Pens are recorders, with which a write liquid, ink, is usually laid on to describing off on as for instance paper.

Originally for it course-sharpened keels were used by bird feathers/springs. They had often to be cut with a sharp Federmesser more briefly (therefore it today still the "“small blade"” with Taschenmessern).

According to the kind of the produced write course different kinds are differentiated from pens.

Tape strain feather/spring

The use of tape strain feathers/springs, also broad feather/spring or change tension spring mentioned, makes writings with direction-controlled changes for the line strength possible. The maximally possible line strength corresponds thereby the feather/spring width. There are diagonal and straight tape strain feathers/springs, which result in different line strengths dependent on the angle of the feather/spring beginning regarding the writing direction.

Examples:

• broad-sharp-edged cut feather/spring keels
• steel broad feather/spring after Blankertz

Tape strain feathers/springs are used and typically in the Kalligrafie.

Pointed feather/spring

The pointed feather/spring, also swelling tension spring, is a pen, which on and abschwellenden by their elasticity with different write pressure a typeface with lines, which can produce swelling course so mentioned.

The steel pointed feather/spring spread from England, where it was used for the letter of the English script (Anglaise), to Germany. The typeface of the German Kurrentschrift was coined/shaped over centuries by the pointed feather/spring.

The pointed feather/spring has not like today usual pens at the end a small ball, but runs in a sharp, along slit point. This design requires a special write technology. When implementing an upswing, i.e. when pushing the feather/spring upward, only a very low pressure may be exerted on the Federspitze, since the feather/spring would remain being otherwise in the paper. With the wing over, i.e. when pulling the feather/spring downward, a stronger pressure is exerted on the feather/spring, whereby the Federspitze aufspreitzt themselves and is released so more ink. Thus a stronger line than during develops the upswing with the wing over. Also it is important that during the writing with the pointed feather/spring of the penholders in the correct angle one holds.

There are pointed feathers/springs only for penholders without ink filling system (ink cartridges or piston stylograph). For stylographs they are today no longer available, since they are usually no longer usual in the today's time for the everyday life use.

Equal tension spring

The invention of the equal tension spring, also cord tension spring or Redisfeder, with spherical head made possible the development today used of the writings with equivalent line width. It is the write tool, with which learning is made possible for one of the today usual output writings. By its use at school it is the pen usually-used today. The writing is essentially durable in relation to different attitudes of the feather/spring.
