Konosuke has created a new and beautiful line called Sumiiro. Konosuke Sumiiro has a core of SLD, hardened up to 65 HRC, and is clad in stainless steel. The toughness of Mr. Nihei’s forging, combined with this cladding results in an excellent "all-arounder" of a blade while the lack of reactivity can give you peace-of-mind that you don’t need to be wiping down the blade constantly.
The finish is stunning with a beautiful kurouchi nashiji finish. This handsome finish looks great without much of the maintenance a soft-iron-cladding finish can demand. "Sumiiro" means “the color of India ink,” as is seen in Japanese hand-painted calligraphy.
