KNIFE CARE

Carbon steel requires much more care than stainless steels. The basic principle of the maintenance of carbon steel knives is to wipe them dry, leaving a dirty knife even for a moment will quickly cover it with a patina. After wiping the knife dry, it is best to lubricate it with a small amount of camellia oil, which will additionally protect the blade. Leaving a wet knife to dry on its own will result in the appearance of small spots of rust. It is completely unacceptable to wash the knives in a dishwasher, chemicals and high temperature will negatively affect the handle and the blade, it can also lead to permanent damage to the knife. The knife is used only for cutting soft, boned and non-frozen products. If the blade comes into contact with the bone, it can chip. When cutting, do not twist the knife from side to side, as it may break the tip if the knife is jammed in the product. The wood and plastic boards recommended by us, cutting on glass or stone boards is prohibited, it will lead to an accelerated process of blunting the knife and possible nicks. The knife should only be used as a cutting tool, the thin, sharp design perfectly cuts the products, but when you try to open the jars, the blade may chip.

Japanese high speed powder tool steel from Hitachi Steelworks. It is recognized by many users as the best rusty powder steel on the market. Due to the mixture of incredible amounts of carbide-forming elements, the hardness and strength of this steel are extremely high. Chrome, improving e.g. tensile strength, sharpness and corrosion resistance, molybdenum to improve machinability and strength, vanadium and tungsten to improve wear resistance and hardness, with a large addition of cobalt (which increases the positive effect of each of the above-mentioned elements) make knives made of HAP 40 reliable. The hardness achieved by this steel is unbelievable, reaching 64-68 HRC. This steel is distinguished by amazing sharpness, but due to its hardness sharpening will be a challenge. It is a steel that is partially resistant to corrosion, but it is worth paying attention to its maintenance (cleaning and oiling), as it may rust. Is this steel suitable for knives then? I think that after reading the description, you have no doubts, this steel is great for extreme cutting, you can count on its strength and hardness. However, it needs more care than typical stainless steel, but with proper care, knives made of HAP 40 steel will serve you faithfully
