DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The existing kitchen knives have average strength and service life, and the knife surface is easily damaged by dents, cuts and the like, which shortens the service life of the knife.

[0021] In view of this, a martensitic and austenitic stainless composite steel kitchen knife is provided. The strength of the knife is ensured by setting the martensitic stainless steel layer and the austenitic stainless steel layer through the cooperation between the martensitic stainless steel layer, the austenitic stainless steel layer and the sharpening layer, thereby solving the problem that the strength and service life of the existing kitchen knives are average, the surface of the knife is easily damaged by dents, chip marks and the like, and the service life of the knife is shortened.

[0022] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0023] Embodiment 1: By Figure 1-2 It can be seen that a martensitic and austenitic stainless composite steel kitchen knife comprises a knife 2, a steel handle 1 is installed on one side of the knife 2, a sharpening layer 6 is arranged below the knife 2, a martensitic stainless steel layer 4 and an austenitic stainless steel layer 5 are arranged inside the knife 2, and an auxiliary tool 12 is arranged on one side of the steel handle 1;

[0024] In the specific implementation process, it is worth pointing out that the main model of the martensitic stainless steel layer 4 is 410, and its main material is high-strength chromium steel with good wear resistance. The austenitic stainless steel layer 5 has strong rust and corrosion resistance, excellent plasticity and toughness, and is convenient for stamping.

[0025] Specifically, when using the martensitic and austenitic stainless composite steel kitchen knife, the strength of the knife 2 is ensured by setting the martensitic stainless steel layer 4 and the austenitic stainless steel layer 5 through the cooperation between the martensitic stainless steel layer 4, the austenitic stainless steel layer 5 and the sharpening layer 6, thereby solving the problem that the strength and service life of the existing kitchen knives are average, and the surface of the knife 2 is easily damaged by dents, cuts and the like, which shortens the service life of the knife.

[0026] Embodiment 2: By Figure 1-4 It can be seen that the auxiliary tool 12 is a bottle opener 9;
