Best Kitchen Knife Buying Guide
Jul 31,2022 | Fzkaly
The main criteria for measuring a kitchen knife are sharpness and toughness, and the material of the kitchen knife and the content of different ingredients will affect the knife's performance.
1. Sharpness and toughness
Sharpness: One of the important indicators of whether a kitchen knife is good or bad. It is mainly measured by HRC(Rockwell hardness). A good kitchen knife usually has a hardness of 56+. Kitchen knives with high sharpness are generally above 60 HRC. However, the hardness of kitchen knives is too high, which will cause the toughness to decrease, and it is easy to cause cracks when used.
Toughness: The ability of kitchen knives to resist fracture is also one of the most important indicators. Knives with poor toughness are like glass; the harder they are, the more fragile they are.
2. Material selection
Stainless steel: The carbon content is uncertain, the chromium content is more than 13%, the toughness is good, and it is not easy to rust. Stainless steel makes excellent knives that are durable and can get very sharp.
Triple steel: Two pieces of stainless steel on the outer layer, and a layer of high-hardness high-carbon steel in the middle. It has good toughness and high sharpness.
Damascus steel: Extremely sharp. It can make beautiful patterns on the outer layer of the finished knife metal.
Next, let us continue to subdivide these steel materials.
It is to first use relatively soft steel (low-carbon steel or wrought iron) to forge the basic shape of the knife, then use a thin piece of high-carbon steel to wrap one side of the knife, and finally forge it into a blade. In this way, the blade part can be hard and sharp enough, and the blade part will not break easily because it is too hard.
Clamp steel is the opposite of clad steel. It is made of harder steel and soft steel is sandwiched on both sides. The soft steel on both sides is elastic enough to wrap the high-carbon steel inside, so that the steel in the middle will not break even if it is bent.
Clamp steel can make a double-edged sword, and there is no need to be very careful in polishing, and the strength of the main structure is even higher.
The disadvantage is that clamp steel is more expensive in comparison, and clamp steel consumes more high-carbon steel than clad steel, so the cost is relatively high.
It is to cut a small hole in the soft steel where the blade needs to be made, and then insert a piece of high-carbon steel into it. Compared with the first two forms, inlaid steel can be made with double-edged blades at will, and there is no worry about being resistant to polishing. At the same time, it is more material-saving, and the process is simple and easy to mass produce. Its high-cost performance made this technology not only used in swords in ancient times, but also in kitchen knives, scissors, axes, etc., all used this technology for production.
The different soft and hard steels are stacked together, and then repeatedly folded and forged, so that the sword created in this way will form a pattern of soft and hard supporting each other inside. When the harder steel cracks, the softer steel can prevent the cracks from continuing to crack, while the harder steel can continue to support the overall structure.
The overall performance of the knives made in this way is much more stable than that of the sword made of inlaid steel, clip steel, and clad steel. At the same time, due to the different glosses of high-hardness and low-hardness steel, the knives will also show a charming and smooth pattern. The Damascus knife, the top of the world's three famous blades, are made on this principle.
