Geometry

Some days ago I spoke on these chronicles of the gold content in nibs. I inserted a link to some texts written by Prof. Antonios Zavaliangos in which he spoke of nib materials and flexible nibs. These can be made, he concluded, out of any of the usual materials—gold, steel, titanium…

This past weekend, I already spoke about it, the monthly Wagner Pen Clinic was celebrated. We pen enthusiasts met and shared our beloved objects. Nib-polishing master Peko-san came with a small selection of vintage Pilot pens--among other wonders.

One of them, the bright green celluloid one, sported this steel nib:

Please, note the shape of the breathing hole.

Line variation achievable with this nib.

Yes, a stainless steel nib.

That pens dates back to late 1950s, I guess. Certainly later than 1954, when the Japanese Ministry of industry introduced the guidelines for metallurgy –affecting pen nibs— and the JIS (Japan Industrial Standards) logo that can be seen on this pen.

Geometry matters more than material.

I have a shiro nib on a wartime pen (called Athena, by Maruzen) that is incredibly flexy. It was used a lot by its previous owner so it's also quite scratchy, so I don't use it often - but I think it has the same V-shaped breathing hole.
