The knives are a must-have tool in the kitchen. For any housewife or chef, buying a good knife is the biggest thing that helps them. There are many kinds of kitchen knives on the market; every family says that their knives are good. Of course, Wang Po sells melons, and self-selling is also a human nature, but consumers often have no choice when they choose. So, how do you buy kitchen knives? Let’s take a look at the following small series.
How to choose kitchen knives
First, the sharp edge
1. The material is usually steel, stainless steel, carbon steel (such as shell steel), or ceramic (zirconia) Damascus and so on. Different materials determine the hardness of the finished tool. Can it be understood that the higher the hardness, the higher the sharpness? It should be said that it is not completely correct, because the “fast” of the kitchen knife depends on the degree of the cutting edge, the softness and so on. For example, ceramic knives usually have higher hardness than stainless steel knives, but users often find that stainless steel knives are not fast during use. This is because the degree of the ceramic blade edge is not too small due to the limitation of the material, otherwise it will be directly brittle. Of course, ceramic knives also have the advantage of not corroding. Hardness: 3cr13<4Cr13<5Cr15<8Cr15<9Cr15≈ Carbon steel <Damascus <ceramic (zirconia).
2. The method of cutting edge is divided into machine edge cutting and manual cutting. Therefore, in terms of sharpness, the hardness of the steel is higher, the degree of cutting edge is smaller, the arc of the cutting edge is softer, and the non-linear straight down kitchen knife will More “fast”, better use, especially a slicing knife. Therefore, the same material, the process of the slicing knife is definitely more sharp than the cleaver, this is determined by the degree of the cutting edge.
Second, the use of comfort.
The design of the shank should be humanized and comfortable to hold. The main materials in the shank are wood, engineering plastics, steel handles, etc., each with its own advantages. Generally speaking, the shape of the kitchen knife for stamping is better and more refined; the traditional forging tool uses wooden handles (mostly round handles), and now some traditional cutter manufacturers have begun selling other kitchen knives with other handles.
Third, the use of security. The handle should have a non-slip design and will not hurt the user. Needless to say, the minimum requirements, in addition to the difference between stamping and red hot forging process:
Simply put, a large piece of steel plate (such as a thickness of 2 mm) is used to directly punch out a complete blank by a punching tool, and then perform subsequent cutting, surface treatment, heat treatment, upper shank and other processes. Into the finished kitchen knife. The advantages of this process are high efficiency and cost advantages, high degree of mechanization, better surface treatment, high degree of standardization and perfect details. At present, the mainstream tools in supermarkets and other markets are basically this kind of technology (Guangdong Yangjiang is the representative, 18 sons, smart wife, etc.)
The biggest difference from the stamping process is the knife forming stage. Forging is to burn the steel embryo (usually a block) to a red hot state, through repeated beatings (now using a machine hammer), to shape the initial knife embryo, and then manually open the blade (frustration), surface treatment, heat treatment, etc. The finished kitchen knife usually has a thick back, a thin mouth and a wedge-shaped cross section. Compared with the stamping and forming kitchen knife, the forged kitchen knife steel is more compact, the blade body stress distribution is more uniform, and the sharpness is better. The disadvantage is that the production is difficult to increase and the cost is higher, and the process details are relatively poor.
Well, I have learned so much about the knowledge of the knives. Let’s follow the Xiaobian and learn about the popular kitchen knives.
