Types of nib standards: usually including thin, medium and wide. Many companies have more choices. The choice can range from the size of the needle tip to the shape of a shovel with a width of three times. Generally speaking, yes; People with light hands or small handwriting choose a thin nib. Write with thick hands, choose wide ones, not sharp ones. However, the choice of nib still depends on your preference. However, the ultra-fine nib is generally only suitable for digital works, not for ordinary writing. Italic tip: The inclined nib has a sharp horizontal edge, which is different from the standard spherical shape. So the lines of the words are thicker at the vertical pen. The width of the italic pen tip varies greatly. The wider the pen tip, the more obvious the difference between stroke thickness. The horizontal edge of the italic pen tip is easy to scrape paper, so pay more attention when writing. When writing, the italic pen tip should make a 45-degree angle with the paper to prevent the font from being written as a square. Italic: the tangent line on the left side of the oblique pen tip forms an angle of 15 degrees, which is suitable for many people with a certain angle when holding the pen. Holding the pen like that will put more pressure on one side of the pen tip, resulting in irregular ink flow. Oblique nib also has various models from thin to thick to choose from, and the stroke thickness of oblique nib is not as exaggerated as that of oblique nib. Anti-oblique type: the shape of anti-oblique nib is just the opposite of oblique nib, which is generally used by left-handed writers. Oblique graphics: This pen is suitable for people who want to master the general principles of italic writing, but don't want to work too hard. With this pen tip, you can follow the italic style more casually and write more beautiful words. There are usually two kinds of oblique and italic pens: one is 15 degree pen tip, which is suitable for right-handed people to write, and the other is 30 degree pen tip, which is suitable for left-handed people to write. Material of nib: The nib of a good pen is usually made of gold. Generally, it is 12K and 14K, but there are also 18K gold. Because gold is too soft, a small ball made of iridium or ruthenium will be welded on the tip of the pen, and the ball will form a perfect writing surface after polishing. The hardness of the nib is controlled by the thickness and length of the nib, which is generally different from each manufacturer. On cheap pens, the nib is usually made of stainless steel or other gold-plated metal. Although its life is not as long as a gold nib, it is very easy to use. But each manufacturer's technology is different, so if you want to find your favorite pen tip, you must try more pens from several manufacturers. Tip size: General pen manufacturers will mark the size and type of the tip on the tip. Generally, EF, f, m, b and BB are marked with standard pen tips. If the mark is OM, OB, OBB, it is oblique. There are five common pen tip sizes. From fine to coarse, EF = XF = ultra-fine nib width: 0.24mm ~ 0.28mmF = fine nib width: 0.28mm ~ 0.34mmM = medium nib width: 0.34mm ~ 0.44mmB = wide nib width: 0.44 mm ~ 0.54 mmbb = double width bb. About: 0.66mm~0.86mm Some manufacturers have more subdivided nib, such as EEF thinner than EF, 3B thicker than BB, and MF nib between F and M. Although different brands have different definitions of nib size (that is, M nib of M brand may be thicker or thinner than P brand), the width of nib is mostly between 0. 18 mm and 0.86mm, and some manufacturers want to meet personal needs. There will be an inclined nib, for example: OM = Oblique center OBB = Oblique width OBB = Oblique double width A good nib is the soul of a good pen, so it is very important to choose a good nib. Basically, the nib of F is enough for daily Chinese writing. If you like to write bigger words, you can use m-tip. B and BB are too big for ordinary Chinese writing, so they are more suitable for signature. Generally speaking, there is no need for oblique tips in daily Chinese writing. If you are a friend who practices calligraphy, you can try the oblique tip, which may have a different effect. Also, generally speaking, the nib of Japanese manufacturers is thinner than that of Europe and America. So friends who like to write fine print can buy products of Japanese brands. There is also the water output of the pen, which is also an important factor to control the stroke size. Pens with large water output generally have thick lines. Everyone has different preferences about the elasticity of the pen tip. Just try more when you buy a pen.
