The nib is made of all kinds of animal hair. The key to quality lies in whether the front end of the hair tip has a sharp edge. Only a sharp blade can make a high-quality pen, and a pen without a sharp blade is inferior.
Twist the front edge of the pen tip by hand, pinch it flat, and then look at it in the sun or light. There is a relatively transparent and glittering part, that is, the nib, referred to as the leading edge.
If the leading edge of the leading edge area is 1.5 cm to 2 cm long, this is what calligraphers call a rhyme-length pen. There are long and short ones like this. The so-called long front pen of ancient calligraphers refers to the long front rather than the brush hair.
Extended data:
For example, the length of the nib can reach more than 10 cm, but it is made of hairless hair, without sharp edges, and the nib is very sharp. A sharp pen like this is what some calligraphy and painting friends call a "long-edged" pen. This is a pen cut with a blade instead of a pen tip.
Hair with sharp edges is naturally grown by animals, and it is impossible to make sharp edges by hand. The quality of raw materials is the basis to ensure the quality of brush. "One hair in a million" not only reflects the careful attitude of selecting materials, but also reflects the important role of selected raw materials in the quality of writing brushes.
Different kinds of brushes are made of different raw materials. The raw materials must be selected according to the varieties produced, and the details of each raw material, such as the length, color, thickness and straightness of the hair shaft, must be carefully selected to make a good brush stroke. In short, the quality of the brush is not based on the length of the brush, but the length of the front is the key.
