The knives from Nogent *** have the great advantage of benefitting from the world exclusive Affidenté® technology, developed and refined by Nogent *** over many years. The secret of this technology is the micro-serration which requires no sharpening - with 4 tiny teeth per mm of blade, the serration is almost invisible to the naked eye and delivers superior slicing with a high level of control. Each blade is manufactured from high quality, carbon molybdenum stainless steel which is tempered to produce a very high level of hardness. After a first sharpening operation, achieved with an automated machine, each knife is ground by hand on both sides of the blade on a grindstone. A second additional operation is carried out to obtain the Affidenté® serration exclusive to Nogent ***.The knives are incredibly sharp, enabling the user to cut and slice effortlessly and safely. They are also very comfortable to use as there is no sense of the serration when cutting.
