What is the best material for kitchen knives?

Question 1: What is the material of the kitchen knife? How to choose a kitchen knife?

First, the basic requirements of tool materials

For kitchen knives, high hardness is the first condition. The tool removes material from the workpiece, so the material of the tool should be harder than that of the workpiece. Secondly, the tool has the characteristics of high strength and toughness. The material of the cutter has great cutting force and impact force when cutting, so the cutter must have high strength and toughness. The most important thing is that the tool material should have wear resistance and heat resistance, because the tool is used to cut other things and must have higher wear resistance than other things, and heat resistance is a good embodiment of its deformation factors.

Second, look at the sharpness of the blade.

The sharpness of the blade is the main factor of whether the tool is used for a long time, and the sharpness is determined by the sharpness and durability of the blade. Generally, the sharpness of steel tools can be divided into rough and smooth. Rough means that small teeth can be seen under a microscope after being opened with a grinding wheel. Slippery means that the cutting edge is ground with natural powder stone, and the cutting edge is particularly smooth. Although the two Sharp forms are different, it is impossible to determine which one is better. The sharpness of the blade depends on the geometric angle of the blade, so the geometric angle of the blade determines whether the blade is sharp or not.

Third, the ceramic knife analysis

Besides the steel knives mentioned above, there are also ceramic knives. Ceramic knives are developed by high-pressure precision ceramics and manufactured by high-tech nanotechnology. They have many advantages, such as wear resistance, no pores, no dirt and no rust. They have many incomparable advantages over steel knives, so now ceramic knives have been used in surgical operations in Europe and America, which shows how good this kind of material is used in knives. However, ceramic materials cannot be used to treat food by chopping, chopping, etc. Because the hardness of ceramics is not very high, it is best to choose tools other than ceramics to deal with hard food.

Question 2: Recommend a set of kitchen knives. What brand and material are better? Pay attention to the following points: First, the blade is sharp. The blade should be sharp, straight and without notch. Second, it is comfortable to use. Handle design should be humanized and comfortable to hold. Third, it is safe to use.

Stainless steel is just a general term. Many stainless steel products will still rust, but slower than steel products.

But the effect of stainless steel products is better than that of aluminum alloy products. The anodized surface of aluminum alloy is easy to be scratched, and black will be exposed when scratched by hard objects. Wood is more durable, and plastic is beautiful, but it is aging.

Question 4: What is the material of the kitchen knife? There are many kinds of knives, including machete, slicing knife, kitchen knife, peeling knife, ham knife, tomato knife, watermelon knife, bread knife and multi-purpose knife. According to the cutting edge, the whole steel knife and steel clamping knife are divided; According to materials, carbon steel, stainless steel, high carbon stainless steel knives, etc. Now many brands of knives are complete sets. Generally, a complete set of tools also includes a sharpening stick and a tool rest. 1 machete: used to cut bones. ② Slicer: used for cutting food, but not frozen meat. ③ Kitchen knife: used for cutting vegetables and fruits. ④ Peeling knife: used for planing the epidermis of vegetables and fruits. ⑤ Ham knife: used for cutting meat such as ham. 6 tomato knife: used to cut juicy and soft fruits such as tomatoes. ⑦ Watermelon knife: used to cut melons and fruits with thick peel and big fruit. Bread knife: used to cut soft food with hard skin. Pet-name ruby multi-knife: especially suitable for cutting fish fillets. , and has various uses. Pay attention to the following points when choosing tools. ① Smooth surface. Only when the surface of the tool is smooth can it really play a role in rust prevention. ② The blade is sharp. The blade should be sharp, straight and without notch. ③ Comfortable to use. Handle design should be humanized and comfortable to hold. ④ Safe use. Handle should be non-slip design, so as not to hurt users.

Question 5: What is the stainless steel material of the kitchen knife? Knife generally adopts 420J 1 or 420J2, which belongs to martensitic stainless steel with high hardness and is suitable for cutting. The general grade is made in Taigang, while the high grade is imported from Japan.
