Description

Technical Field

[0001] This utility model relates to the field of cutting tool technology, and in particular to a blade and bread knife with an asymmetrical cutting tooth structure. Background Technology

[0002] A bread knife is a tool used to cut bread. Because bread is soft and contains many fibers that are difficult to cut, it is easy to deform the bread when cut with a regular knife, affecting its appearance. Therefore, a bread knife is commonly used to cut bread.

[0003] A bread knife typically consists of a handle for the user to grip and a blade attached to the handle. The blade has a single-sided serrated edge. When cutting bread with a bread knife, the single-sided serration makes it easier to cut the bread fibers, reducing pressure from the blade and thus preserving the bread's soft shape.

[0004] However, this single-sided serrated structure makes the bread cut surface uneven, produces more bread crumbs, and creates a sticky feeling during cutting, reducing the smoothness of cutting and affecting the user experience. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a blade and bread knife with an asymmetrical tooth structure. This solution enables smoother and less effort when cutting bread, and can make the bread cut surface flat and reduce the generation of bread crumbs.

[0006] To achieve the above objectives, the present invention provides a blade with an asymmetrical cutting tooth structure, comprising a blade body, wherein a cutting edge is provided on the blade body, and cutting teeth are respectively provided on the left and right sides of the cutting edge, and the cutting teeth on the left and right sides are asymmetrically staggered.

[0007] As a further improvement of this utility model, the cutting teeth on both sides of the blade include large cutting teeth and small cutting teeth, and the large cutting teeth and small cutting teeth on each side are connected and arranged in a cycle.

[0008] As a further improvement of this utility model, the large cutting teeth on the left and right sides of the blade are asymmetrically staggered, and the small cutting teeth on the left and right sides of the blade are asymmetrically staggered.

[0009] As a further improvement of this utility model, the included angle between the connected large cutting edge and small cutting edge is greater than 90 degrees.

[0010] As a further improvement of this utility model, the included angle between the connected large cutting edge and small cutting edge is 115 degrees.

[0011] As a further improvement of this utility model, both the large and small cutting teeth are arc-shaped structures.

[0012] As a further improvement of this utility model, the arc length of the large cutting tooth is greater than the arc length of the small cutting tooth, and the arc radius of the large cutting tooth is greater than the arc radius of the small cutting tooth.

[0013] As a further improvement of this utility model, the large cutting edge is provided with a chip removal groove.

[0014] As a further improvement of this utility model, the chip removal groove is configured as an arc-shaped structure that slopes upward and outward from the large cutting edge.

[0015] This utility model also provides a bread knife, including a handle and the aforementioned blade, wherein the blade is connected to the handle.

[0016] The beneficial effects of this utility model are as follows: In this utility model, the blade teeth are arranged in an asymmetrical staggered configuration on both the left and right sides. During the bread cutting process, the contact area between the blade and the bread can be effectively reduced, making it less likely for the bread to stick to the blade. This reduces the friction between the blade and the bread during cutting, improves the smoothness of cutting, achieves the effect of saving effort, and makes the bread cut surface smooth and neat, effectively reducing the generation of bread crumbs.

[0019] Marking description: blade 1, blade edge 2, cutting edge 3, large cutting edge 31, small cutting edge 32, included angle 33, chip removal groove 34, handle 4. Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] like Figure 1 , 2 As shown, a blade with an asymmetrical cutting edge structure includes a blade body 1, on which a cutting edge 2 is provided. Cutting edges 3 are provided on the left and right sides of the cutting edge 2, and the cutting edges 3 on the left and right sides are asymmetrically staggered. The asymmetry refers to the fact that, with the blade body 1 as the plane of symmetry, the cutting edges 3 on the left and right sides are asymmetrically arranged relative to the blade body 1. Specifically, the cutting edges 3 on both sides of the cutting edge 2 include large cutting edges 31 and small cutting edges 32. The large cutting edges 31 and small cutting edges 32 on each side are sequentially connected and arranged in a cyclical manner, while the large cutting edges 31 on the left and right sides are asymmetrically staggered, and the small cutting edges 32 on the left and right sides of the cutting edge 2 are also asymmetrically staggered.

[0022] By using the double-sided asymmetrical staggered arrangement of the blade teeth 3, the contact area between the blade 2 and the bread can be effectively reduced, making it less likely for the bread to stick to the blade body 1. This reduces the friction between the blade 2 and the bread during cutting, improves the smoothness of cutting, achieves a labor-saving effect, and makes the bread cut surface smooth and neat, effectively reducing the generation of bread crumbs.

[0023] Both the large cutting tooth 31 and the small cutting tooth 32 are arc-shaped structures. The arc length of the large cutting tooth 31 is greater than that of the small cutting tooth 32, and the arc radius of the large cutting tooth 31 is greater than that of the small cutting tooth 32. The included angle 33 between the connected large cutting tooth 31 and the small cutting tooth 32 is 115 degrees. The included angle between the cutting teeth of traditional bread knives is mostly 45 degrees, and the cutting teeth are relatively sharp. In this embodiment, by setting the large and small cutting teeth 31 and 32 and the included angle 33 as described above, the lines of the blade 2 are enhanced, while the continuous cutting teeth 3 are set smoothly without sharp angles, which is safer than traditional cutting teeth 3 and less likely to cut the hand. It should be noted that the included angle 33 between the connected large cutting tooth 31 and the small cutting tooth 32 is not limited to 115 degrees. In other embodiments, the included angle 33 between the connected large cutting tooth 31 and the small cutting tooth 32 is greater than 90 degrees to achieve the above effect.

[0024] Furthermore, a chip removal groove 34 is provided on the large cutting tooth 31. The chip removal groove 34 is an arc-shaped structure that slopes upward and outward from the large cutting tooth 31. Air can enter the cutting surface along the chip removal groove 34, further preventing bread from sticking to the blade 1, thereby further improving the cutting smoothness and reducing the generation of bread crumbs.

[0025] The aforementioned blade 1 is used in bread knives, which include the blade 1 and the handle 4, with the blade 1 attached to the handle 4. In addition, the aforementioned blade 1 can also be used in kitchen knives, fruit knives, and other similar knives.

[0026] The above-described embodiments are only for illustrative purposes and are not intended to limit the present invention in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present invention without departing from the scope of the technical features of the present invention shall still fall within the scope of the technical features of the present invention.
