Reasons why Western kitchen knives need anti-rust oil or cooking oil

The reasons why western kitchen knives need anti-rust oil or cooking oil can be elaborated in the following aspects:
1. Material properties
Western kitchen knives are mostly forged from high-quality stainless steel or carbon steel. Although stainless steel itself has a certain degree of corrosion resistance, but in the process of long-term use, especially in the humid or contact with corrosive substances (such as acidic ingredients) in the environment, rust may still occur. Carbon steel, on the other hand, although sharp, is more prone to rusting compared to stainless steel. Therefore, the use of antirust oil or cooking oil can form a protective film on the surface of the knife to isolate it from air and moisture, thus reducing the risk of rust and corrosion.
2. Environment
In western cooking, the variety of ingredients and the complexity of cooking methods make it possible for kitchen knives to come into contact with a variety of ingredients and seasonings, including some corrosive substances during use. In addition, the kitchen environment is often humid and greasy, which also increases the likelihood of the kitchen knife rusting. Therefore, regular application of anti-rust oil or cooking oil can protect the kitchen knife from environmental factors.
3. Maintenance requirements
Western chefs pay more attention to the maintenance of knives, as they believe that sharp knives are one of the keys to successful cooking. Therefore, in order to keep their knives sharp and prolong their lifespan, chefs take a variety of maintenance measures, including the application of anti-rust or cooking oils. These oils and greases can form a lubricating film on the surface of the knife, reducing the friction between the blade and the ingredients, thus protecting the blade from wear and tear.
4. Practicality and Convenience
Rust preventive oil or cooking oil, as common maintenance materials, are not only easily available but also relatively inexpensive. They can be used to maintain not only kitchen knives but also other metal kitchenware and tools. In addition, the process of applying these oils and greases is relatively simple and quick, making them suitable for use in a busy kitchen environment.
In summary, Western kitchen knives need rust preventative oils or cooking oils to reduce the risk of rusting, protect the sharpness of the blade and prolong its life. The practicality and convenience of these oils and greases in the kitchen environment has made them one of the common materials used by Western chefs to maintain their knives.
