2. Description of the Related Art As is well known, scissors are convenient tools that are frequently used in daily life, and many elaborately designed shapes are available. However, conventional scissors cannot be said to be sufficiently decorated with regard to their decoration. At best, paint the handle of the scissors or coat the handle with a colored synthetic resin material. It was about to decorate.

The inventor of the present invention has already developed a decorative technique for displaying a beautiful striped pattern on the surface of a metal material by using a cross-sectional striped pattern of a multi-layer clad steel formed by metallurgically stacking dissimilar metals. ing. Then, the present inventor got an idea of using this clad decoration technology for scissors decoration, but for the reasons described below, this clad decoration technology cannot be directly used for scissors. I did not go.

That is, scissors are generally used as shown in FIG.
A pair of scissors parts e and e each composed of a blade part a that performs a shearing action and a handle part b that extends rearward from the blade part are hingedly connected to each other so as to be rotatable. and in order to realize the durability, the inner surface a ₁ of the blade portion a of the scissor parts e of performing shearing action while forming a hard steel such as cutting steel, an outer surface a ₂ of the blade section a Kawakin Is made of soft steel to form a two-layer structure.

Accordingly, the outer surface of each scissor products e a (a ₂ and b _2), need only form a multi-layered clad steel instead of soft steel, like other cutlery, the outer surface (a ₂
And b ₂ ) can make the cladding cross-section stripe pattern appear relatively easily. However, the inner surface (a ₁
As for b ₁ ), as described above, it is necessary to use hard steel material to secure the sharpness of the scissors, and the cladding cross-section stripes are exposed on the inner surfaces (a ₁ and b ₁ ) as they are. Did not go to.

In order to enhance the decorativeness of the scissors, each scissor part e
There is no problem if only the cladding decoration on the outer side surfaces (a ₂ and b ₂ ) is sufficient. However, in the case of scissors, due to its structure, the inner surface b ₁ of the handle b of _one scissor part e is inevitable.
But since that would line up next to each other with the outer surface b ₂ of the handle portion b of the other scissor products e (see FIG. 1), only with the cladding decoration of the outer surface (a ₂ and b _2), the decorative Instead of halving it, it is better not to decorate at all. Thus, the decoration of the scissors is different from other knives such as kitchen knives and knives, and the cladding decoration technology could not be directly used for the scissors.

%, Fe balance).

The blade steel material 2 is arranged at the center of the upper surface of the clad steel material 10 and hot-rolled with its contact surface being welded and sealed, thereby metallurgically joining the blade steel material 2 and the clad steel material 10. Further, as shown in FIG. 4, the blade steel material 2 is partially divided by half at the blade steel material 2 portion to partially expose the blade steel material 2 on one side, and the laminated plate material 1 having a total thickness of 4.5 mm and a total width of 150 mm 1
Have gained. The blade steel 2 portion of the laminated plate 1 has a thickness of 1.5
mm x 65 mm wide.

In the present embodiment, the hot rolling process is performed in two steps in forming the laminated plate material 1 having the blade steel material 2 partially exposed on one side, but these two types of stainless steel materials are used. (SUS410, SUS310S) and the blade steel material 2 may be hot-rolled at once and metallurgically bonded to obtain the laminated plate material 1.

Next, the laminated plate material 1 obtained by hot rolling is subjected to punching to obtain a scissor part material E ₀ having a required shape composed of a blade part A and a handle part B (FIG. 5).
(See FIG. 7). At this time, the scissor part material E ₀ is punched so that the blade steel material 2 of the laminated plate material 1 is positioned on the blade part A of the scissor part material E ₀ (see FIG. 5), thereby obtaining the scissor part material E.
The inner surface A ₁ portion of the blade portion A of ₀ only is to expose the blade steel 2 (see FIGS. 6 and 7). Then, subjected to systemic-forging molding of scissor article a desired shape to the scissor parts Material E _0, remove the burr generated at this time (see FIGS. 8 and 9).

After that, the scissor part material E ₀ is subjected to a predetermined surface treatment so that a layered cross-section pattern of a dissimilar metal is exposed on the surface of the scissor part material E ₀ (see FIGS. 10 and 11). . That is, the inner surface A of the blade portion A where the blade steel material 2 is exposed.
₁ except for the outer surfaces (A ₂ and B ₂ ) of the blade A and the handle B of the scissor part material E ₀ and the inner surface B ₁ of the handle B. The surface of the two types of stainless steel material is formed by embossing to form desired irregularities on the surface (see FIG. 10), and smoothing the irregular surface to cut out the metal lamination cross section. (SUS410, SUS310S) to exhibit a variety of Damascus-like stripes that are varied (see FIG. 11).

Then, a required heat treatment is performed to obtain a pair of scissor parts EE, and the pair of scissor parts EE
If mutually pivotally hinged at an ordinary method, all surfaces except the inner surface A ₁ of the blade portion A of the blade steel 2 is exposed, cosmetic scissors layered stripes of the multi-layered clad steel was exposed Is completed (see FIG. 2).

Therefore, as shown in FIG. 2, the outer surface (A ₂
And B ₂ ), as well as the inner surface B ₁ of the handle B of the other scissor part E that is adjacent to the outer surfaces (A ₂ and B ₂ ). This makes it possible to expose the lamination cross-section stripe pattern, thereby improving the decorativeness of the scissors.

Moreover, the cross-sectional stripes are of course continuously exposed on the outer surfaces (A ₂ and B ₂ ) of the blade portion A and the handle portion B without being cut off. From the (A ₂ and B ₂ ) to the inner side surface B ₁ of the handle portion B on the back side, the scissors (not shown) also appear as a continuous pattern on the side surface, so that the entire scissors can be totally decorated. It is possible.

Further, in the makeup scissors according to the present invention,
Two stainless steel outer surface of the blade portion A and the shank B (A ₂ and B ₂₎ is metallurgically lamination (SUS410, SUS310
Since it is formed of S), it is possible to prevent the blade steel material 2 that performs shearing action by its laminating effect from warping or bending. Therefore, the initial sharpness of the scissors can be maintained for many years, and the durability of the scissors is greatly improved.

Although the embodiment which is a specific example of the present invention is generally configured as described above, the present invention is not limited to the above-described embodiment, and various modifications may be made within the description of the appended claims. Is possible.

For example, in the above embodiment, embossing for forming irregularities for producing a variety of cross-sectional stripes is performed.
Although subjected to whole-body forging molding is performed with respect to scissors product material E ₀ after removing the burr (see FIG. 10), not of course limited thereto, systemic-forging the unevenness forming It may be performed at the time of molding. This makes it possible to obtain the scissors component E that exhibits a relatively similar cross-sectional stripe pattern.

Further, the cross-sectional stripe pattern rich in this change may be previously exposed on the surface of the laminated board 1.
That is, similarly to the above-described scissors component material E ₀ , the plate surface of the laminated plate material 1 is locally embossed to form required irregularities on the plate surface. If the uneven surface is polished smoothly and the metal lamination cross section is cut out, it is possible to expose a variety of cross-sectional stripe patterns on the laminated plate 1. If so Thereafter further embossing against scissors product material E _0, it is possible to expose a cross section stripes richer in variation.

Further, the embossing for forming the unevenness may not be performed. The scissors product material E ₀ after removing the burr is subjected to whole-body forging molding, if so cut out as it is smooth polished to metal laminate section, to expose the linear parallel fringes relatively It becomes possible.
