The present invention relates to a method for manufacturing a decorative knife that can form a beautiful cloud pattern on the surface of the knife.

い。
As is well known, conventionally used general-purpose knives include folding knives, in which the blade is folded into a sheath like a jacket knife.
There are two types of knives: a sheath knife, which has a blade part and a handle part made of a metal material, and a pointed knife. However, in the case of "folding knives" such as jacket knives, the outer surface of the sheath, which also serves as a handle, can be decorated, and as such a product form is approved on the market, there are only minor complaints. is not asked.

に加え、ハンドル部もブレード部も同色同模様に
なつて変化性に欠ける傾向があつた。 However, since the latter knife is made entirely of metal, a decorative handle made of natural wood, deer antler, ivory, etc. that can be used for gripping is attached to the handle. However, it has been pointed out that this increases the manufacturing cost and also has the disadvantage that dirt adheres to the mounting part of the decorative handle, making it unsightly. 'Flow'
If you apply this technique, you can create a ``disturbed pattern'' on the blade, and you can also use damascus steel.
By using steel, it is possible to create a damask pattern like a Damascus sword, but in either case, it is created by combining ferrous metals, hard steel and mild steel. As a result, not only the pattern formed is achromatic, but also the handle portion and the blade portion tend to have the same color and pattern, resulting in a lack of variability.

造することが可能になつたのである。 That is, in the present invention, in laminating and integrating a plurality of types of non-hardenable metal plates that do not harden even after being subjected to quenching temperature, on the upper and lower surfaces of the blade steel plate material 1', As the non-hardenable metal plate material to be used, layered plywood plates made by butting colored metal and achromatic metal are interposed in a hierarchical manner, and the laminated blade steel plate material 1' and the non-hardenable metal are interposed in a hierarchical manner. The plates are joined and integrated by the cladding method to obtain a laminated metal plate C having a blade steel layer 1, and then a knife prototype is cut out from this laminated metal plate, and the cut knife prototype is subjected to forging and grinding. After shaping into a knife shape having a handle part H and a blade part B, it is hardened and tempered, and then final finishing processes such as cutting edge processing and polishing are performed. A series of processes in which a chromatic cloud pattern appears on the surface of either the handle part H or the blade part B, and an achromatic cloud pattern appears on the remaining part by the turbostratic action caused by plastic deformation and the exposure action caused by grinding. By adopting this metal processing method, it became possible to efficiently manufacture a cutting knife with a cloud pattern with different colors on the handle and blade parts.

することは云うまでもない。 Although the method of this example is generally as described above, the present invention is by no means limited to the above-mentioned example, and various changes can be made within the scope of the claims. The combination of chromatic metals adopted in the method can be selected from various combinations depending on the user's preferences such as color tone and contrast. Naturally, it is possible to partially limit the handle (such as the end of the handle), and it is also possible to easily change the coloring by bringing it into contact with chemicals. It goes without saying that these also belong to the technical scope of the present invention.

After that, the handle part H is hardened and tempered, and then final finishing processes such as cutting and polishing are carried out. A method for producing a cutting knife having a cloud pattern, characterized in that a chromatic cloud pattern appears on the surface and an achromatic cloud pattern appears on the blade part B. 2. When stacking and integrating a plurality of types of non-hardenable metal plates, which do not harden even when subjected to quenching temperatures, on the upper and lower surfaces of the blade steel plate material 1' alternately, the laminated non-hardenable metal plates are As a hardened metal plate material, a butted plate material made by butting a colored metal and an achromatic metal is arranged hierarchically in every other layer, and these laminated blade steel plate materials 1' and a non-hardenable metal plate are rolled by a rolling method. A laminated metal plate C having a blade steel layer 1 is obtained by joining and integrating, and then, from this laminated metal plate, an achromatic cloud pattern forming area C 2 containing an achromatic metal layer matches the part where the handle portion is to be formed. After positioning and cutting the knife prototype, the die-cut knife prototype is subjected to forging and grinding to form a knife shape having a handle part H and a blade part B, and then quenched and tempered. By applying final finishing processes such as cutting and polishing, an achromatic cloud pattern is formed on the surface of the handle H due to the turbostratic action caused by plastic deformation and the exposure action caused by grinding. and a method for manufacturing a cutting knife having a cloud pattern, characterized in that a chromatic cloud pattern appears on the blade portion B.
