Personally, I think the best material for chopsticks is alloy chopsticks (I remember that the package says that aluminum alloy and glass fiber are mixed, and I don't know the detailed formula). I bought them at 11 yuan a pair in the supermarket, and later I found that there are 15 pieces of 11 pairs online ... I don't know if there is any difference in quality between them. Compared with chopsticks made of plastic, wood, silver, steel, bamboo and other conventional materials, the biggest advantage of this kind of chopsticks is that it will never deform. Chopsticks that have been used for a long time are bound to deform, and the deformed chopsticks are very uncomfortable to hold things. Metal chopsticks may be able to be barely straightened by hand, while bamboo and wood chopsticks often need to be discarded. As a person who doesn't like to change daily necessities, I hope that everything I don't see is full of quality and can be used for a long time. I like to choose this kind of chopsticks very much.
