Size 6

Hoshiawase (星合せ) pens have already been covered on these chronicles. And although they are indeed original and interesting —albeit a dead end in the evolution of pens— there is only that much you can say about them. Once the description of the sealing system of the ink deposit, remember these are eyedropper pens, the rest is merely an account of the nib characteristics and of the body material and decoration.

However, that might be the fate of most fountain pens. After all, few truly innovative features there existed on this world, and those have been implemented on many different pens. In this regard, the star system has the merit of having been used only by Pilot.

The BCHR eyedropper by Pilot, from 1924.

The size 6 nib. On the section, the two stars can be seen uncrossed. Therefore, the ink channel was open.

Today´s hoshiawase pen sports a big nib—a size 6 nib. Although not the biggest for these pens, some size 8 have been reported, this is indeed a remarkable and rare pen. It dates from 1924, and its sealing system shows the earlier scheme of the hoshiawase.

An early form of hoshiawase. The element limiting the rotation of the cylinders in the section is very exposed. On later pens, this element was encircled by a groove on the outer cylinder.

As for the body, it is a black chased hard rubber (BCHR) pen.

All the elements in this pen are in pristine condition, and I doubt the owner would ever ink it.

My thanks to Mr. Niikura and to FPN member Nikolaos.

Shut-off Valve

Eyedropper pens with shut-off valve are a very Japanese idea, we all know by now. This idea is, in essence, a simplification of the plunger filler implemented by Onoto on the fountain pens arriving in Japan around 1900. The plunger filler is no longer there, and the tail knob now operated the axis moving the cone that opens and closes the connection between the ink deposit and the section.

Mostly all Japanese companies used this mechanism at some point. Some examples have been shown on these chronicles: Asahi-Tsubasa, Ban-ei, The Eiko, New Clip, Pilot-Namiki, Platinum, Platon, SSS, (Japanese) Swan,… As of today, Pilot-Namiki, Nebotek and Danitrio still make this type of shut-off valve.

SSS in black ebonite. The sealing cone is visible inside the barrel.

Swan (Japan) number 5. The section is disassembled from the barrel. The sealing cone and its axis are visible.

However, my experience using these pens is very limited. Their weakest point is the seal between the axis and the top end of the ink deposit. This thin rod must slip up and down through this seal to allow the ink to pass through the valve to the section and the feed. Traditionally, this seal was made of cork and lack of use and the passing of time are good arguments for ink leaks. In such case, these pens become very messy—ink would leak through the tail knob when turning it to open the valve.

The tail knob of the Danitrio Ban-ei.

After trying with some vintage pens –a SSS made of ebonite, with stained results—I decided to ink a Danitrio Ban-ei. Being modern, it is in good shape and there are no leaks. Then, how does it perform?

Its nib is a very smooth unit made by Kabutogi Ginjiro. It is nicely wet—as long as the there were ink actually flowing through the feed. So, in principle, this pen performs well—open the valve, uncap the pen, write. However, sealing the ink deposit when not in use has some side effect—the nib quickly becomes dry. My contention is that the lack of connection between nib and deposit deprives the first of a permanent supply of ink. Then, the natural evaporation simply dries the nib up and this space cannot be refilled with more ink from the deposit. If stored with the valve open, the nib does not become dry.

I wonder if that was the case with other eyedropper pens with shut-off valve.

PCJ-Wagner Pen Show 2012

Spring is here, despite the weather conditions, and Spring is the season for the pen show organized by the Pen Collectors of Japan (PCJ) and the Wagner group. It will take place on the weekend of April 21st and 22nd at the KFC Hall (KFC Rooms, 11th floor, room 115) in Ryogoku, Tokyo. (Please, check those links for access maps).


The entry fees are JPY 2000 for Saturday (open from 10:00 to 17:00) and JPY 1000 for Sunday (from 9:30 to 16:30). The table fee for traders is JPY 10000 for the whole weekend (more information, on pelikan@hotmail.co.jp). Apparently, there are no limitations of space and there is no need to book in advance—to trade, just show up at 9:00 on Saturday and pay the fee. The tables and the location in the room are decided on a first come, first serve basis. And this year there seems to be no special requisites to participate as a trader. Maybe we would see some coming from overseas to make this show international. Despite the interest of Japanese stylophiles for Western pens, mostly German, trading in Japan seems to be a very domestic business…

On Blogger

This blog is hosted by Google and uses the tools of Blogger.com. It was an easy decision when I started these texts. At first, you only want something easy and ready available, and eager to write as I was when starting, I did not do much search.

However, after two years in this activity, after having learned a couple of things, Blogger is indeed not up to the challenge. Google/Blogger insists in implementing cosmetic changes in the interface, but the actual problems –mostly in the editor and in the composition— have never been tackled nor solved.

Some complaints have also been raised on the problems to publish comments to these texts, and this shows a great lack of support for us, blog authors, and for its own service. Blogs are fed and fueled by comments, and these issues are very discouraging.

I wonder, therefore, if Google were really interested in keeping this service. I know now that Blogger is not a sensible option for anyone thinking of starting in this. Maybe blogs are not fashionable anymore and they do not attract enough money or attention… However, there are many other servers and options in the market.

At the Museum (V)

(As seen at the Kanagawa Prefectural Museum of Modern Literature).

The pens I am showing today belonged to HOTTA Yoshie (堀田善衛, 1918-1998). His name might click on some science-fiction aficionados’ minds by nothing that he, together with FUKUNAGA Takehiko (福永武彦, 1918-1979) and NAKAMURA Shinichiro (中村真一郎, 1918-1997), authored the seminal novel of the character Mothra (Mosura, モスラ) in 1961: The Luminous Fairies and Mothra (発光妖精とモスラ, Hakko Yosei to Mosura, originally published as a serial novel in Asahi Weekly in 1961, republished in 1994).

An Onoto with a size 5 nib.

Hotta was also an Akutagawa Prize winner in 1951 for his novel Loneliness in the Square (広場の孤独, Hiroba-no kodoku). In 1977, he received the Osaragi Jirô Award for his comprehensive biography of Spanish painter Francisco de Goya (ゴヤ, Goya, 1974-1977).

The B nib of Pelikan 400.

His better known work, however, is Judgment (審判, Shinpan, 1963), a novel on the atomic bomb of Hiroshima.

A Pilot Custom in Sterling silver, and a Pilot Elite.

Regarding his pens, we see both European and Japanese units. An Onoto with a size 5 nib; three Pelikan, a Faber Castell, and two Pilot. On the Pelikan, an extra fine Kugel (KEF) and a B points.

5 mm.

Not so long ago, I spoke about the second generation of Pilot´s Petit-1. Sometime along 2011, should we remember, this pen had been modified in two ways: reducing the number of colors from 14 to 5, and adding four notches to the barrel to secure the cap when posted. Now, quite unexpectedly, some new changes can be seen on this pen and we can speak of a new generation of Petit-1.

Two are the visible changes:

3rd, on top, and 2nd generation, on bottom, of Petit-1 pens. Note the longer barrel of the newer pen.

First, and more visible, the barrel is now 5 mm longer. As a result, the cartridge can be stored inside without actually inking the pen. This makes the packaging of this pen easier for Pilot—the pens are now sold without any bag. The sealed cartridges carry a plastic piece to avoid inking the pen accidentally. The instructions, mostly how to remove this safety piece and how to ink the pen, are written on a sticker attached to the pen. However, these extra 5 mm in the barrel are not enough for the pen to use regular Pilot cartridges nor any of the Pilot converters.

All three generations of this pen: 3rd on top, 1st on bottom. Note the yellow plastic piece on the cartridge of the third generation. It prevents accidental inking of the pen.

The packaging of the three generations of Petit-1. Newer on top, old on bottom. The first generation was inked before delivered.

The second variation is on the number of colors and variations this pen is available. The second generation was found on five different body colors that did not necessarily match the eight inks available in the cartridges that are specific for this pen. This third generation is available in eight colors, shown on clip and barrel, matching the available inks.

The new eight colors of the 3rd generation Petit-1. They match the existing line of ink colors in the Pilot Petit line of pens.

The price –JPY 210— has not changed. It is the same as for the nominally disposable Vpen (Varsity in some markets) with which the Petit-1 shares the nib.

These are the dimensions:

............................2nd generation.................3rd generation
Diameter: .......................13 mm.................................13 mm
Length closed:............. 104 mm.............................. 109 mm
Length open:.................. 90 mm ................................95 mm
Length posted:............. 128 mm ..............................133 mm
Weight (inked):................. 9.9 g .................................10.4 g

It seems this longer barrel obeys mostly to the simplification of the packaging, but at the same time it makes this pen more comfortable to use.

Size 10, by Waterman

Nibmeister Yamada is an avid, and brilliant, collector of early Waterman pens. His collection includes a couple of units with size-10 nibs—and unusual and spectacular nib. The pens are eyedroppers (model 20) with a large ink capacity.

Another view of the impressive collection of early Watermans of Mr. Yamada.

The two pens with size-10 nibs.

The two nibs have different engravings.

The 500-yen coin has a diameter of 26.5 mm, a bit over one inch.

In a sense, these Watermans would be the inspiration for the Japanese jumbo pens of the 1930s. However, their purposes were probably different—a symbol of status on the American pen, and a way to ease the grip in the case of the Japanese tools.

My thanks to Mr. Yamada.
