I eat sushi with chopsticks, Kentucky Fried Chicken with sporks, and everything else I use a fork. Knife or spoon only if needed like for cutting meat or eating soup.
I prefer to cut any thing that needs to be cut first, so I can just eat it without having to stop and cut it. I feel like it’ll stay warm longer that way. I may be wrong. I eat anything I can with a spoon. If it can’t be eaten with a spoon, I use a fork.
