Title: Knife
Inventor: LEE JI U
IPC: A47G21/06
Filed: 2019-11-13
Abstract: The present invention relates to kitchen utensils, and in particular, to an assembly-type fruit knife in which a fork and a knife sharpener are coupled. In the conventional art, an all-in-one fruit knife is provided, but is only used for cutting food. After food is cut using a fruit knife, a fork and a sharpener are provided to be used separately. When kitchen utensils are washed, to cut a piece of fruit, a sharpener, a fork, and even a knife are washed one by one. The purpose of the present invention is to provide a fork and a knife sharpener even with only a single knife. The present invention relates to a fruit knife changed to a fork by sharpening a knife when a blade is separated and inserted upside down. In the conventional art, a fork and a sharpener are not coupled to one object in a fruit knife, so it is difficult to sharpen a knife quickly and easily and to eat food immediately after cutting the food. To resolve the difficulty, a blade and a fork are integrated and a sharpener is attached to an entrance of a handle into which a knife is inserted. In a conventional fruit knife, a fork and a blade are provided back and forth. In accordance with the present invention, a fork and a blade are detachably attached to a knife handle back and forth. In the process of attaching and detaching a knife, the knife could be sharpened through a knife sharpener attached to the entrance of the handle. Thus, food can be cooked and consumed more easily and quickly with a knife.
