Knock

The Platinum Knock-18 is one of those mysterious fountain pens. The books say it existed, you can even see some pictures of it in the Internet, but it is quite unlikely to run into it for real.


The Platinum Knock 18.

Last Sunday, at the monthly Wagner Pen Clinic I had the chance to put my hands in one of them.

The Knock 19 compared to the 1965 Pilot Capless model. The later, in red, is about 1 cm longer.

The push buttons are totally different. While the Pilot has a relatively small button entering the barrel, in the Platinum pen, the whole barrel is the button.

Transparent feeders on both nibs. Platinum nib moves further out from the section than Pilot's.

The openings for the nibs. Both are closed when the pen is not in use, although that cannot be seen on the pic.

Pilot marketed its first Capless model in 1963 at a whooping price of JPY 6000, which could be something in the order of JPY 60000 nowadays. Given the limited success, a JPY 3000 version was released the following year –aiming at students, some sources say— and it became a real success. Platinum then made its own model –this Knock 18— trying to take benefit of the new trend. This model was short-lived due to patent infringement issues.

My thanks to Mr. Niikura, who allowed me to inspect his never inked pen.

Curioso. Por la copia de Platinum y por los cargadores transparentes. Seguramente serán muy comunes hoy en día, pero me sorprende que existieran en aquella época.

Por cierto, correción ejecutada en el post de los onsen. Mercy.

Here's the US patent from 1965/66 by
Shunichi Nakata for the 'retractable closure for pen casings':

By the way, I love your blog.
