The Umai splendid Japanese knife set features stainless steel blades with a beautiful dimpled and polished finish, honed to super-sharp edges. The dimpled surface is not only attractive, it helps keep food from sticking to the blade. They have stained wood handles for an upscale look. Set contains the classic four knives: yanagiba sushi knife, deba meat knife, nakiri vegetable knife and the gyutou chef’s all purpose knife. Clean with water and always wipe blade dry thoroughly with a soft cloth. Made in Japan.
