Abstract

To provide a tool that assists various types of grinding files with an angle and a tool including the tool.SOLUTION: A height part of 3 mm, 4 mm, or so, as an angle forming part of about 15 degrees which is optimum for grinding is attached to one side of a flat file b so that, not a handle but a grip c which is easy to apply force is attached to the rear surface of the file and grinding is performed. As a result, a burr is generated. However, by turning the file to remove the burr, high sharpness can be achieved.SELECTED DRAWING: Figure 1

Description

本発明は、包丁やナイフやはさみ等の刃物研ぎに関するものである。 The present invention relates to sharpening edge tools such as kitchen knives, knives and scissors.

刃物を昔ながらに砥石やダイヤモンド砥石やセラミック砥石等で研ぐ方法以外に、各種ヤスリ等を使用した研ぎ器はすでに販売されているが、砥石を固定し包丁を動かすのは、砥石が重いので包丁を動かすほうが、やりやすいからであり、海外では棒状の金属ヤスリと包丁を交差させて研ぐこともあるため、これを応用した器具として、Ｖ字型の隙間の底にヤスリを交差するように配し、包丁を差し込んで研ぐ方法や、柔軟性を持たせた研磨金属の一部を接触させて、その隙間を通して研ぐ器具等が市販されているが、研ぎ味が劣る難点があり、特徴としてこれらは包丁を動かす。 In addition to the traditional method of sharpening knives with whetstones, diamond whetstones, ceramic whetstones, etc., sharpeners using various types of files are already on the market. This is because it is easier to move it, and overseas, a bar-shaped metal file and kitchen knife are sometimes crossed to sharpen. , A method of sharpening by inserting a kitchen knife, and a tool that sharpens through a gap where a part of the polishing metal with flexibility is brought into contact with each other is commercially available, but there is a drawback that the sharpening taste is inferior, and these are characterized by move the knife.

日本刀の研ぎで、0.5ｍｍ程の薄さに裂いた砥石を1センチ角にして、漆で吉野紙を裏打ちした刃艶砥を親指で動かす研ぎは砥石が割れて指を傷つける危険があるが、ダイヤモンド加工等を施したヤスリに柄を付けて動かして研ぐ器具等は指を傷つける心配はないが砥石同様に角度を一定に保つことが難しい。 When sharpening a Japanese sword, the whetstone is cut into 0.5mm thin pieces, cut into 1cm squares, and the blade lined with Yoshino paper is lined with lacquer. , There is no fear of hurting fingers with instruments that sharpen by attaching a handle to a diamond-processed file, etc., but it is difficult to keep the angle constant like a whetstone.

砥石研ぎでは角度を保つのが難しいため、角度を保つ為の補助具はすでに市販されている。 Since it is difficult to keep the angle sharpened with whetstones, aids for keeping the angle are already on the market.

しかし各種研ぎ用ヤスリに角度を補助する器具やそれを有した器具はまだないので、出来れば難点は解消される。 However, since there is no tool for assisting the angle of various sharpening files or a tool with such a tool, the difficulty can be solved if possible.

解決しようとする問題点は、ヤスリや砥石を使用した研ぎは包丁の角度を一定に保つ技術が必要で、さらに砥石の場合は５分ほど水に浸す等の手間も必要だが、それらを必要としない市販の簡易研ぎ器は隙間に包丁を入れて動かし、研磨金属の間を通す場合も、共に、返しともバリとも呼ばれる金属片が出ないため、切れ味が劣るなど、それぞれに難点を抱えているが、本発明の方法だとそれらの難点を克服できる。 The problem to be solved is that sharpening using a file or whetstone requires a technique to keep the angle of the knife constant, and in the case of a whetstone, it takes time such as soaking it in water for about 5 minutes, but these are necessary. Simple sharpeners available on the market have their own drawbacks, such as being inferior in sharpness even when the knife is moved between the gaps and passed through the polished metal, because there are no metal fragments called barbs or burrs. However, the method of the present invention overcomes these difficulties.

本発明は、包丁研ぎに最適とされる１５度程の角度を平形ヤスリと包丁との間に出来るようにヤスリの一辺を３ミリか４ミリ前後、高くする事で実現できるが、それ以外に市販されている研ぎ用平形ヤスリは柄がついている形状なので研ぎ面に効率よく力を加えることが出来ないので、ヤスリの背面に取っ手を付ける形状に変えてやると力が加わりやすくなり、研ぎやすくなるので、研ぐと出てくる返しともバリとも言われる金属片が出てくるので、これを裏返してなくすることで鋭い切れ味とする事に成功した。 The present invention can be realized by raising one side of the file by about 3 mm or 4 mm so that an angle of about 15 degrees, which is considered optimal for sharpening knives, can be created between the flat file and the knife. The flat file for sharpening on the market has a handle, so it is not possible to efficiently apply force to the sharpening surface. Therefore, when sharpened, metal pieces called burrs come out.

本発明の研ぎ器は小型軽量で包丁以外にナイフやはさみ等も研ぐことが出来て、従来の設置型研ぎ器では出来なかったバリだしとバリ取りが出来るようになったので研ぎ味が格段に向上した。 The sharpener of the present invention is compact and lightweight, and can sharpen knives, scissors, etc. in addition to kitchen knives. Improved.

包丁やはさみを台に置くか、手で持つなどして本発明器具の平形ヤスリが研ぎに最適な１５度程を形成してくれるので上下左右方向に動かして研ぐと、返しともバリとも言われる金属片が裏側に出てくるので、裏返しして軽く研ぐことでバリを取り、鋭い切れ味になった。 Place the knife or scissors on the table or hold it in your hand, and the flat file of the tool of the present invention will form an optimum angle of about 15 degrees for sharpening. Since the metal piece comes out on the back side, I turned it inside out and sharpened it lightly to remove the burrs and made it sharp.

Claims

Attach a member with a height of about 3 mm or 4 mm to the outside of one side of the file to create a certain angle, and attach the handle to the back of the file instead of the handle. The size can be larger or smaller than 5 cm long and 2 cm wide and 1 mm thick.
