From The New Yorker:
Cormac McCarthy purchased a powder blue Olivetti Lettera 32 mechanical typewriter in a Tennessee pawnshop, in 1963, for fifty dollars, and used it for the next five decades, producing an estimated five million words tickling its ivories. An author’s instrument is more than a tool; it is an extension of his very soul. With that in mind, choose your weapon carefully. (I use the Olivetti Lettera 22—an earlier model—myself.)
Ballpoint pen: Let me guess—you probably have a great idea for a book that you’ve been meaning to write but haven’t actually got around to starting?
Fountain pen: You don’t use contractions because you think that they degrade the language, and your epigraphs are all in Latin. You include epigraphs in everything you write.
. . . .
Manual typewriter: You spent six hundred dollars on a typewriter that you’ve used twice.
No. 2 pencil: You keep one behind your ear because you think it looks writerly, but exclusively use it to jot down to-do lists.
Pencil you can only sharpen with a pocket knife: You have gone camping two or three times in your life and bring it up at least once per conversation.
