If there are three kinds of knives with different specifications at the same time when eating, the correct usage is generally: the one with small serrations is used to cut meat and make food. Medium-sized ones are used to cut large pieces of vegetables into small pieces. And that kind of small knife with a round tip and some upturned top is used to cut the bun, and then use it to pick some jam and cream to spread on it.
Hold the fork in your left hand, and move gently when you fork up the food and send it to your mouth. Pick up a proper amount of food and put it in your mouth at one time. When picking up food in your mouth, your teeth only touch the food. Don't bite the fork, and don't let the knife and fork sound on your teeth or plate.
The direction and position of knife and fork are exquisite:
The knife and fork are placed on the saucer in a figure of eight, with the knife edge facing inward and the fork tip facing downward, which means that you will continue to eat. Knife and fork are placed in parallel on the saucer, and the knife edge is outward, and the fork tip is upward, which means you don't eat. The spoon is placed horizontally in the soup plate with the spoon center up, which also means that the soup tableware can be taken away.
Never put a used knife, fork or spoon on the table, because this is an incorrect posture and it is easy to stain the tablecloth.
