Ha Saki :''sharp edge'' is the perfect name for the blades of the new line of professional knives in Japanese style. The blades of Hasaki knives are produced with a special stainless steel Nitro B X50CrMoV15 with nitrogen, allowing to obtain an uniform micro-structure with an excellent resistance to corrosion and a final hardness after thermic processes up to 57-59 HRC. According to the Japanese tradition, sharpening is made on one side of the blade only. Thanks to this characteristics, the material cut gets in contact with the blade only for a short time and the friction of the material cut is reduced to the minimum. This type of cutting edge is ideal to make a long and progressive cut, to slice thinly and to cut fish into fillets. There is the common conviction that a blade sharpened on one side only cuts better and more neatly, but requires more handiness with respect to a blade sharpened on both sides. The handle is made in acetal resin (POM), that makes the knife comfortable and perfectly balanced during the cut. Practical blade to cut and slice litlle foodstuffs and also perfect to bone. Blade thickness 2 mm.
