I think the issue will be that not all pincers (and other similar kitchen utensils) are not all made the same. Some are much harder to squeeze than others. Some don't open as wide, so I may not be able to get it around a large chunk of sushi. With chopsticks I have neither of these problems (although chopsticks do vary in other ways).
