Description

Technical Field

[0001] This utility model relates to the field of cutting tool technology, specifically a tungsten carbide alloy anti-rolling cutting tool. Background Technology

[0002] Knives are indispensable tools in people's daily lives and play a key role in kitchen cooking. With the improvement of living standards, people have put forward higher requirements for the performance, durability and user experience of knives. Due to the advantages of tungsten carbide, such as high hardness, high wear resistance and good corrosion resistance, it has gradually become an ideal material for knife manufacturing. Compared with traditional knife materials, tungsten carbide knives have a longer service life and can significantly reduce the frequency of knife replacement.

[0003] However, even when using tungsten carbide alloys in existing technologies, knives may still develop a chipped edge when facing high-strength, high-hardness objects. Chipped tungsten carbide alloy knives not only reduce cooking efficiency but may also affect the appearance and taste of food; they also increase the difficulty of food preparation, have low practicality, and are not convenient to meet people's needs.
