From an article in the Atlantic from a few years ago:
The ballpoint’s universal success has changed how most people experience ink. Its thicker ink was less likely to leak than that of its predecessors. For most purposes, this was a win—no more ink-stained shirts, no need for those stereotypically geeky pocket protectors. However, thicker ink also changes the physical experience of writing, not necessarily all for the better.
I wouldn’t have noticed the difference if it weren’t for my affection for unusual pens, which brought me to my first good fountain pen. A lifetime writing with the ballpoint and minor variations on the concept (gel pens, rollerballs) left me unprepared for how completely different a fountain pen would feel. Its thin ink immediately leaves a mark on paper with even the slightest, pressure-free touch to the surface. My writing suddenly grew extra lines, appearing between what used to be separate pen strokes. My hand, trained by the ballpoint, expected that lessening the pressure from the pen was enough to stop writing, but I found I had to lift it clear off the paper entirely. Once I started to adjust to this change, however, it felt like a godsend; a less-firm press on the page also meant less strain on my hand….
Sassoon’s analysis of how we’re taught to hold pens makes a much stronger case for the role of the ballpoint in the decline of cursive. She explains that the type of pen grip taught in contemporary grade school is the same grip that’s been used for generations, long before everyone wrote with ballpoints. However, writing with ballpoints and other modern pens requires that they be placed at a greater, more upright angle to the paper—a position that’s generally uncomfortable with a traditional pen hold. Even before computer keyboards turned so many people into carpal-tunnel sufferers, the ballpoint pen was already straining hands and wrists.
Ballpoint pens seem to have been superseded by gel pens or roller ball pens, which don’t require quite the same grip or pressure on the page. But somehow I don’t think that cursive will come back as a result. And frankly, I don’t think that the characters of the Palmer Method are all that attractive. I really wish that the Society for Italic Handwriting had been more influential.
