Who invented scissors?

Can Leonardo da Vinci invent scissors more than 500 years ago? This is a cold joke. If he invented scissors, the clothes worn by ancient China people would not be made of anything. Did they tear it out by hand or cut it with a knife? If we can tear it out by hand, I think our predecessors will be immortals. Leonardo da Vinci only improved scissors and registered a patent. If the patent was used in ancient times, it is impossible to say that Leonardo da Vinci invented scissors. Scissors have become an indispensable tool in people's daily production and life. Tailors should cut cloth and thread, village women should cut paper and cut metal skin, herders should cut wool, gardeners should cut branches and coppersmith should cut scissors. Although they are not amazing in appearance, they are widely used. When tools such as knives and shovels can't exert force, shearing can be easily solved. So how were scissors invented? When was it invented? Who invented it? Some people have collected some real objects of ancient knives and scissors, which are very rare and have great research value. For discussion and analysis, it may be instructive to solve the mystery of the invention of scissors. One is a bronze sword of the Warring States period, with a length of 10 cm and a width of 1 cm, and the thickest part of the back is 0.3cm.. There is a double-layer oval ring at the end of the handle, which is used for hand kneading. The gap between the two layers is only half a millimeter, which is extremely ingenious. The copper rust on it is a natural emerald green, which can't be peeled off by hand. This knife was used by the ancients to cut, cut, cut and cut. But it is not convenient to cut soft things such as cotton, silk and silk. So in practice, the ancients used two knives to cut each other, so the silk was easy to break. This is the origin of the action of "cutting", and the prototype of scissors is formed in this way. The pictographic meaning of the Chinese character "Jian" means "There is a knife in front of the knife". Scissors, as daily necessities, have a long history in China. This can be learned from the poem "Singing Willow" by the poet He in the Tang Dynasty, "I don't know who cut the thin leaves, but it looks like scissors in February". The folk paper-cutting art with a long history also proves the long history of scissors in China. The pictographic meaning of the Chinese character "Jian" means "There is a knife in front of the knife". The ancients called scissors "dragon sword", which shows its importance in life. The earliest existing scissors in China were found in Luoyang. Recently, I had the opportunity to visit the famous tomb museum in Luoyang again, where I saw this pair of scissors unearthed from the tomb of the Western Han Dynasty, which has been more than 2 100 years. This rusty bronze scissors of the Western Han Dynasty, about 20 cm long, has a different appearance from modern scissors. There is no shaft eye and supporting shaft in the middle, but the two ends of an iron bar are tempered into a knife shape to grind a sharp blade, and then the iron bar is bent into an "S" shape to make the blades at both ends correspond. Therefore, the scissors are naturally opened when not in use; When in use, people can cut things by pressing the blades at both ends. As soon as you let go, scissors will return to their original state by the elasticity of wrought iron, just like modern people use tweezers. Modern scissors have greatly improved in shape, material, technology, quality, variety and function compared with ancient scissors. However, judging from the existing relics, the scissors used by people in the Song Dynasty are generally close to modern appearance. Luoyang Tomb Museum also has a pair of scissors unearthed in the tomb of Xining in the Northern Song Dynasty (AD 1072), which looks very similar to modern scissors. This shows that China's scissors model has been used for at least 1000 years.
