A writing implement or writing instrument is an object used to produce writing. Writing consists of different figures, lines, and or forms. Most of these items can be also used for other functions such as painting, drawing and technical drawing, but writing instruments generally have the ordinary requirement to create a smooth, controllable line.
Another writing implement employed by a smaller population is the stylus used in conjunction with the slate for punching out the dots in Braille.
A pen is a common writing instrument that applies ink to a surface, typically paper, for writing or drawing. Early pens such as reed pens, quill pens, dip pens and ruling pens held a small amount of ink on a nib or in a small void or cavity that had to be periodically recharged by dipping the tip of the pen into an inkwell. Today, such pens find only a small number of specialized uses, such as in illustration and calligraphy. Reed pens, quill pens and dip pens, which were used for writing, have been replaced by ballpoint pens, rollerball pens, fountain pens and felt or ceramic tip pens.
Ruling pens, which were used for technical drawing and cartography, have been replaced by technical pens such as the Rapidograph. All of these modern pens contain internal ink reservoirs, such that they do not need to be dipped in ink while writing.
A quill is a writing tool made from a moulted flight feather (preferably a primary wing-feather) of a large bird. Quills were used for writing with ink before the invention of the dip pen/metal-nibbed pen, the fountain pen, and, eventually, the ballpoint pen.
As with the earlier reed pen (and later dip pen), a quill has no internal ink reservoir and therefore needs to periodically be dipped into an inkwell during writing. The hand-cut goose quill is rarely used by modern calligraphers, however, it is still the tool of choice for a few scribes who claim the quills provide an unmatched sharp stroke as well as greater flexibility than a steel pen.
A Chinese writing brush (traditional Chinese: ๆฏ็ญ; simplified Chinese: ๆฏ็ฌ; pinyin: mรกo bว) is a paintbrush used as a writing tool in Chinese calligraphy as well as in Japanese, Korean, and Vietnamese which all have roots in Chinese calligraphy. They are also used in Chinese painting and other brush painting styles. The ink brush was invented in China around 300 B.C. Together with the inkstone, inkstick and Xuan paper, these four writing implements form the Four Treasures of the Study.
