Abstract

<P>PROBLEM TO BE SOLVED: To provide a knife which can be worked by anyone without requiring craftsmanship, and has a uniform strength on the blade part and is provided with an interesting and beautiful pattern expressing the concept of a manufacturer. <P>SOLUTION: The knife is made of a laminate consisting of a plurality of different laminating materials 4, and a predetermined section on the surface of the knife made of the laminate is embossed with a die having a pattern such as a flower pattern by press-working to cause slips in the layers of the laminating materials, and thus, the knife is provided with a uniform strength, and the pattern 2 is clearly expressed by grinding the knife. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

Detailed Description of the Invention

The present invention relates to a blade.

Knives such as knives using conventional laminated materials are finely crafted by craftsmen as if they were making swords from a long time ago, in order to give strength to the cutting edges and create corrugated patterns. I was striking. In recent years, a method has been adopted in which a hammer is attached to the press and is continuously hit. In these methods, it was not possible for a general worker to do it, even for a skilled craftsman, to hit a fixed point in order to give the laminate a uniform strength.

Also, in the case of a blade body that has been driven with a scissors or hammer as in the past, when the laminated material is ground and polished, the pattern that appears on the surface of the laminated material appears irregularly and unclearly, and it is difficult to make an aesthetic expression The result was a non-uniform pattern, and only a blurred expression such as “霞” and “槌” was possible.

In this way, knives such as knives using conventional laminated materials require craftsmanship to give strength, and the surface pattern of the blade body is fun, beautiful, and uniform and conveys the thoughts of the author. I couldn't make easy expressions.

The present invention requires a craftsmany technique in order to bring out the strength and pattern of a knife in a knife such as a kitchen knife using a conventional laminated material, and it has not been possible for anyone to produce a uniform strength. In addition, when the blade part was ground, the pattern of the laminated material appeared irregularly, and it was difficult to express beauty, and it was only possible to express an unclear and blurred shape.
Therefore, even if there is no skill of skilled craftsmen, anyone can process it, and it has a uniform strength as a knife, and the surface pattern of the blade body part is fun, beautiful, and can be expressed in a form that conveys the author's feelings Is to provide.

In order to achieve the above-mentioned problem, in a laminated blade using a plurality of laminated materials of different materials, press processing is performed using a tangible pattern die such as a flower shape at a predetermined position on the blade body surface of the laminated material. The problem is solved by expressing the tangible pattern while giving uniform strength by embossing and forming a gap in the layer of the laminated material.

The present invention is configured as described above, and the conventional laminated material is called a grid, and it is finely struck by a craftsman with a hammer as in the case of making a sword from the old days, or a hammer is attached to a press as in recent years There is an effect that uniform strength can be obtained in a short time in the blade body part by forming a tangible pattern by press working using a tangible pattern die without using the method of a press hammer continuously.

In addition, it is not a simple stripe pattern when grinding laminated materials as in the past, or an unclear pattern that can be done with a grid or hammer, but it is clear and easy to understand with a tangible pattern, and it can express the author's feelings, There is an effect that it is possible to express a beautiful and clear pattern by making good use of a structure in which layers of different materials are combined and laminated.

BEST MODE FOR CARRYING OUT THE INVENTION

FIG. 1 is a view showing a cutting tool of the present invention, and shows a state in which a tangible pattern 2 is arranged along a cutting edge portion of a blade body portion 1. Since the tangible pattern 2 is arranged along the cutting edge and pressed by a press die, it is uniform with the effect that a skilled craftsman strikes the laminated materials 4, 5 and 6 along the cutting edge. It can give strength.

FIG. 2 is a partial cross-sectional view and a perspective view of the tangible pattern 2 of FIG. 1. By pressing the laminated materials 4, 5, 6 of different materials, the misalignment 12 of the laminated material can be made. It shows that the flower-shaped tangible pattern 2 is expressed on the surface of which is diagonally ground. By pressing the laminated material 10, the laminated materials 4, 5, 6 can be compressed and the laminated material misaligned 12, and the strength of the laminated material 10 can be increased, and a beautiful flower-shaped striped pattern can be expressed as the tangible pattern 2. is there.

Hereinafter, the formation procedure will be described with reference to FIGS.
FIG. 3 shows an organic pattern press-shaped convex portion 8, which is pressed by pressing to form a press-formed concave portion 7, and the laminated materials 5 and 6 having different qualities constituting the laminated material 10 cause the laminated material shift 12. A cross section formed by compression is shown. In this figure, the number of laminated materials 5 and 6 is omitted.

FIG. 4 is a diagram of FIG. 3 viewed from an oblique direction.

FIG. 5 is a cross-sectional view showing the state of the laminated materials 4, 5, 6 and the tangible pattern 2 when the ground portions 11 a, 11 b on both sides of the laminated material 10 are ground into a blade shape. Lamination materials 12 are formed in the lamination materials 5 and 6.

FIG. 6 shows a state in which the tangible pattern 2 is arranged in the center of the blade body portion in another embodiment of the present invention. The arrangement of the tangible pattern 2 can be appropriately arranged according to the blade.

In the present invention, press working refers to reflection, hand press, power press, forging, and the like.

The knife in the technical field of the present invention includes a kitchen knife, a kitchen knife, a pocket knife, a mountain knife, an underwater knife, a fruit knife, a cutout, a carving sword, a thorn, a sickle, scissors, an electric knife, a yachtman knife, a diver Knives, eating knives, butter knives, pizza cutters, cheese knives, manicure knives, sharpening knives, seal detaching knives, pallet knives, painting knives, paper knives, surgical knives hunting knives, pencil sharpener knives, saws Etc.

In the present embodiment, the tangible pattern 2 is provided on one side of the blade, but may be provided on both sides.

The tangible pattern 2 in the present invention is a tangible pattern that exists in nature, such as a mountain, a bird, a fish, an animal, a tree, a flowering tree, a river, a star, the sun, the moon, a flower, etc. Things such as buildings, towers, bridges, automobiles, trains, trains, airplanes, and characters such as marks, numbers, alphabets, and kanji.

It is a general view which shows the kitchen knife of this invention. The fragmentary figure showing the cross section and surface of this invention is shown. The partial cross section of the processing state of this invention, and a perspective view are shown. The perspective view which shows the processing state of this invention is shown. The partial cross section when the knife of this invention is ground is shown. Another embodiment of the present invention will be described.
