If you have more than one fork, the outer one is your salad fork and the inner one is for your main dish. The fork for your main dish will be larger than your salad fork. We'll cover table settings in the last section. For right now, let's concentrate on how to hold your utensils and get to eating! The "right" way, of course. The index finger is mostly straight and rests near the base of the top, blunt side of the blade. The other four fingers wrap around the handle. While your index finger is resting on the top, your thumb juxtaposes it on the side. The end of the knife handle should be touching the base of your palm. This is the same in both styles. And both styles cater to right-handers. If you're left-handed, consider reversing pretty much anything you read on this topic. The tines (prongs) face away (downward) from you. The index finger is straight, and rests on the back-side near the head of the fork, but not so close you are in danger of touching the food. The other four fingers wrap around the handle. This is often referred to as the "hidden handle" method. This is because your hand is pretty much covering the entirety of the handle, secluding it from view. This makes the tip of the knife and fork also point towards the plate somewhat. Your elbows should be relaxed and not at all up in the air or uncomfortable. While we're at it, typically your elbows should be off the table at all times. But if you're taking a break from using your cutlery and in an informal setting, don't stress about it. In this style of eating, bring the fork to your mouth with the tines curving downward. The back of the fork will be up as you bring it to your mouth. Keep the fork in your left hand, even if you're right-handed. You may find that this method is the more efficient of the two if you experiment with both.

How would you rephrase that briefly using Vietnamese?
Nĩa luôn ở bên trái của đĩa và dao thì ở bên phải. Để cắt thức ăn trên đĩa thành miếng nhỏ, bạn cầm dao bằng tay phải. Cầm nĩa bằng tay trái. Cong cổ tay để ngón trỏ chỉ xuống dưới đĩa. Dùng nĩa lấy một mẫu thức ăn nhỏ cho vào miệng.
