Dip pen in the context of "Bone"

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 Reed pens, quill pens and dip pens, which were used for writing, have been replaced by ballpoint pens, rollerball pens, fountain pens and felt or ceramic tip pens.

Ruling pens, which were used for technical drawing and cartography, have been replaced by technical pens such as the Rapidograph.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 nib is the part of a quill, dip pen, fountain pen, ball point, or stylus which comes into contact with the writing surface in order to deposit ink. Different types of nibs vary in their purpose, shape and size, as well as the material from which they are made.

An inkwell is a small jar or container, often made of glass, porcelain, silver, brass, or pewter, used for holding ink in a place convenient for the person who is writing. The artist or writer dips the brush, quill, or dip pen into the inkwell as needed or uses the inkwell as the source for filling the reservoir of a fountain pen. An inkwell usually has a lid to prevent contamination, evaporation, accidental spillage, and excessive exposure to air. A type known as the travelling inkwell was fitted with a secure screw lid so a traveller could carry a supply of ink in their luggage without the risk of leakage.

A ballpoint pen, also known as a biro (British English), ball pen (Bangladeshi, Hong Kong, Indian, Indonesian, Pakistani, Japanese and Philippine English), or dot pen (Nepali English and South Asian English), is a pen that dispenses ink (usually in paste form) over a metal ball at its point, i.e., over a "ball point". The metals commonly used are steel, brass, or tungsten carbide. The design was conceived and developed as a cleaner and more reliable alternative to dip pens and fountain pens, and it is now the world's most-used writing instrument; millions are manufactured and sold daily. It has influenced art and graphic design and spawned an artwork genre.

A fountain pen is a writing instrument that uses a metal nib to apply water-based ink to paper. It is distinguished from earlier dip pens by using an internal reservoir to hold ink, eliminating the need to repeatedly dip the pen in an inkwell during use. The pen draws ink from the reservoir through a feed to the nib and deposits the ink on paper via a combination of gravity and capillary action. Filling the reservoir with ink may be achieved manually, via the use of an eyedropper or syringe, or via an internal filling mechanism that creates suction (for example, through a piston mechanism) or a vacuum to transfer ink directly through the nib into the reservoir. Some pens employ removable reservoirs in the form of pre-filled ink cartridges.

Sir Josiah Mason (23 February 1795 – 16 June 1881) was an English industrialist, engaged in dip pen manufacture and other trades, and a philanthropist. He founded Mason Science College in 1875, which later became the University of Birmingham.

A ballpoint pen, also known as a biro (British English), ball pen (Bangladeshi, Hong Kong, Indian, Indonesian, Pakistani, Japanese and Philippine English), or dot pen (Nepali English and South Asian English), is a pen that dispenses ink (usually in paste form) over a hard ball at its point, i.e., over a "ball point". The materials commonly used are steel, brass, or tungsten carbide. The design was conceived and developed as a cleaner and more reliable alternative to dip pens and fountain pens, and it is now the world's most-used writing instrument; millions are manufactured and sold daily. It has influenced art and graphic design and spawned an artwork genre.
