Even Rarer

Long time ago I wrote about one of those mysterious pens—a pen that is known to exist but that is so rare that has become almost mythical. That was the Platinum Knock, Platinum's take on the idea of a capless pen.


Platinum Knock-18. 18 K gold nib, JPY 3000, 1965.

That pen, marketed initially in 1965, was short lived due to the threats of Pilot to start legal actions. However, there were two versions of the pen: the initial one from 1965, and a second variation with a lighter cut-out clip in 1966.


The two versions of the Platinum Knock. From a panel at the temporary exhibition at Itoya Ginza (January-February 2019).

And now, thanks to a temporary exhibition on the history of Platinum hold at Itoya Ginza in Tokyo we can see that there existed an even rarer pen—the demonstrator version of the capless Platinum Knock.


The demonstrator version. Did it ever make its way to the street, even in the hands of a salesman?

So, let this be heard—there are transparent versions of the Platinum Knock, even if they were only prototypes.

Nagahara 2020

The bare news:

Nibmeister Yukio Nagahara will retire from his current position in Sailor in February of 2020. He plans to pursue an independent career under the name “The Nib Shaper”. Nagahara is already preparing the website of this new operation.



Who will succeed Nagahara in Sailor?

Ohashido (I)

Besides the big three Japanese pen companies –Pilot-Namiki, Platinum-Nakaya, and Sailor– there are a bunch of small operations, some of which I have described on these Chronicles: Masahiro, Eboya,... I haven't spoken much about Ôhashidô, and that despite being very active in the local (Japanese) market.

Ôhashidô –Ôhashidô Ltd.– was formally founded in 1965, but it has its origins in Tokyo in 1912, when Yoshiharu Uemura open his workshop in Asakusa while working for SSS, the big company of the time. He moved to Sendai, about 300 km north of Tokyo, after the Big Kanto Earthquake in 1923 to work with inventor Kazuyoshi Hiratsuka. The new shop was located close to the Big Bridge (Ô-hashi) over the river Hirose. Ôhashidô means “the hall of the big bridge”.

The business was completely destroyed during the War. The operation revived around 1950 in the hands of Yoshiharu's son Eiichi Uehara, but not through manufacturing pens but by fixing them. The production of pens was resumed some years later, and by 1965 Ôhashidô Ltd. started formally.

In 2010, Eiichi's son Yûichi Uehara took control of the company. He has become very active in the Japanese scene by attending a big number of sale events hosted by stationers and department stores where he sells his pens directly.

Ôhashidô's operation is quite unique. It seems anchored in the pre-industrial era. There is barely any system in the production: there are no model names, the warranty card is just Uehara's business card, there are no instruction sheets, etc... Contacting him is not easy either—he has no public email address, and only very recently he open a website (https://ohasibo.theshop.jp/).

As for the pens, they are made mostly in ebonite –sometimes from Nikko Ebonite, some other from old stocks of unclear origin--, and implement Sailor nibs of sizes medium and big (following Sailor names) in both 14 K and 21 K grades. In fact, for some time, Ohashido offered big nibs made of 14 K gold, which was not an option on Sailor pens. In a more distant past, Ohashido used nibs by Ishiwaka Kinpen Seisakusho, Kabutogi Ginjiro, and even Ishi Shoten (Yotsubishi). Some sources also speak of nibs made by Eiichi Uehara himself.

All current Ôhashidô pens use Sailor cartridges and converters. The later, at least, if the barrel was big enough, of course.

And on another Chronicle I will describe some Ôhashidô pen in detail.
