The sleeve 4 for the pocket 4 is buried in the notched pocket 3a, and the sharpener body 5 is housed in the sleeve 4 for the pocket so as to be inserted and removed exposing the finger hooking part 5c for attachment and detachment on both side faces. for a kitchen knife blade body 2, super hard ceramics or tungsten carbide whose HV value is ≥1,000 is used. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

本発明は、ダイヤモンドシャープナ付き包丁に関するものであり、更に詳細には、汎用されている砥石では砥ぐことのできないＨＶ（ヴッカース）値１０００以上の超硬度の刃先を有するダイヤモンドシャープナ付き包丁に関するものである。   The present invention relates to a knife with a diamond sharpener, and more particularly, to a knife with a diamond sharpener having a cutting edge with an HV (Vuckers) value of 1000 or higher that cannot be ground with a general-purpose grindstone. Is.

従来、包丁は一般家庭、飲食店等において汎用されており、その種類や材質も多岐にわたって開発されて使用されており、夫々の生活や仕事に役立っている。   Conventionally, kitchen knives have been widely used in general households, restaurants, etc., and their types and materials have been developed and used in a wide variety of ways, and are useful for their lives and work.

然し乍ら、一般的な鉄製やステンレス製の包丁は硬度が比較的低く経時の使用により刃先の鋭利性が低下してしまう為、天然砥石や人工砥石を用いて砥いで鋭利性を復活させているが、刃先を超硬度の素材で形成することにより鋭利性が長期にわたり維持できるため、セラミックのような超硬度の素材で形成したものもあるが、鋭利性が失われた時に、一般の天然砥石や人工砥石では砥げないので専用砥石を必要とするために、メーカーや専門業者に依頼して砥いでいる実情であり、また、包丁の購入時に添付されていても頻繁に用いるものでないので紛失や所在が解らなくなることがある。   However, general iron and stainless steel knives are relatively low in hardness, and the sharpness of the cutting edge decreases with time, so the sharpness is restored by grinding with a natural or artificial grindstone. , Because the sharpness can be maintained for a long time by forming the cutting edge with a super-hard material, there are some made with a super-hard material such as ceramic, but when the sharpness is lost, Since it is not possible to grind with an artificial grindstone, it requires the use of a dedicated grindstone, so it is the actual situation of grinding by requesting a manufacturer or specialist, and even if it is attached at the time of purchasing a knife, it is not frequently used, so it is lost or Whereabouts may not be understood.

例えば、先に開示された、側面視において、円弧状先端稜辺７を有する刃部３の背面稜辺５に直線部分５ａを備えており、円弧状先端稜辺は、その接線が前記背面稜辺の直線部分の延長線と４５°の角度で交叉する基準点を有するとともに、該基準点を中心として前記接線に沿って３ｍｍの範囲の前記円弧状先端稜辺の曲率半径が２〜６ｍｍであり、且つ、前記基準点を中心として前記接線に沿って３ｍｍの範囲の前記円弧状先端稜辺のうち、すくなくとも基準点までに前記切刃稜辺に連続して刃付けが施されているもの（特許文献１参照）や、柄部と、柄部に取り付けられたセラミック製の刃部とからなり、刃部は、切刃稜辺と、切刃稜辺と互いに背面の関係にある背面稜辺と、刃部の先端部に設けられ切刃稜辺に連続し所定の曲率半径を有する円弧状先端稜辺とを有するセラミック製刃物であり、刃部の少なくとも一側面は、背面稜辺から切刃稜辺へ向かって傾斜した大刃面と、大刃面から切刃稜辺にわたって大刃面よりも大きな角度で傾斜した小刃面とからなり、小刃面は少なくとも切刃稜辺から円弧状先端稜辺を通って稜辺の円弧が終了する位置にかけて形成されているもの（特許文献２参照）カッター本体に組み込まれているスリーブ部分の先端に、研磨剤及び砥石を付けることにより、使用時の刃の出し入れによって刃を研磨する。従って、常に刃の切れ味が良い状態を保つことが可能になる。また、本体後部に付いている、従来の刃を折るための付属品に、研磨剤及び砥石を組み込まれた溝を作ることにより、この５の部分を刃に直接あてて、さらに研磨することが出来、刃の寿命を長持ちさせるので、経済的に役立つもの（特許文献３参照）や、刃体１と、この刃体１を支持する柄２と、この柄２に着脱自在な砥石３と、を備えた刃物Ｘであって、柄２の外面のうち、刃体１の厚み方向に間隔を隔てた一対の側面２１ａ，２１ｂの少なくとも一方の全体または一部は、刃体１の厚み方向中心線Ｌに対して傾斜した平面状の傾斜面とされており、砥石３を用いて刃体１の刃先部１３を研ぐときには、上記傾斜面が所望の台５の表面５１に接触するように柄２を台５上に載置することによって刃体１がその刀背１４から刃先１５に向かうにつれて上方に変位する斜めの姿勢に設定可能とされているもの（特許文献４参照）や、が開示されている。
