When I was little, I was often writing with a very short stubby pencil - I like the feel and look of a very soft dark pencil [ED. And stubbiness is the price one pays for this preference!].
More generally, in adulthood, I prefer to write with something whose physical substance can be strikingly perceived as it transfers from the writing implement to the page: the Gelly Roll pens are very good, they leave a lovely thick glistening three-dimensional trail like a snail's!
