*Please note: the handle is now walnut octagonal with a black pakka ferrule, not oval rosewood*
Designed by Oster Rob in Slovenia and Yoshida Hamono, the heart of the knives is made of ZDP-189 steel, which was selected because systematic testing has proven its superior qualities and long-lasting sharpness.
The steel is laminated with an external layer of softer stainless steel that makes it easier to care for and more durable. Such a blade remains sharp for a very long time, its softer external layer makes it easier to sharpen, and it also protects the core steel from external factors.
The Kuro-uchi finishing of the blade, which is untreated at the tip and has already developed dark patina, protects the blade and gives it a traditional Japanese look. The knife bears visible impressions of the hand-making process, which gives it a beautiful finish and also prevents food from sticking.
