Personally, I think the best material for chopsticks is alloy chopsticks (I remember that the packaging is a mixture of aluminum alloy and glass fiber, and the specific formula is unknown). I bought 10 in the supermarket, and later found that there are two pieces of 10/5 on the Internet ... I wonder 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 they will never be deformed. Chopsticks are bound to deform when used for a long time, and deformed chopsticks are very uncomfortable to hold things. Metal chopsticks may be barely straightened by hand, while bamboo chopsticks often need to be discarded. As a person who doesn't like to change daily necessities, I hope that everything I can't see is full of quality and can be used for a long time. I like to choose this kind of chopsticks very much.
