Hold the knife in your right hand.
When eating Western food, it is normal to hold the knife in the right hand and the fork in the left hand, which helps to complete the cutting and serving of food more smoothly and safely. Holding the knife in the right hand is what most people are used to operating with their right hand, which allows them to control the strength and direction of the knife more naturally and accurately. The fork held in the left hand is used to fix the food and bring the cut food into the mouth.
If you are left-handed, you can choose to hold the knife in your left hand and the fork in your right hand, which will be more consistent with your usage habits. In general, when eating Western food, you should choose a way that you are accustomed to and comfortable with to ensure a smooth meal.
