Konosuke Sumiiro SLD Gyuto 240mm Ebony

As our relationship with Nihei san has grown, we knew we wanted to work with him to create something new, and unique-to-Konosuke. Today, we are delighted to release our latest product in the MADEI series- the SUMIIRO.

The ‘SUMIIRO’ has a core of SLD, hardened up to 65 HRC, and is clad in Stainless steel. The toughness of Nihei’s forging, combined with this cladding results in an excellent ‘all-rounder’ of a blade; the edge can stand up to the rigors of a Professional kitchen, while the lack of reactivity can give you peace-of-mind that you don’t need to be wiping down the blade constantly. For the surface of the blade, Nihei went with a beautiful Kurouchi Nashiji. This rustic finish is a specialty passed down by his Master, which Nihei san worked hard to learn during his time apprenticing. Combined with the resiliency of the stainless cladding, this handsome finish looks great without much of the maintenance a soft-iron-cladding finish can demand.

Once this project had been finalized, and we could see the completed knife, we asked Nihei san what he would like to call it. After some thinking, he decided on the word ‘SUMIIRO’. The word ‘Sumiiro’ means “the color of India ink”, as is seen in Japanese hand-painted calligraphy.

So this is the Konosuke Madei ‘Sumiiro’. An SLD Kurouchi Nashiji gyuto, forged and sharpened by the very talented Nihei. We hope you will give us your honest impression!
