Description

発明の詳細な説明Detailed Description of the Invention

この発明は、刃物に関するものである。The present invention relates to a blade.

従来の積層材を利用した包丁等刃物は、刃先に強度を持たせたり波形の模様を出す為に、槌目といって昔から刀を作る時のように細かく金槌を使用し、職人の手で打っていた。近年もプレスにハンマーを取り付け連続的に打つ方法をとっていた。これらの方法では、積層材に均一な強度を出すために決まった箇所を打つ事は、熟練の職人にはできても、一般作業者の誰にでもできることではなかった。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.

また、従来のように槌やハンマーで打ち込まれた刃体部の場合、その積層材を研削し、研磨したとき積層材の表面に現れる模様が不規則で不明確に現れ、美的表現がしにくく、不均一な模様となり『霞』『槌目』のようにぼかした表現しかできなかった。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.

このように従来の積層材を利用した包丁等刃物は、強度を出すために、職人的な技術を必要とし、刃体部の表面模様には楽しく、綺麗で、作者の想いを伝える均一で解りやすい表現が出来なかったのである。
特開平７−８０１６３号公報 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.

この発明は、従来の積層材を利用した包丁等刃物において、刃物の強度と模様を出すために、職人的な技術を必要とし、均一な強度を出す事は、誰にでもできることではなかった。また、刃体部を研削したとき積層材の模様が不規則に現れ、美しさが表現しにくく不明確でぼかしたような形の表現しかできなかった。
そこで、熟練した職人の技術が無くても、誰にでも加工ができ、刃物として均一の強度を出し刃体部の表面模様にも楽しく、綺麗で、作者の想いを伝える形で表現が出来る刃物を提供することにある。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.

上記課題を達成するために、材質の異なる複数の積層材料を使用した積層材の刃物において、積層材の刃体部表面の決められた箇所に、花形など有形模様の型を使用してプレス加工で型押しを行い積層材料の層にズレを形成することで、均一な強度を出すとともに有形模様を明確に表現することにより解決する。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.

本発明は、前記のように構成され、従来の積層材を槌目といって昔から刀を作る時のように細かく金槌等で職人の手で打ったり、近年のようにプレスにハンマーを取り付け連続的に打つプレスハンマーの方法をとることなく、有形模様の型を使用してプレス加工により有形模様を形成することで刃体部に短時間で均一の強度を出せる効果がある。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.

また従来のように積層材を研削した場合の単純な縞模様や、槌目やハンマーで出来る不明確な模様ではなく、有形模様によって明確で解りやすく、楽しく、作者の想いを表す事ができ、積層材の材質の違った材料を組み合わせ積層する構造を上手く利用した綺麗で明確な模様を表現することが出来る効果がある。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.
