【考案の詳細な説明】
〔産業上の利用分野〕
本考案は、強靱性に富み、而かも切れ味良好な
庖丁に係るものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a knife that is highly tough and sharp.
最近、テレビの料理番組の影響により素人でも
牛刀庖丁を使用するようになつた。
Recently, even amateurs have started using gyuto knives due to the influence of cooking programs on TV.
この牛刀庖丁は第１図に示すようにをHRC50〜
52の鋼材１を使用しているもので、肉専門に使用
する場合は良いが、素人がそれを知らないで肉以
外の一般家庭の台所用として使用する場合には硬
度（一般家庭用庖丁はHRC60以上とされている）
が足りず、すぐに摩耗して切れなくなつてしまう
欠点があると共に全鋼であるため研摩（研ぐこ
と）が大変であつた。 This beef knife is H RC 50 ~ as shown in Figure 1.
52 steel material 1, which is good when used exclusively for meat, but if an amateur uses it for general household kitchen purposes other than meat, the hardness (general household knives are H RC 60 or higher)
It had the disadvantage that it quickly wore out and became uncut due to a lack of hardness, and since it was made entirely of steel, it was difficult to polish.
また、プロでも最近は肉以外の調理物に使用し
ているから常に切れ味の良い庖丁を提供すること
が望ましい。 In addition, even professionals are using knives for cooking other than meat these days, so it is desirable to always provide them with sharp knives.
これを解決するため、硬度の高いHRC60以上の
牛刀庖丁を作れば良い訳であるが、硬すぎると割
れたり、折れたり、また焼き狂いが出る欠点があ
つた。 To solve this problem, it would be better to make a gyuto knife with a hardness of H RC 60 or higher, but if it was too hard, it would crack, break, or burn incorrectly.
そこで第２図に示すように軟鉄材２の先端に鋼
材３を設け、更に鋼材３の両側にも軟鉄材２を貼
着した庖丁が考案されたが、この軟鉄材２は焼き
入れが出来ないから使用しているうちに曲がつて
しまい解決策にはならなかつた。 Therefore, as shown in Figure 2, a knife was devised in which a steel material 3 was provided at the tip of a soft iron material 2, and soft iron materials 2 were also attached to both sides of the steel material 3, but this soft iron material 2 could not be hardened. It got bent while I was using it, so it wasn't a solution.
本考案は、かかる欠点を解決したもので、強靱
性を有し、且つ硬度を有して摩耗が少なく切れ味
の秀れた万能に近い状態で使用出来る庖丁を提供
することが技術的課題である。
The present invention solves these drawbacks, and the technical challenge is to provide a knife that is strong and hard, has low wear, has excellent sharpness, and can be used in nearly all-purpose conditions. .
刃板ａの上半部分１０を焼き入れ後HRC30〜55
となる焼き入れ鋼材１０ａで形成し、刃板ａの下
半部分１１を中心にHRC60〜65の刃物鋼材１１
ａ，両側材に軟鉄材１１ｂを重合させた三枚複合

After hardening the upper half part 10 of blade plate a H RC 30~55
The cutter steel material 11 is made of hardened steel material 10a with H RC 60 to 65 centering on the lower half portion 11 of the blade plate a.
a, Both sides are made of a three-layer composite material made by polymerizing soft iron material 11b.

〔考案の効果〕
本考案は、上述の様に切刃１２は刃物鋼材１１
ａであるから切れ味がすぐれ、上半部分１０には
焼きを入れても焼き入れ温度によつて異なるが
HRC30〜55以上にならない鋼材１０ａを使用して

Figure 4 shows that the upper half 10 is made of carbon steel (JIS
The figure shows the case where three composite materials (S50C) are used, and the lower half 11 uses a composite material made by polymerizing carbon steel material (JIS SK2 type) in the center and soft iron material (SAE 1006) on both sides. It shows. (Actually, rolled material is used.) Figure 5 shows that the upper half 10 has a soft iron material (SAE 1006) in the center and carbon steel materials (JIS S50C) on both sides.
For the lower half part 11, a composite material made of polymerized carbon steel (JIS SK2 type) and soft iron (SAE 1006) is used on both sides. (Similarly, rolled material is actually used.) In Fig. 6, a single carbon steel material is used for the upper half portion 10, and a carbon steel material (JIS standard) is used in the center of the upper half portion 10.
SK2 type), and a composite material made of polymerized soft iron material (SAE 1006) is used on both sides. (The figure shows the case where the upper half part 10 and the lower half part 11 are welded.) [Effect of the invention] As described above, in the present invention, the cutting blade 12 is made of cutter steel 11.
Since it is a, it has excellent sharpness, and even if the upper half part 10 is quenched, it will vary depending on the quenching temperature.
Since the steel material 10a which does not exceed H RC 30 to 55 is used, it has appropriate toughness and will not break or bend.
従つて、切れ味良好で強靱性を有するため牛刀
庖丁としても使用は勿論のこと一般の家庭用とし
ても使用出来る万能に近い状態の庖丁を提供する
ことになる。 Therefore, it is possible to provide a nearly versatile knife that has good sharpness and toughness and can be used not only as a beef knife but also for general household use.
また下半部分１１全体を刃物鋼材１１ａにする
ものではなく、中心のみに使用しているから従来
品の全鋼に比して材料コストの低減を計ることが
出来ると共にこの刃物鋼材１１ａの両側に軟鉄材
１１ｂを重合させているからこの軟鉄材１１ｂの
一部から露出する刃物鋼材１１ａ（刃先）の研摩
は容易である。 In addition, since the entire lower half portion 11 is not made of cutter steel 11a, but is used only in the center, it is possible to reduce the material cost compared to conventional products that use all steel. Since the soft iron material 11b is polymerized, it is easy to polish the cutter steel material 11a (blade edge) exposed from a part of the soft iron material 11b.
尚、本案品の製造に当たつては、第４，５図に
示すような圧延材料を使用することにより量産が
可能となり、それだけ製品を安価に提供する等秀
れた実用上の効果を有するものである。 In manufacturing the proposed product, mass production is possible by using rolled materials as shown in Figures 4 and 5, which has excellent practical effects such as providing the product at a lower price. It is something.
