Is it a Chinese kitchen knife that cannot be shot?

Introduction: In the past, Zhong Xuegao's "ice cream assassin" became the target of public criticism. Recently, well -known old -fashioned brands were discussed on the hot search because of the kitchen knife. So the question is: Can kitchen knives shoot garlic? How much do you know about Chinese kitchen knives?

In the Chinese kitchen scene, it is one of the basic literacy of a kitchen knife.

However, recently, "Zhang Xiaoquan's customer service said that kitchen knives can't shoot garlic" appeared on the hot search. For a while, Zhang Xiaoquan's "quality is not good, and cut corners".

Subsequently, the netizen was even more an interview video of Xia Qianliang, the general manager of Zhang Xiaoquan. In the video, Xia Qianliang said that the Chinese people cut vegetables and knives were not right. All Michelin chefs were not this way of cutting vegetables. Although Xia Qianliang himself explained that the video clips were disconnected and apologized, and the emotions of netizens were still difficult to dissolve.

Indeed, for most Chinese people, a knife cannot be competent for the common sense of shooting garlic and cucumbers commonly used in Chinese food. But aside from Zhang Xiaoquan's right or wrong (you can understand it if you can't open it ~), what is the factors that decide whether a knife can shoot garlic?

First, whether the knife is good, who said it?

"Good steel is used on the blade." Steel is a main material used in the kitchen knife. The types of steel are tens of millions of, which will mention the "steel number" -probably it can be understood as the ID number of the steel, which is one of the key indicators to judge the good or bad of a knife.

The knife steel number in the cutting knife incident is 50Cr15mov. Among them, 50 represents the carbon content of stainless steel is 0.5%, and carbon determines the hardness of the kitchen knife. The carbon content is higher and higher; CR15 represents 15%chromium in stainless steel, and the chromium content is positively correlated with the rust -proof resistance; Representatives have added molybdenum and 改 to improve more steel performance.

In theory, the higher the carbon content, the more sharp the knife is, but the knife will be more crispy. When it encounters the ingredients with higher hardness, it will not deform, but it will crack directly. Similar examples are abound. At present, the hardest material diamonds are known as high, crispy, and non -hammer.

However, 80CR and 90CR kitchen knives on the market are not uncommon, and 50CR with medium carbon content is widely used. If the garlic is cut off, except for the operation error (such as hitting the cutting board), it is likely that there is a problem with the process, such as the heat treatment process.

Thermal treatment is another key factor that determines the quality of a knife. It mainly changes the micro -structured steel structure through four basic processes of annealing, positive fire, quenching, and recovery. Take quenching as an example. After heating the knife to a certain temperature, it immediately cools with water, oil or air. This step can improve the hardness of the knife, but it is necessary to adjust what techniques, fire burning, and cooling.

After proper heat treatment, the performance of the tool steel can achieve the optimal balance, or it may also abandon some performance to maximize the maximum of other main performance.

Second, Huaxia Kitchen "Hexagon Warrior": History of Chinese Kitchen Knife Evolution

Compared with the variety of Western -style dietary knives and special knives, Chinese dietary knives are often unique to the beams and multiple uses. Cut vegetables, chopped meat, chop bone, shoot garlic, and even open bottle caps and peels. Complete the knife. A proper Chinese kitchen "hexagonal soldier".

In a broad sense, there are already kitchen knives in the Paleolithic era. At that time, humans began to use some polished sharp stones to cut food, which was the earliest kitchen knife in terms of function. The technology of stone tools and the production level of stone knives has reached a new height, and even a knife with jade as a material appears.

In the Yin and Shang dynasties, humans have experienced an epoch -making knife revolution -metal knife. As humans have mastered metal smelting skills, the bronze knife of copper tin alloy was made. The hardness of the bronze knife is not as good as the stone, but the degree of toughness and ductility and the convenience of processing are much better than the stone, so it quickly replaces the stone knife. During this period, the most famous kitchen knife was to count the knife of Chef Dingzi in "Health Lord", that is, Liang Hui Wang Xieniu was made into a nearly artistic performance. After the Qin Dynasty, the iron tool gradually began to appear, the hardness was higher, and the front blade was more favorable. After the Han Dynasty, the bronze knife was basically replaced.

After the Tang Dynasty, the "kitchen knife" category had completely separated from the category of the knife. But at this time, most of the kitchen knives were pointed knife, and the formula was close to the modern square knife until the Song Dynasty did not appear.

This aspect is because the Song Dynasty people were too good at eating, they were not tired of eating, they were not tireless, and the requirements for food cutting were increasingly improved. It turned out that the pointed knife that was only suitable for cutting was no longer applicable. At the same time, the smelting technology accumulated for thousands of years also reached a higher level in the Song Dynasty. Mining, ironmaking, and trade have made ironware have large -scale popularization conditions. More flexible knives and iron pots that can cook all things are the foundation of the Song Dynasty's dietary culture. Until the Yuan Dynasty, the title of "kitchen knife" began to appear widely, and the shape was getting closer to modernity.

Third, the old name that is hard to live in garlic, can you still have garlic this time?

Speaking of Zhang Xiaoquan on the cusp of the wind, consumers said that after the garlic incident, his Zhang Xiaoquan kitchen knife was also broken when chopping chicken legs. The person in charge of Zhang Xiaoquan previously stated that "the company may develop a knife that is specially used to shoot garlic." I wonder if it will also develop a knife with chopped chicken legs in the future.

Zhang Xiaoquan was listed on the GEM of the Shenzhen Stock Exchange in September 2021. The first day increased by nearly 400%, but the basically listed was the peak. In 2021, Zhang Xiaoquan's marketing costs reached more than five times the investment in R & D, and at the same time faced the situation of increasing income and increasing profit: in 2021, Zhang Xiaoquan achieved revenue of 760 million yuan, an increase of 32.81 % year -on -year; Yuan, a year -on -year increase of only 1.96 %. By Q1, 2022, Zhang Xiaoquan achieved revenue of 208.9 million yuan, an increase of 28.09 % year -on -year; during the same period, net profit achieved a net profit of RMB 130 million, a year -on -year decrease of 45.96 %.

At the same time, in recent years, Zhang Xiaoquan has relied on foundry production in production in recent years, which has also caused the outside world's doubts about the quality of their products -the prospectus shows that 75%of Zhang Xiaoquan's products from 2018 to 2020 depend on foundry.

This may have nothing to do with the turning over the car.

Conclusion:

As the earliest batch of national brands rated by the Ministry of Commerce as the old Chinese brand, Zhang Xiaoquan's reputation was broken within a few days of the 400 -year -old reputation, which was regrettable. Regardless of whether Chinese kitchen knives must be able to shoot garlic, at least understanding market demand and respect for consumers and products are a century -old name that should always adhere to the quality.
