PURPOSE: A knife sharpener is provided to sharpen a knife with the rough roughness by mounting grinding pieces of different materials, to consecutively sharpen it with fine roughness, and to record messages or to deliver the messages to the other people by inserting a memo paper. CONSTITUTION: A knife sharpener comprises a main body (120), a cover, an adsorbing plate, and a handle (150). Tungsten grinding pieces are positioned on the upper surface of the main body and ceramic grinding pieces (110S) are positioned on the rear of the tungsten grinding pieces. A cushioning unit supporting the grinding pieces is positioned below the grinding pieces. A supporter (121) supporting each grinding piece is formed in the main body in order for each grinding piece to be positioned by being standing. The adsorbing plate is fixed or loosened on a wall or bottom as the handle rotates. A part of the tungsten grinding pieces and the ceramic grinding pieces are overlapped in a lateral direction and the overlapped part forms the internal angle. |
