Eat a piece of steak and cut it. Hold a knife in your right hand and a fork in your left. The steak should be cut from the outside to the inside. If you don't cut it once, cut it again. You can't cut it by sawing or pulling it.

Cut the meat in a moderate size, and don't put large pieces into your mouth. Pork chops and mutton should be well done and eaten in the same way as steak. Fried chicken or roast chicken, eaten with a knife and fork on formal occasions. When eating meat, close your lips and don't make any noise.

Don't send the food into your mouth before you swallow it. Don't cut the meat into pieces first (this is English, American can cut it first), which is not only indecent, but also a pity that the gravy is lost.

Extended data:

When eating with a knife and fork, take the knife and fork from the outside to the inside, hold the fork in your left hand and hold the knife in your right hand; When cutting things, hold the fork in your left hand and hold the food, hold the knife in your right hand and saw it into small pieces, and then send it to your mouth with a fork. When using a knife, the blade should not be outward. When you put down your knife and fork during a meal, you should put them in a figure of eight and put them on the edge of the plate respectively.

The blade is facing itself, indicating that you will continue to eat. After each dish, put the knife and fork together on the plate. If you are talking, you can hold a knife and fork without putting it down. You can also hold the fork with your right hand when you don't use a knife.

However, if you need to make gestures, you should put down your knife and fork. Never wave and shake your knife and fork in the air with one hand, nor wipe your mouth with a napkin with the other hand, nor take a glass with one hand and a fork with the other. Remember, never put one end of the knife and fork on the plate and the other end on the table.
