A knife is a sharp tool that is used to cut or chop things. It has a handle and a blade that is very sharp. You can use a knife to cut fruits, vegetables, meat or bread. You may also need a knife to open packages or cut through materials like paper or plastic. It is important to use a knife carefully, holding it by the handle and away from the sharp blade. Knives can be dangerous and should be used responsibly.
