Spectacular knives, hand-made in Sakai, Japan by the famous Itsuo Doi. Featuring an octagonal urushi roasted and lacquered oak-wood handle, and a hammer-forged blade made of hard and resilient Blue Super (aogami #2) carbon steel with a rockwell hardness of approx. 61-63, these will be amazing performers that you will be thrilled to own and use! The edges are ground 50/50 so they are fine for right- or left-hand use. Even the packaging is superb, with beautiful premium boxes and inserts.
