It all depends…
Having attended a typing class in my early education (remember the Royal manual typewriter?), I found it easy to make the translation to PC keyboards. When my head is filled with data I need to “download” this is my preferred method. If I have a string of ideas which need quick safekeeping for further development later on, using a PC keyboard is my choice.
Pens are another matter. I have long been hard to please when it comes to ink pens. Ballpoint is my preference for daily work, but being left-handed limits my choices. I can’t use thick-barreled pens. Also, a rubberized grip is vital. Gel ink or felt-tips are out of question altogether. I also like a fine point; the finer the better. Pilot makes a fine-tip ballpoint with rubber grip that is my ideal writing instrument at the moment.
Pencils. Blackfeet writing pencils are a great choice. I like a dark line and Blackfeet is excellent. Also, some recent pencil developments include a sort of “synthetic wood” which I don’t care for. A “real” old-fashioned wooden pencil is my choice.
Finally, when it comes to pens and pencils, I use them when I’m in the composing stages of a project. They “slow down” my writing so that my thoughts have a chance to lag behind a bit and develop. This results in more useful and creative copy. If I were to use a keyboard, my creativity would be outrun by my finger speed. To ensure better initial drafts I always compose in longhand.
