What qualities should a good knife have?
The most important attributes of a knife are undoubtedly its use and sharpness. From a large bone-cutting knife to a small bone-cutting knife, the use is different, and the design ideas are also different. As for the material of the knife, stainless steel is still the main one so far, but ceramic knives have emerged in recent years and occupied a lot of market share.
Ceramic knives are sharper, corrosion-resistant, and anti-oxidation. They are not easy to wear and rust, and they will not affect the original taste of the food. These advantages seem good, but we must also consider the fatal shortcomings of ceramic knives. They are too brittle and cannot be used to cut hard objects. They may be damaged if they fall, and individuals cannot sharpen ceramic knives.
A set of knives is needed to meet the needs of daily cooking. According to the type of use, the kitchen generally needs about five knives, namely a large kitchen knife, a medium-sized chef knife, a small fruit knife, and kitchen scissors.

Large kitchen knives are mainly used to chop bones and meat and to handle large pieces of meat ingredients. It should be noted that some knives are not sharp enough, so they are heavier, and it is usually "strong to work miracles" when chopping bones. Nowadays, technology is constantly upgraded, and high-quality kitchen knives can make up for the weight with sharpness and try to balance durability, sharpness, weight, and other attributes.
Remember to consider this little change. For people who cook frequently, a weight reduction of 10g will reduce a lot of pressure on the wrist and avoid wrist sprains or overwork injuries.
Medium-sized chef knives are responsible for cutting small pieces of meat or vegetables. Chef knives are lighter and compact, and the pressure on the wrist will not be too high when handling ingredients for a long time. This type of knife is similar to a ceramic knife, and its characteristics are light and sharp enough.
Small fruit knives can be used not only to peel fruits but also to cut meat strips, carve fruits and vegetables, etc. However, it is indeed difficult for people who are new to the kitchen to cut meat strips and carve fruits and vegetables.
Kitchen scissors are used to handle some ingredients with high toughness or hardness, which are not convenient to handle with kitchen knives and chef knives. We often see chefs using scissors to handle ingredients in spicy hot pot restaurants and barbecue stalls. Kitchen scissors are also constantly upgraded, and new functions are added.

How to choose knives?
A set of five knives can basically achieve the needs of users, but facing countless knife brands, how to choose is difficult. In fact, choosing other products is similar. When buying knives, we only consider factors such as quality, demand, and price.
Let's talk about quality first. When selecting stainless steel knives, the first thing is to look at their material. There are many kinds of stainless steel, but when it comes to great steel, many people may think of the famous "Damascus steel" for the first time. This material is not just a name. The ancients used it to make weapons, and modern people used it to make kitchen knives, which is quite like turning swords into plowshares.
Modern Damascus steel is generally forged from multiple layers of multiple sheets of steel, which can ensure both toughness and strength. The blade density is higher than that of ordinary steel, and it is also more durable and corrosion-resistant. If you ask what the disadvantages of this material are, it is probably that the cost needs to be lowered. The price of kitchen knives made of this steel is usually not cheap.
If it is a medium-sized chef's knife or a small fruit knife, ceramic material can also be selected, but it is better to have a larger kitchen with enough space to place ceramic knives.

Titanium carbide (TiC) is an important component of ceramic tool materials
Titanium carbide (TiC) demonstrates outstanding performance. Especially in the manufacture of high-performance cutting tools. Here are some key features and advantages of titanium carbide in ceramic tool applications:
High hardness and wear resistance: The hardness of titanium carbide ceramic tools is usually much higher than that of traditional carbide tools, which makes them perform well when machining hard materials such as high-hardness steel, cast iron, high-temperature alloys, etc., and can withstand higher cutting speeds and greater cutting forces, reduce wear, and extend tool life.
High-temperature stability: TiC ceramic tools can still maintain good hardness and wear resistance at high temperatures, which means that they are not easy to soften during continuous high-speed cutting, suitable for dry cutting or high-speed cutting, reducing the use of coolant, and conducive to environmental protection and cost control.
Chemical stability: Titanium carbide has good stability to many chemicals, does not easy to react chemically with the workpiece material, reduces the chemical wear of the tool, and is especially suitable for use in corrosive environments.
Low thermal expansion coefficient: TiC ceramics have a low thermal expansion coefficient, which helps to reduce thermal deformation, improve machining accuracy, reduce vibration during cutting, and improve workpiece surface quality and machining efficiency.
Application of Titanium Carbide (TiC) in Ceramic Tools
Whisker toughening: By introducing titanium carbide whiskers into a matrix such as alumina, the fracture toughness of ceramic tools can be further improved so that while maintaining high hardness, they can also withstand a certain degree of impact load and reduce the risk of brittle fracture.
Composite material application: Titanium carbide is often used in combination with other ceramic materials (such as alumina Al2O3) to form composite ceramic tool materials, which combine the advantages of two or more materials, improve hardness and wear resistance, and improve toughness to achieve better comprehensive performance.
Environmental advantages: Due to their high durability, TiC ceramic tools reduce the number of replacements throughout their life cycle, thereby reducing resource consumption and waste generation, which meets the requirements of sustainable development.
