The knife was a very important weapon in ancient times, and it was indispensable for marching and fighting. After entering the era of hot weapons, the knife gradually came out of people’s field of vision, but as long as it is mentioned, the word “danger” will still appear. In addition to being a weapon, knives have many other applications. Kitchen knives can be used to cut vegetables; small knives can be used to sharpen pencils and paper; Swiss army knives can help outdoor enthusiasts to survive in the wild. The material for making knives is mainly steel. Since the emergence of carbon fiber, people have begun to try to make knives with it.Carbon fiber knives have many advantages compared with ordinary knives:1. Light weight. Since traditional knives are made of metal materials, they are heavy, and smaller ones are fine. Large ones are inconvenient to carry and operate. It will be easier to use after the weight is reduced.2. High strength and high toughness. We often use knives to cut objects. The strength and toughness of steel is good, but it is still not as good as carbon fiber. The strength of carbon fiber is several times that of steel, and the toughness of fiber is very strong.3. The high temperature resistance, low temperature resistance, corrosion resistance and impact resistance of carbon fiber are very good. In terms of kitchen knife. Sometimes the cut vegetables are taken out of the refrigerator right away. The temperature is very low, which may affect the kitchen knife. Moreover, the kitchen knife has to be in contact with different substances frequently, and various juices will corrode it. , So carbon fiber is very advantageous in performance.4. From the appearance point of view, carbon fiber knives are fashionable and suitable for all ages.There are not many carbon fiber knives on the market, but those who have used them say that they are good, and they are not inferior to metal knives. There are many carbon fiber products on the market. Violins, spectacle frames, chairs, desk lamps, etc. can all be made of carbon fiber. It covers a wide range of fields and will continue to expand in the future.
