1829, the British james bailey successfully developed the nib. After special treatment, it is smooth and elastic, and it is very smooth to write, which is deeply loved by people. But this pen needs to be dipped in ink to write, which is very troublesome.
1884, wortmann, an employee of an insurance company in the United States, accidentally spilled the ink in the quill pen when signing the contract, which stained the contract. Just as he was about to sign a new contract, a competitor stole his business. This greatly stimulated him, and he decided to invent a pen that can control ink and write fluently.
Later, referring to the principle that tree roots can transport nutrients to branches and leaves, a pen with capillary for ink supply was invented. The pen end of this pen can be disassembled and ink is injected through a small dropper, which is the earliest pen.
Extended data:
Generally speaking, the nib is the most critical part of the pen, with different thicknesses. Generally speaking, the most common pen tip sizes are "B (wide), M (medium), FM (thin-medium), F (thin) and EF (extra thin)".
From coarse to fine, it is B > M>F & gtEF, and there will be some differences in the specifications of each pen manufacturer. Under the same size unit, the Japanese pen will be thinner than the European pen.
According to the usual writing habits, westerners usually use the M-tip as the main pen and choose the B-tip when signing. Due to the complexity of Chinese writing strokes, F or thinner EF pen tips can generally be used.
