I am not talking about people who are good writers, but pens that write well. My pens I consider good writers remain filled with ink. I keep them ready for a card, letter or note. Each one of these pens deserves a quick mention.
My Karas Kustoms INK with a Franklin-Christoph Masuyama cursive italic nib writes great. The combination of heft, flow, and italic often matches my mood for quick card or note.
I often reach for my smooth writing Edison Nouveau Premiere with a stub nib when writing a letter. This beauty is the Majestic Pine special edition from Goulet Pens. This light weight pen produces less fatigue in longer writing sessions.
My next good writer is a Sheaffer Legacy with a 14k fine nib. One of my first fountain pens, I bought it new in 1995. The fine line writes smaller than the cursive italic or stub nibs.
Another good writer, my Lamy Studio, belongs in this category. I know this medium nib is the same as a Safari or AL-Star, but something about this Studio I really like. My ink choice, DeAtramentis Sherlock Holmes, matches the pen nicely.
My last good writer is my Pelikan M205 Amethyst. Another medium nib, it lays down a nice amount of ink. The first couple of fills were the matching Edelstein Amethyst ink. Then I tried Edelstein Aquamarine. Currently it is filled with Lamy Dark Lilac. All of these show nice shading coming out of this Pelikan nib. The two German competitors work together in this case.
p.s. Pick up one of your good writers and write someone a letter.
