Santoku – The Japanese All-Rounder
The santoku is Japan’s most popular all-purpose kitchen knife. Its name means “three virtues,” referring to its ability to handle meat, fish and vegetables with equal ease. With a shorter, taller profile than a Western chef’s knife, it offers precision, control and everyday versatility. The flat edge excels at push-cutting and chopping, while the wide blade makes scooping and transferring ingredients effortless.

Kurouchi – Rustic Blacksmith’s Finish
Kurouchi is the dark, textured finish left on the blade after forging. It provides a degree of protection against oxidation while giving each knife a rugged, hand-forged character.
