As a lefty (with atrocious penmanship), I have a soft spot for Waterman’s Yellow nibs. In turn, the collection has steadily grown. What struck me today when looking them over is how different the nib shape and profiles are from one to another. Additionally, flexibility varies significantly.
In the close-up photos of the nibs from left to right: (1) Canadian #5. (2,3) US #7’s. (4) Canadian #7. (5) Canadian 14k #7. (6) US 18k #7.
By far, the 18k nib requires the least amount of pressure to spread the tines and lays down a strong wet line. The #5 is quite springy and flexible. The 14k nib is surprisingly the least flexible.
So, the moral of the story, when my girlfriend muses why I have 'so many of the same pen', I can now point out that they are in fact quite dissimilar. The madness continues….
