Nenohi applies the skills and techniques of the traditional Japanese knives to the Western knives. Great attention to detail in every step of the production process. Much of the process is done by hand. All knives are also thoroughly inspected before they go out the door. The colored handles are a feast for the eyes and stand on a pedestal in the professional kitchen. The Premium series is recognized and admired by top chefs around the world. Each handle is handmade and unique. No handle is exactly the same or of exactly the same color.
