First, the types of brushes
There are three common brushes: wolf hair, wool and double brushes.
Wolf hair: a pen made of the hair on the tail of a weasel is very elastic.
Sheep hair: the pen made of goat hair is not as elastic as wolf hair.
Double-strand brush: a pen made of more than two kinds of wool, the most common of which is double-strand brush for wolves and sheep. It is moderate in hardness and is suitable for beginners.
Second, the choice of brush
The predecessors summarized the basic standards of a good pen as "four virtues", namely: sharp, round, neat and healthy.
Sharp: when the pens are together, the two ends should be sharp so that the strokes can be written.
Round: refers to the perfect shape of jujube pit, which looks full of hair, while the pen tip is flat and thin, lacking pen power.
When it is completely opened, the writing brush in the shape of jujube pit is the best.
Qi: After writing, the length of the brush should be consistent inside and outside. The test method is: flatten the pen with your fingers to make the nib as flat as an oil painting pen. At this time, you can clearly see whether the length of bristles is consistent. A good pen should be even and even. When writing, Qi Xin works together, the strokes are complete, and he writes freely. Poor brush hair is often uneven, and when writing, the brush is often exposed outside the strokes at the turning point or the front end. The ancients called it "thief hair"
Health: The pen should be flexible and firm. Press the pen and it will unfold; When the pen is lifted, it naturally returns to the condensed state. Inferior pens can't get together after being pressed, which means that they are hairy and unhealthy.
It is recommended for beginners to use a double-headed brush with a nib less than 4cm and a nib diameter of about 1cm.
In fact, the definition of good pen depends on the user's own experience. If you think your writing brush is very comfortable, it is actually a good pen!
