One of the best creators of classic fountain pens is the Parker Pen Company. I have several models of both ballpoint and fountain pens.
Among my favorites, for style, class, and writing those missives requiring a solid signature, is the Parker Sterling Silver Sonnet.
It definitely makes a statement, not only in writing, but in the verbal appreciation of others who will compliment you on your taste.
Use it for your journal, use it to sign checks.
Whip this one out at your next contract signing, and you will definitely be thought of as a VIP bachelor.
