東風 本霞 • 青二鋼

Kochi is one of Korin’s house brands designed by Japan’s most recognized Grand Master Sharpener Shouzou Mizuyama in collaboration with Korin’s Knife Master Chiharu Sugai. It took five years to find highly skilled craftsmen who could represent Korin and forge a knife based on the ideals of the two sharpeners. The Kochi knives are crafted with blue steel #2 which is a mixture of chromium, tungsten, and white steel #2. The addition of chromium and tungsten creates a harder steel, providing a good compromise for those who want a carbon knife with a longer edge retention than white steel.

For optimum user friendliness, the two sharpeners’ ideal knives are all hongasumi style blades that are easy to sharpen. These beautiful knives have an octagonal magnolia wood handle and come with a magnolia wooden knife cover to protect the blade when not in use.
