Hello to all,
Using JoWo nib sizes for reference, I find the #6 JoWo nib is comparable in size to Parker Duofold Centennial, modern Onoto #7, Montblanc 146, and Pelikan M800 nibs. The JoWo #8 seems to be comparable to the Montblanc 149 and the Pelican M1000.
The JoWo #5 seems comparable to the Pelikan M600, the Parker Duofold International, and many others including a lot of my vintage pens.
I have seen that JoWo makes even larger nibs like a #10 and #12. What pens use nibs that large? And can you give further examples of pens with nibs comparable to the JoWo #6 and #8 nibs?
