1. Pen tip
The nib of a fountain pen can be said to be the most critical part of a fountain pen. There are various variations from thin to thick. Generally, the most common pen nib sizes are “B (Broad thick), M (Medium medium thick), FM (Fine- Medium fine), F (Fine fine), and EF (Extra-Fine extra fine)” mainly.
From thick to thin, it is B> M> F> EF, and the size of the nib varies slightly from manufacturer to manufacturer. In the same size unit, the nib of a Japanese fountain pen will be thinner than that of a European fountain pen.
According to the usual writing habits, Westerners mostly use M nibs for fountain pens and B nibs for signatures. Because of the complicated strokes in Chinese writing, F or finer EF nibs can generally be used.
2. Grip position
The component formed by covering and fixing the nib and the tongue with a tubular material is called the grip position. The grip position is closely related to the comfort of the grip. In addition to the common circular cross-section, various ergonomic designs often contain the designer’s ingenuity. In addition, the grip’s friction, hardness, size, shape, and feel of writing are closely related.
The tubular structure that connects the holding position and covers the ink storage device is called the pen barrel. The material and shape of the pen barrel are changeable. The design is divided into general size and short rod. When writing with a short rod, the cap is placed on the end of the rod. The increased length makes it more comfortable to hold and write.
4. Sheung Shui/Ink Storage Mechanism
The water/ink storage mechanism includes drip-type inking, cassette-type ink tube, piston inking, ink absorber, inking by bladder, drawbar inking, submarine inking, etc.
The dripping ink is directly stored in the pen tube behind the holding position. When refilling the ink, the holding position is turned on and the ink is injected into the pen tube directly with a dropper.
