Quill provides greater flexibility than a steel pen.
 The process of making a quill from a feather involves curing the shaft to harden it, then fashioning its tip into a nib using a pen knife or other small cutting tool
 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
