In this day and age people to pursue high quality life.
The kitchen knife, for example, in the advanced market, the pursuit of quality you can buy zwilling, WMF, such as German world famous brand.
They like other made in Germany is the representative of the high-end lifestyle.
Most of the world's top products in the field of kitchen knife from Germany and Japan.
Japanese kitchen knife enjoys high reputation in their field, their performance quality often is better than German counterparts, and their price in most cases is much cheaper than with German kitchen knife, but they are not familiar.
With the popularity of western and Japanese cuisine, young Chinese urban households directly into the arms of foreign goods.
But they did not know the real difference between import kitchen knife.
Why do you want to pursue a good knife?
Blade shape, center of gravity, will affect the knife grip.
Advanced kitchen knife design to pursue the balance of each user can instantly feel the light blade, comfortable grip and incomparable sharp.
People in the domestic market is not so easy to see the Japanese kitchen knife.
Buy online, strange shapes and unfamiliar name, total prohibitive.
Today we are simple to understand the ashkenazi kitchen knife and Japanese kitchen knife material difference.
Blade sharpness and durability, the influence of the material is decisive.
On material, Japanese kitchen knife dominant.
Hardness is the key, the higher the hardness, the sharp knife, the better the durability, but toughness would fall at the same time, the novice use easy to damage, and antirust performance will decline, maintenance difficulty will increase.
Hardness, toughness and antirust performance are related.
The hardness of the key, is determined by the carbon.
The hardness of knife class usually use rockwell C scale (
HRC)
To represent.
Generally with the rockwell hardness of the steel kitchen knife HRC in 55 -
65.
But usually, the hardness of the big Japanese dao, generally in the 60 -
62, Germany knife slightly lower hardness, generally in 55 -
The hardness of 58, between Chinese dao is in commonly 50 or so.
Zirconia ceramic knife has the highest hardness, is beyond the scope of determination of HRC.
According to AD, the HRC 85 above, but they are most afraid of be dropped, it is easy to break.
The material of ashkenazi knife ashkenazi zwilling, WMF and other mainstream type knife, steel is mostly used by 1.
4116 or call X50CRMOV15.
This kind of steel carbon content is only 0.
5%, the hardness is generally between HRC54 ~ 57, introduction to the cutting tool in a wide range of industries are widely used in Europe in the making.
Features are: good processing, hardness is low;
Good toughness, good rust prevention;
The cost is cheap, poor stability, easy to edge.
Heavy material is a kind of Oriental tradition, China is also such.
The Japanese this confidence, but also the pursuit of quality are decided by the social habits.
Japanese dao hardness is generally above HRC60, the Japanese dao like to use all kinds of high strength material as the blade material, the cutting tool general external characteristic as high hardness, a very sharp.
The corresponding poor toughness, easy to rust, novice intractability, difficult hardships maintenance.
What is made of Japanese dao?
In the description of the Japanese dao with makings, people often see VG -
10, the white paper, green paper these strange noun, the noun carries strong Japanese industrial heritage.
VG -
10 is a dedicated to my special steel development tool steel, due to the carbon content reaches 1.
HRC60 15% 0%, chrome content, hardness, edge strength, stability, lasting, sharpness is balanced, and rust is not bad, and many brands are in use.
Famous Ann to steel was developed by Hitachi metals Ann to steel mills, is made using modern technology 'imitation jade steel'.
Jade steel is the material that the ancient samurai sword, the carbon content is about 1.
0 to 1.
7%, the ancient Japanese in a terrible shortage of resources, backward technology, use of low temperature iron smelting method for sponge iron, after selection, smelting folded forging and the material over and over again.
Ann to steel main points white paper, green paper, yellow paper (
Is used to make more scissors, tools, etc. , have been eliminated)
, a series of several silver paper, unlike standard not unified jade steel, Ann to steel manufacturing standard and unified, alloy ratio in strict accordance with the no. 1, 2, 3, such as classification, such as the carbon content is lower than 2 white paper 1, white paper and green paper no. 2 carbon and tungsten content and low Yu Qing paper 1.
Let all bladesmith, artisans, can be in strict accordance with the unified standard of choose and buy materials, to production.
Ann to steel hardness above HRC60.
Carbon content from the lowest white 2, 1.
1 0 to the highest super green paper.
5% range, good rigidity, excellent stability, green white paper no. 1 and no. 1 is better than VG10 properties;
Since there is no chrome, polished sex is very good, very easy can sharpen, suitable for professional chefs;
Dry place, anti-rust property is poor, often wet weather is oiled.
Today more hard than Ann to steel and powder steel, made of steel with powder metallurgy technology, a lot of first-line brand the most expensive series are made the most expensive steel powder series, them to occupy the position of high-end kitchen knife steel.
Japanese kitchen knife contains many characteristics of old process, and continuously explore materials technology.
Their senior can use touch, taste and visual to fully experience, because they are stuck in the modern tradition.
