When seen in photos, the Sonnet and the 75 appear to be about the same size. However, when you are holding them both in your hand, the 75 definitely feels smaller than the Sonnet. The 75 is slightly shorter and narrower than the Sonnet.

There are many similarities in the design of these pens. The caps share the typical Parker arrow clip with an ornate "tassie" at the cap's tip. The 75 also has a "tassie" at the end of its barrel, while the Sonnet ends in a smooth bullet shape. There is an inscription of the name "Parker" at the lower end of each cap. And the sections of each pen are both black plastic.


The nibs each have their own distinctive feel, though both are great writers. The Sonnet nib was modified by Richard Binder to be a stub-italic with very good ink flow. Thus, it writes well on almost any paper that I throw at it. It is incredibly smooth and has a very large sweet spot. The 75 nib is a standard Parker medium nib. It puts down a very nice wet line as well. It has a bit of "tooth" to it, which adds just enough feedback to make for a very pleasant writing experience.

In summary, both of these pens are superb writers, though each has its own individual personality. The Sonnet, with its shiny lacquered finish, and the butter-smooth Binder nib feels very modern. It is shiny, smooth and competent. The cisele 75, by comparison, definitely feels like a vintage pen. The weathered apperance of the exterior, the texture of the metal crosshatching and the tactile feel of the toothy nib all combine to give this pen a seasoned character that is very different from the Sonnet.
Both of these pens have earned a permanent place in my pen rotations.
