Konosuke has created a new and beautiful line called the 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 blades are surfaced with beautiful kurouchi and nashiji finishes. 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 seen in Japanese hand-painted calligraphy.
