が生じることになるのである。(Prior technology) The core and handle member are fixed by inserting a long and narrow fixing metal fitting into a core hole drilled in the core of the blade and a through hole drilled in the handle member and tightening the handle member. Knives that are bonded together are made by hitting the fixing metal that has been inserted through the core hole, causing the metal to expand slightly, and the expansion presses directly on the core hole to prevent the blade from rattling. Ta. However, with this method, for knives whose blades are made of the latest ceramic materials, cracks will develop from the core hole that is pressed by the fixing metal fittings, and the blade and handle will eventually come off. . For this reason, in ceramic knives, the hole in the core was made slightly larger than the outside diameter of the fixture, and the gap was filled with adhesive. However, users who are concerned about hygiene often sterilize the product by boiling it after use. If this happens, the adhesive will melt due to the heat and the connection between the blade and handle will become distorted.
（発明が解決しようとする問題点）
本発明は、刀身をセラミツクにした場合でも、
中子穴から亀裂が生ずることが無く、包丁を煮沸

る。(Problems to be solved by the invention) The present invention solves the problem even when the blade is made of ceramic.
To provide a kitchen knife that does not cause cracks from the core hole and does not disrupt the joint state of the blade and handle member even when the knife is sterilized by boiling.

はない。 Reference numeral 1 is the blade of the knife, and the core 2 has a core hole 3 bored therein. The handle member 4 is made of hard wood, and has a groove 8 formed in its center for inserting a core. Furthermore, a through hole 7 is also formed that passes through the handle member in the lateral direction. Reference numeral 5 denotes a fixing metal fitting for connecting the core and the handle member, and the male and female members are force-fitted together. The female fitting 10 expands during forced fitting. Reference numeral 9 indicates another embodiment of the fixing metal fitting, which is in the form of a rivet. Reference numeral 6 denotes a small circular piece made of an elastic material, such as synthetic resin or synthetic rubber, preferably polycarbonate resin. Third
When using the fixing metal fittings shown in the figures and FIG. 4, a small piece 6 with a round hole bored in the center is used. When using a rivet-like fixture with a sharp point, it is not necessary to drill a round hole in the small piece.
本発明の包丁を組み立てるときは、中子穴３に

で、中子２と柄部材４とは強固に結合される。 When assembling the knife of the present invention, fit the small piece 6 into the core hole 3, insert the core 2 into the groove 8 of the handle member, pass through the through hole 7 of the handle member, the core hole 3, and the small piece 6, Hit the fixing metal fittings 5 and 9. Fixing bracket 5
Since it is a forced fit, the female fitting 10 expands. The body of the fixing fitting 9 also expands by hitting its tip. Since the small piece 6 is overwhelmed by the expansion of the fixing fitting, the core 2 and the handle member 4 are firmly connected.
（効果）
本発明は以上のような構成であつて、中子穴３

中子穴３には小片６が嵌入されているので、中子
穴３と貫通孔７とが少しずれた場合にも対応する

品であるから水や熱に強く、包丁を煮沸消毒して
も柄部材と中子の結合状態が緩むおそれはないの
である。更に、固定金具を叩いて膨張させたとき
や包丁を落下させたときにも、小片６の弾性力が
そのシヨツクを吸収するから、中子穴の部分から
亀裂を生じるおそれがないのである。(Effect) The present invention has the above configuration, and the core hole 3
is formed larger than the through hole 7, and since the small piece 6 is fitted into the core hole 3, it is possible to cope with the case where the core hole 3 and the through hole 7 are slightly misaligned. Further, since the small piece 6 is a separate item made of synthetic resin or the like, it is resistant to water and heat, and there is no risk that the connection between the handle member and the core will loosen even if the knife is sterilized by boiling. Furthermore, even when the fixing fitting is struck and expanded or the knife is dropped, the elastic force of the small piece 6 absorbs the shock, so there is no risk of cracking from the core hole.
