A '''writing implement''' or '''writing instrument''' is an object used to produce [[writing]]. Most of these items can be also used for other functions such as [[painting]], [[drawing]] and [[technical drawing]], but writing instruments generally have the unique requirement to create a smooth, controllable [[line]].
==Autonomous writing instruments==
These have an inherent functionality in that their useful life corresponds to their length of their physical existence, i.e. they cannot "run out" and persist as useless objects.
===Without pigment===
The oldest known examples of writing were created by incising a flat surface with a rigid tool rather than applying pigment with a secondary object, e.g., Chinese [[jiaguwen]] carved into turtle shells. However, this may simply represent the relative durability of such artifacts rather than truly representing the evolution of techniques, as the meaningful application of pigment is attested in prehistoric cave paintings such as the ones at [[Lascaux]]
The ancient [[Sumerian language|Sumerians]] and their successor cultures, such as the [[Babylonians]], produced their [[cuneiform]] writing by pressing a triangular [[stylus]] into soft clay tablets, creating characteristic wedge-shaped marks. The clay tablets were then baked to harden them and permanently preserve the marks.
Several other ancient cultures such as [[Mycenaean Greece]] also inscribed their records into clay tablets but did not routinely bake them; much of the [[Linear B]] corpus from [[Minoan Crete]] was accidentally preserved by a catastrophic fire which hard-baked those tablets. The [[Ancient Rome|Romans]] used [[lead]] styli with [[wax tablet]]s which could be "erased" by rubbing the [[beeswax]] surface smooth again.
In the modern era, [[Hand-held computer|hand held computer]]s and certain other computer [[input device]]s use a stylus to enter information onto a screen by applying pressure rather than by depositing pigment.
Words and names are still commonly inscribed into commemorative objects, such as the [[engraved]] winners' names on the [[silver]] [[Stanley Cup]] or the [[Gettysburg Address]] carved into the stone wall of the [[Lincoln Memorial]], but the requisite tools are not exclusively considered to be writing instruments.
===With inherent pigment===
The original form of "lead [[pencil]]" was the lead stylus used by the ancient Romans, who also used it to write on wood or papyrus by leaving dark streaks where the soft metal rubbed off onto the surface. However, most modern "lead [[pencils]]" have a nonpoisonous core of greyish-black [[graphite]] mixed with various proportions of [[clay]] for consistency, enclosed within an outer wooden casing to protect the fragile graphite from being snapped apart or from leaving marks on the user's hand.
White [[chalk]] has been traditionally used in [[schoolroom]]s to write on a main [[blackboard]] at the front of the room. In the 19th century, and indeed well into the 20th century, when paper was less readily available, individual students also wrote with chalk on their own small [[slate (writing)|slate]]s.
Both pencils and chalk exist in variants which can create marks in other colors, but colored pencils and colored chalk are generally considered to be [[art supplies]] rather than writing instruments. Similarly, although very young children may use colorful wax [[crayons]] to write words into their pictures, writing is not considered to be the primary use of crayons.
A [[wax pencil]] resembles both a crayon and a pencil in that it contains a brightly colored wax core within a protective paper casing, but its proportions are closer to that of a standard pencil. Wax pencils are primarily used to write onto nonporous surfaces such as [[porcelain]] or [[glass]].
Normal pencils, chalk, and crayons all share the characteristic that they cannot "run out". The useful life of these implements is closely linked to their physical existence.
==Assisted writing implements==
These require the presence of an added pigment in order to write, and are useless when "empty".
===Pens===
The pen is the most common form of writing implement. It has a hard tip which applies ink to a surface.
====Capillary-action dip pens====
Initially, pens were made by slicing a suitable [[nib]] point from the end of a thin, hollow natural material which could retain a small reservoir of ink by [[capillary action]]. However, these ink reservoirs were relatively small, requiring the pen to be periodically dipped back into an external [[inkwell]] for replenishing.
[[Reed pens]] were used by the ancient Egyptians to write on [[papyrus]]. [[Quill]] pens were standard in Europe and the United States up through the 18th and 19h centuries, and are still used in various contexts, such as [[calligraphy]] and formal settings such as major [[bank]] transactions. The most common quills were taken from the wings of [[geese]] or [[ravens]], although the feathers of [[swans]] and [[peacocks]] were sometimes favored for prestige.
A [[dip pen]] has a steel nib - the pen proper - and a pen-holder. Dip pens are very versatile, as the pen-holder can accommodate a wide variety of nibs that are specialized for different purposes-- [[copperplate]] writing, mapping pens, and five-pointed nibs for drawing [[Staff (musical)|music stave]]s-- and can be used with most types of ink, some of which are incompatible with other types of pen. Automatic pens are a category of dip pen, in which the nib is in two parts and can hold a larger quantity of ink. However, like all of its precursors, the steel-nibbed dip pens had a limited ink reservoir and a tendency to drip inkblots on the page.
====Fountain pens====
[[Fountain pens]] were developed in the 19th century. These consist of the nib unit, an ink reservoir chamber, and an external casing. The casing usually includes a cover for the nib, in order to protect its shape and keep the ink from evaporating dry or wicking into the user's pocket. Depending on the design of the pen, the ink reservoir can be filled in several different ways: direct addition by eyedropper, suction from an internal mechanism, or disposable pre-filled cartridges. Some cartridge-based fountain pens can be fitted with "converters", which are separate piston/suction reservoirs of the same dimensions as the pen's usual refill cartridge; these allow the pen to refill from bottled ink.
Only certain types of ink can be used in a fountain pen, to avoid clogging up the nib unit mechanism. Although the larger reservoir of fountain pens requires less frequent ink replenishment, the ink may inconveniently spill out in certain contexts to stain the paper, fingers, or clothing of an unwary writer. Differences in air pressure may cause spectacular effects when travelling by airplane.
====Disposable pens====
A large number of new pen types were popularized in the 20th century. Some of them are not constructed to be refilled with ink after they run dry; although others can theoretically have their internal ink compartment replaced, the widespread custom is to simply throw away the entire pen when its ink is no longer accessible.
These types include the [[ballpoint pen]] (often called a [[Laszlo Biro|biro]] in many Commonwealth countries) and the [[felt tip pen]]. Both of these have subtypes which are popularly called by their own specific names, usually based on the type of their ink, such as the fluorescent [[highlighter]], the [[rollerball pen]], and the [[gel pen]].
===Mechanical pencils===
Unlike the construction of a traditional wooden pencil around a solid graphite core, a [[mechanical pencil]] feeds a small, mobile piece of graphite through its tip. An internal mechanism controls the position of the graphite by friction, so that while it remains steady while writing, the graphite can be advanced forward to compensate for gradual wear or retracted to protect it when not in use. The graphite in mechanical pencils is typically much narrower than in wooden pencils, frequently in sub-[[millimeter]] diameters. This makes them particularly useful for fine diagrams or small handwriting, although different sizes of refill leads cannot be interchanged in the same pencil.
===Brushes===
Although in Western civilization writing is usually done with some form of [[pencil]] or [[pen]], other cultures have used other instruments. [[Chinese written language|Chinese]] characters are traditionally written with a [[ink brush|brush]], which is perceived as lending itself to a graceful, flowing stroke.
A brush differs from a pen in that instead of a rigid nib, the brush is tipped with soft bristles. The bristles are gently swept across the paper with just enough pressure to allow ink to wick onto the surface, rather than mashing down the brush to the extent of substantial friction resistance. Although pens with semi-flexible nibs and liquid ink can also vary their stroke width depending on the degree of applied pressure, their variation range is far less obvious.
Traditionally, brushes have been loaded with ink by dipping the bristles into an external pool of ink on an [[inkstone]], analogous to a traditional dip pen with an inkwell. Some companies now make "brush pens" which in that regard resemble a fountain pen, with an internal ink reservoir built into the handle which can be refilled with preloaded cartridges or a bottle-fill converter.
==Accessories==
Other implements indirectly associated with writing include [[eraser]]s for pen and pencil, [[pencil sharpeners]], [[inkwells]], [[blotter paper]], and [[ruler]]s and related [[stationery|drawing instrument]]s. [[Pounce pot]]s were a precursor of [[blotting paper]], being a dispenser for powdery material for drying the ink. [[Stencil]]s can be used to create standardised letters, patterns or signatures.
