In fact, ancient fishhooks were also made of barbs, because it was not high-tech. Iron will become very tough as long as it is heated and forged repeatedly. Then the iron is forged into a thin iron sheet, and then heated to a certain temperature, the iron will become very soft. At this time, the iron sheet can be cut into filaments with tools, and the iron sheet can be rubbed several times, and the iron wire will become a needle blank. Grinding the needle blank at one end, slightly flattening the other end, and then heating and quenching. If one end of the needle blank is sharpened and engraved with barbs, it is a fishhook. From the embroidery needle used in ancient times, we can imagine what the fishhook was like at that time. The embroidery needle will never be rough and heavy, otherwise what do you think of the embroidered clothes? There were a lot of skilled craftsmen in ancient times, and people in the past were willing to work hard, so the ancient fishhooks were by no means worse than now.
