Pens of one type or another have been used for thousands of years. Today, pens rank among the most widely used writing instruments. More than 2 billion pens are manufactured in the United States annually. There are five main kinds of pens. They are (1) ballpoint pens, (2) fountain pens, (3) soft-tip pens, (4) rolling-ball pens, and (5) specialty pens.As early as 4,000 B.C., ancient peoples used crude pens consisting of hollow straws or reeds that supported a short column of liquid. During the 500’s B.C., people began to make pens from the wing feathers of such birds as geese and swans. The shaft of the feathers was hardened, and the writing tip was shaped and slit to make writing easy. These feather pens were known as quill pens, and they were widely used until the development of steel-nib pens in the 1800’s.By the late 1800’s, inventors had perfected an early version of the fountain pen. This pen represented a major improvement over previous pens, because it featured an ink reservoir and a capillary feed. Earlier pens held only a small amount of ink at a time and had to be repeatedly dipped in ink.
