Writing tools are used to create writing, drawing, painting, and technical drawing, or any other task that requires a controlled and fine line. Writing implements are classified into two broad categories: autonomous instruments and assisted instruments. The difference between the two is that autonomous instruments do not need refills. As long as the instruments exist, they are usable. Examples of autonomous writing tools include pencils, crayons and chalk. Assisted writing instruments require the addition of pigment in order to produce writing, and examples of these instruments are pens, mechanical pencils, and brushes. A modern day example of an autonomous instrument that does not use pigment to make a line is the stylus used for create text on hand held computers.
Assisted writing implements have hardened tips that apply pigment onto a surface. Usually, the instrument has a reservoir to hold the pigment. Up until the Nineteenth Century, quill pens were standard in Europe and North America. Capillary action drew the ink into the hollow quill and thereby created a small reservoir. The quill pen evolved into the fountain pen, which is still used today. While Western countries were developing versions of pens or pencils, Eastern civilizations preferred the finely modulated flow only achievable with a brush. An innovation that combines the qualities of both Western and Eastern instruments is the brush pen. The brush handle contains a reservoir that can be refilled from a bottle of ink or prepared cartridges. Including the computer, most writing instruments nowadays have a built in obsolesce, which results in a reliable market for manufactures and wholesalers.
