Never down / Chopsticks

Chopsticks is Chinese’ main tableware. However the slender formation will pollute their heads when they are put on the table. “Never down” adds a crook (or bulge) on the traditional chopsticks and makes the tails of chopsticks heavier so that they can maintain uptilted not being polluted. Meanwhile the crook or bulge will make the stash easier by conciding the head and the tail.
