Victorinox high carbon, stainless steel blades are hand finished in Switzerland by skilled craftsmen. A special tempering process is used to produce an edge that can be resharpened over and over again. Each Victorinox knife is stamped from a single sheet of metal. The blade is then hardened, tempered, ground, polished, etched and finished. The patented Fibrox handles are hygienic, dishwasher safe and slip-resistant.
