Blue Kaweco Student, EF nib with Waterman Serenity Blue ink. Recently dropped this pen and, of course, it landed on the nib. The EF just came in and it's so nice to have this back in rotation.
What is in my pocket and what I have used may not be the same. Used: TWSBI 580 B stub, TWSBI Eco 1. 1, Parker 45 Flighter M inked with KWZI El Dorado, Lamy Pacific and Sheaffer Skrip Emerald Green respectively. In my pocket but remains unused today 3776. 80
