The best bunka in the world with gray handle.
HAP40 is an exceptional steel that has not been used for chef's knives for too long. It belongs to the group of powder metallurgical steels, which obtain a more uniform steel structure than cast steels by melting pure metal powder under pressure. Particularly noteworthy is the extreme hardness of the HAP40 steel used for this blade. Through a special heat treatment with salt baths, the steel achieves a hardness of HRC 65-67.
Currently, HAP40 is only processed by a few Japanese forges in the traditional way, so the supply of HAP40 blades is still very limited. We are therefore proud to offer our own HAP40 series. We have the Silverback HAP40 knives forged for us by specialists in and around Seki, Japan, according to our specifications and are pleased to be able to offer this series at attractive prices. Each knife in this series is engraved with the Silverback "銀 背" (Japanese for silverback) and is therefore unique and only available from us.
The HAP40 core of this Silverback Knives Nakiri is surrounded by a sheath steel made of 404 stainless steel. This is forged around the core steel using the San Mai method. The sheath steel has been machined so that the surface in the upper blade area has a hammered surface. This surface structure is called Tsuchime and serves on the one hand the optics, but at the same time food sticks less when cutting, because small air pockets between the blade and the cut material are created during cutting. The blade, which is very fine compared to other traditional Japanese knives, is often referred to as a laser blade. After hardening, the blade is ground on both sides and set in the Complite handle. This is made of high quality reinforced wood, resulting in excellent robustness and durability.
The Bunka has a blade length of 175 mm and has an inverted Tanto tip. An interesting feature of this knife is the slightly curved blade shape at the back of the blade. This geometry saves weight on the one hand, which improves the balance of the knife, and at the same time this blade back creates a dynamic look. The Bunka is an all-purpose knife and can be used for meat, fish, fruit and vegetables. The fine chopping of ginger or onions is just as feasible as coarse preparation work. Compared to the gyuto and santoku, which are also considered Japanese forms of Western chef's knives, the bunka has a concise tip. This blade tip can be beneficial for precise work such as cutting fish or incising rind. The high hardness of the steel allows for an extremely sharp blade that will stay with you for a long time. Look forward to your first paper test at home!
