyoto. Its original business was ivory –the in the name actually means elephant—, but with the second generation of owners the market expanded to include maki-e and related techniques and the ivory section ended up disappearing.

But only recently Zôhiko included fountain pens in its catalog of luxury goods. This happened in 2008 by means of an association with the French craftsman Michel Audiard.

More recently, around 2012, a new series of fountain pens were produced. These pens were the initiative of fountain pen entrepreneur Mr. Katayama and Zôhiko, and involved a group of unique Japanese craftsmen.


Raden, on the front, and maki-e.

Body and feed were made by Mr. Momose Yasuaki—an old, now retired, lathe master well known and respected in the Japanese scene. He was also in charge of the filling system, Japanese eyedropper (i. e. with shut-off valve), which is one of his fields of mastery.

Nibs, made of 18 K gold, carry the monogram KMK (with the first K inverted), meaning Katayama-Makino-Kubo. This is a brand name registered by Mr. Katayama. However, these Zôhiko nibs were manufactured by jeweler Mr. Tsukii Masao.


The 18 K gold nib made by Mr Tsukii Masao. Note the monogram KMK engraved on the nib.


The feed is also imprinted with the initials KMK, the registered brand by Mr Katayama.

The final assembly of the pen was made by nibmeister Kubo Kohei, well know to the readers of these Chronicles.

The maki-e decoration, finally, was commissioned to Mr Yamamoto Munori, a Zôhiko regular “in-house” craftsman.


The results of the good work of Mr. Yamamoto Munori.

The final result is an outstanding collection of maki-e decorated pens. But they do not come cheap or in large numbers. Of the raden-decorated unit, only three were made at a cost of JPY 1.200.000. Of the rest, between 4 and 6 units of each were produced. Their price is JPY 600.000, save for the unit with spiral motifs, whose price is JPY 800.000.


JPY 800.000.


Some of the pieces carry a signature, but it simply says Zôhiko.

Now, are they good pens? How do they write? The fact that a jeweler and not a nibmeister crafted the nibs is an unsettling and worrisome detail… But maybe the question is a different one: would anyone ink any of them?
