Description

Technical Field

[0001] This utility model belongs to the field of cutting tool processing technology, and specifically relates to a Damascus steel stab knife. Background Technology

[0002] Most existing sashimi knives are made from a single metal material. For example, Chinese patent CN209699156U discloses a new type of high-mirror Japanese sashimi knife, which includes a movable blade. The inner wall of the blade has a mounting cavity. The inner wall of the mounting cavity is covered with an anti-slip rubber pad by a strong adhesive. The blade is movably inserted into the anti-slip rubber pad through the inner wall of the mounting cavity, and the outer wall of the blade is tightly fitted with the anti-slip rubber pad. The blade and the sword are installed by horizontally paired fastening screws. A steel head is integrally welded to the right end of the blade. A steel column is integrally welded to the right end of the steel head. A handle is screwed to the outer wall of the steel column, and a steel tail is screwed to the tail end of the steel column.

[0003] Although the aforementioned patent documents have solved some problems in the prior art, the materials used for the knives in the aforementioned patent documents can only be processed from a single metal material. As for Damascus steel, a high-quality material, traditional Damascus steel has a multi-layered composite characteristic, with the hard steel part in the middle of the steel thickness. Since sashimi knives are sharpened on one side, and Damascus material has soft steel on both sides of the thickness with low hardness, its application in sashimi knife products is limited.

[0004] Therefore, it is necessary to design a Damascus steel sashimi knife, adopting a new structure and process for sashimi knives, so as to be able to apply the hard steel part of Damascus material to the blade part. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a Damascus steel sashimi knife. This knife is made by pre-bending a single sheet of Damascus steel. The sheet consists of a central steel core layer and soft steel layers on either side of the core layer. The non-bent portion forms the blade body, while the bent portion exposes the core layer through a subtractive processing step. The side of the core layer furthest from the bending direction is sharpened to form the blade edge. This invention alters the process structure of the hard steel in the center of the Damascus steel, allowing the blade to showcase the hard steel material, thus improving the sharpness of the edge. Furthermore, the unique surface pattern of Damascus steel enhances the knife's appearance and the overall quality of the Damascus steel itself, thereby improving the product's quality and competitiveness.

[0006] The technical problem to be solved by this utility model is to provide a Damascus steel bayonet knife, addressing the shortcomings of the prior art.

[0007] The Damascus steel stab knife is made by pre-bending a whole piece of Damascus steel sheet. After the pre-bending is completed, the whole piece of Damascus steel sheet forms a structure with an unbent part at the top and a bent part at the bottom.

[0008] A single piece of Damascus steel consists of a central steel core layer and soft steel layers on both sides of the core layer.

[0009] The non-bending portion forms the blade body portion, and the bending portion exposes the steel core layer through subtractive processing. The steel core layer at this location is sharpened on the side away from the bending direction to form the blade edge portion.

[0010] Preferably, after pre-bending, a concave surface is formed by subtractive processing on the soft steel layer on the side near the bending direction; the steel core layer is exposed at the bottom of the concave surface at the bent portion.

[0011] Preferably, an inclined surface is formed by subtractive processing on the bent portion of the soft steel layer on the side away from the bending direction after pre-bending; the bottom end of the inclined surface exposes the steel core layer, and a cutting edge is formed at the bottom end of the inclined surface.

[0012] Preferably, the steel core layer is a VG10 steel core layer.

[0013] Compared with the prior art, the positive effects of this utility model are:

[0014] (1) By improving the product's process structure and process steps, Damascus steel can be applied to sashimi knives, enhancing the quality of traditional sashimi knives, expanding the application scenarios of Damascus steel, and enriching the application of Damascus steel products in the field of sashimi knives.

[0015] (2) By changing the process structure of the hard steel material of Damascus steel in the center of the material, the blade of the sashimi knife can reflect the hard steel material of Damascus steel, thereby improving the sharpness of the blade. At the same time, due to the unique pattern on the surface of Damascus steel, the appearance of the sashimi knife and the overall product grade of Damascus steel itself are improved, thereby improving the quality and competitiveness of the product.

[0016] (3) By improving the product structure and process, it can adapt to the structure of all sashimi knife blades; at the same time, the process investment cost is low, it can adapt to mass production, and enhance the competitiveness of the product. Attached Figure Description
