What's the difference between stainless steel kitchen knife and traditional kitchen knife?

Stainless steel kitchen knives have become very popular in daily life. Next, Bian Xiao will introduce you to the difference between stainless steel kitchen knives and traditional kitchen knives.

First of all, the materials are different:

Needless to say, as we all know, there are many kinds of stainless steel products. Why stainless steel kitchen knives don't rust is mainly because appropriate elements such as chromium, nickel and titanium are added during steelmaking. The addition of these elements can play a role in rust prevention and corrosion protection of steel, and can improve the appearance of steel and make it more beautiful.

However, old-fashioned kitchen knives are generally made of raw steel from steel mills. This raw steel is not added with any other chemical elements in the smelting process, so most of the kitchen knives made are not as beautiful as stainless steel.

Second, the process is different:

Stainless steel knives are mostly produced by modern technology in general tool factories, using cold rolling technology, directly formed by machines, and finally shaped and polished by machines. Stainless steel kitchen knives have not been forged in the fire, so the blade is generally tough but hard, and it is difficult to sharpen it after the blade is blunt.

Old kitchen knife technology: China has been making knives for thousands of years. There are many famous knives in many places, and each knife factory has its own different technology. Most of them follow the traditional forging knife manufacturing process. After the steel is forged in the furnace, the heavy impurities in the steel are removed, and the density of the steel is strengthened, making it harder and tougher. Finally, it is finished by artificial quenching, oil cutting and shaping. Most knives forged by fire are very sharp, durable and easy to grind.
