Quill provides greater writing flexibility than a steel pen.
 Additionally, writing with the left hand in the era in which the quill was popular was discouraged, and quills were never sold as left- and right-handed, only by their size and species
 Although feathers from the left wing are supposedly favored by right-handed writers because the feather curves away from the sight line, over the back of the hand, the quill barrel is cut to six or seven inches in length so no such consideration of curvature or 'sight-line' is necessary
