Department Store Show: Kitchen knife shopping guide

There are many kinds of kitchen knives on the market, with different functions, which makes people cross eyes。So how should kitchen knives be chosen, department store exhibition please read this purchase guide。

First, purchase points

　　1. Look at the material。

　　The department store learned that the common materials of kitchen knives on the market at present are carbon steel, stainless steel, ceramics, etc., which have different advantages and disadvantages。

　　1) Carbon steel material

　　Carbon steel kitchen knife is relatively hard, but also easy to make a high-hardness blade, retention is better, and because of the difference in microstructure, carbon steel knife is easier to sharpen than stainless steel knife, its cutting force is relatively good。Household carbon steel knife prices are also more affordable, is a cheap knife。

　　Disadvantages: carbon steel knife due to its material, when cutting some ingredients, the ingredients will react and oxidize。In addition, carbon steel knives are prone to rust and should be dried after each use。When not in use, it can be wiped and stored with lard。

　　2) Stainless steel

　　Stainless steel knives are now the mainstream of home kitchen knives。Stainless steel knives will be marked with some numerical marks, such as 30Cr13, that is, 0.3% carbon, 13% chromium, and the addition of molybdenum and vanadium refined grains, the number before Cr represents the content of carbon in the steel, in general, the higher the carbon content of the knife, the better the hardness。Because stainless steel knives contain active metals in addition to iron, stainless steel knives are not easy to rust, but also more beautiful, easier to store。

　　Disadvantages: Stainless steel knife cutting vegetables as carbon steel knife feel, and the blade is relatively difficult to sharpen, and the better the rust performance of the knife hardness may be lower, the two characteristics are contradictory and unified。

　　3) Ceramic material

　　At present, most of the ceramic knives on the market are processed with a nanomaterial "zirconia"。The ceramic knife is characterized by very high hardness, light viewing, high temperature resistance, corrosion resistance, durable sharp, stable nature will not react with ingredients and destroy the natural taste of some foods, and the ceramic knife will basically not rust。

　　Disadvantages: Ceramic knife is very brittle, to be handled lightly, can not fall to the ground, it is easy to break, can not be used to cut, smash, pry, pick hard things。

　　2. Look at the function。Different functions are the main conditions for purchase，It used to be that a chef's knife could do almost all the chopping in the kitchen，With the improvement of living standards，The use of tools is also becoming more detailed and diversified，So to meet different needs，Kitchen knives are designed according to different usage scenarios，And highlight a certain performance of the kitchen knife，Can be selected according to different use requirements。For example: Kitchen knife: can cut, but can not cut thick bone;Machete: suitable for cutting bones and hard food;Blade knife: suitable for fine cutting work, slicing, cutting;Boning knife: Used for peeling, boning, etc。

　　Second, use precautions

　　It is learned that the knife should be cleaned in time after use, so as not to stick to the food on the knife, after cleaning, dry or dry in time, do not use cooking oil for a long time to prevent rust speed up, and use different types of knives as far as possible to use separately, which can extend the service life of the knife。In addition, the kitchen knife is relatively sharp, in order to avoid children's accidental injury, the kitchen knife should be placed in a higher position in the kitchen, but do not hang on the wall, to avoid the hook loose the kitchen knife fall。To avoid unnecessary harm to children。

　　The above is the tool knowledge introduced by the small edition of the department store exhibition. I hope you can refer to it. If you want to know more about the tool knowledge, you can consult the exhibition site。
