I stumbled across this today, haven’t yet watched it all.
Neil is known in FP circles for using Fountain Pens, notably the Pilot 823 - for both his writing and his signings. In this Tim Ferris interview (1’ 37”), Neil talks about why he likes to use fountain pens. Some of his answers are the same as those any of us here would give, but he also talks about how fountain pen use has shaped his writing.
I’d watch a Neil Gaiman interview just to hear him speak about his work, but this fountain pen bit in the Ferris interview...more than worth the time to hear one of Earth’s greatest writers talk about Earth’s greatest writing tool.
