Molybdenum and tungsten further improve its toughness and wear resistance. The combination of these elements, along with the powder metallurgy process, results in a steel that is incredibly hard and durable. The performance of K390 is primarily defined by its ability to maintain a sharp edge for an exceptionally long time. This makes it ideal for knives used in industries where刃 frequent sharpening is impractical or undesirable, such as manufacturing, woodworking, and meat processing. Knives made from K390 are also popular among serious knife enthusiasts who demand the highest levels of edge retention. The wear resistance of K390 is so high that it can outlast many other steels, even in demanding cutting tasks. This means that users can go longer between sharpenings, which saves time and effort. However, the extreme hardness of K390 also makes it more challenging to sharpen than many other steels. It typically requires specialized sharpening equipment, such as diamond stones or ceramic rods, and a skilled hand to achieve a fine edge. Despite the sharpening challenges, the superior edge retention of K390 makes it a worthwhile trade-off for many users. K390 is not a stainless steel, meaning it has relatively low corrosion resistance compared to steels like Vanax or 14C28N. This means that knives made from K390 require more care and maintenance to prevent rust and staining. They should be cleaned and dried thoroughly after use, and may benefit from occasional oiling to protect the blade. The toughness of K390 is good for a high-wear-resistance steel, but it is not as tough as some other steels. This means that knives made from K390 may be more prone to chipping if subjected to heavy impact or lateral stress. However, in typical cutting applications, K390 offers a good balance of wear resistance and toughness. Overall, K390 is a top-tier steel for those who prioritize edge retention above all else. Its exceptional wear resistance makes it a standout choice for knives that are used for demanding cutting tasks, even though it requires more effort to sharpen and maintain. If you are looking for a knife that can hold its edge for an incredibly long time, K390 is an excellent option to consider.
