Recently, a woman in Guangzhou bought a Zhang Xiaoquan kitchen knife. When someone tried to smash garlic with the kitchen knife, the blade broke. She complained to the customer service, “I have never seen such a fragile knife, and the knife can’t shoot garlic yet?” The reply from the customer service was: “A kitchen knife can’t shoot garlic.”
The woman posted her experience online, sparking heated discussions among netizens. Upstream News contacted the customer service of Zhang Xiaoquan’s self-operated store, and the answer was: “Our knives are not recommended to shoot food horizontally. If the force is not well grasped, the handle will easily break. If you want to shoot garlic, it is recommended to use the knife surface to lightly press (garlic) .”
This broken blade is engraved with the words “50Cr15Mov” and is a high-quality stainless steel material. in:
50 means the carbon content is 50/10000 (5/1000), it can be heat treated to HRC59, and the hardness is higher
Cr represents the composition of chromium, which affects corrosion and sharpness durability, and Cr15 represents 15% chromium content
MO represents molybdenum content between 0.25-0.75, high toughness
V means that the vanadium content is not less than 0.1, and the wear resistance will be better
Master Zheng, a technician at the quality inspection center of a steel company in Chongqing, said that in order to ensure the sharpness of the tool, the manufacturer must make the hardness of the quenched steel meet certain requirements, and the higher the hardness of the blade, the sharper it will be. However, knives with higher hardness materials are relatively brittle, and the knives cannot be deformed and fractured when horizontal shooting.
Experts remind: high-grade knives are very sharp and cut things quickly and smoothly, but such knives are fragile and easy to break when tapped. For family use, it is best not to buy high-grade knives.
