Abstract

PROBLEM TO BE SOLVED: To provide a knife, safe, easy to remove dirt or small, and never corroded with a solvent (organic) by forming an undercoat layer on a knife material by use of a nontoxic inorganic aqueous ceramic paint, forming a topcoat layer by use of a paint, and forming a blade part on the coated knife material. SOLUTION: As the material of the knife, a material of stainless, iron, steel, or titanium is used, and this knife material is subjected to a working processing (for example, surface treatment) to form various patterns or finish the surface. For example, the surface is treated with hydrofluoric acid or oxalic acid to provide a colored surface. Otherwise, the surface is treated by buffing or sand blasting to provide a pattern such as polka dot, scale, irregularity, satin finish or spot, or be pattern-less. An undercoat layer 2 is formed on such a surface of the knife material by use of a nontoxic inorganic aqueous ceramic coating material, and a topcoat layer 3 is formed by use of a paint and/or a coating material such as pigment. Thereafter, a blade part A1 is formed on this coated knife material 1c to complete a knife A.

Therefore, it is possible to manufacture a cutting tool coated with a high-quality non-toxic inorganic paint under optimum conditions.

According to a seventh aspect of the present invention, the preheating is performed at room temperature to about 100 ° C.
℃, intermediate heating is normal temperature ~ about 100 ℃, main drying is about 50 ℃ ~
It is configured at approximately 300 ° C. Therefore, temperature control such as a heat treatment temperature can be reliably and promptly performed .
