Discover Yu Kurosaki Gekko Japanese knives on KnifeLeader.eu! Japanese blacksmith Yu Kurosaki offers you Gekko knives made from top-quality materials. Yu Kurosaki Gekko knives feature a San Maï blade structure: the core is made from the latest alloy, HAP40 powdered steel, and is coated with softer steel to protect and balance it. HAP40 powdered steel is in fact a high-end hybrid alloy that is difficult to obtain and work with, which is why only the greatest blacksmiths like Yu Kurosaki use it for their handcrafted Japanese knives. We call it a hybrid alloy because, although it contains around 1.3% of the carbon essential to its rigidity, it is neither a carbon steel nor a stainless steel: HAP40 is a semi-stainless steel. The blade of your handcrafted gekko knife achieves a very high hardness of 65 HRC, guaranteeing an extremely sharp, long-lasting edge. Another advantage of this top-of-the-range alloy is that, even with its high rigidity, it remains easy to maintain with a Sharpening stone if required. In fact, sharpening sessions can be spaced out as HAP40 steel holds its edge 3 to 5 times longer than traditional steels. Yu Kurosaki has then equipped these top-of-the-range knives with a light yet robust oak handle, and here again he has put all his know-how to good use. In fact, he applied a traditional Urushi lacquer to the handles, giving them greater protection and a delicate dark hue. The yu kurosaki gekko knives are knives with a strong character that will find a place in the homes of all Japanese knife lovers!
