Revolution is a series of fantastic knives from Mcusta / Zanmai with a very thin blade made of three layers of steel with a core steel of SPG2, a Japanese powder steel known for its excellent resistance to wear. The hardness level is 61 HRC, which provides a fantastic lasting sharpness. The smooth line between the side support steel and the core steel creates an incredibly beautiful blade, designed to resemble Japanese swords. The Revolution series has an ergonomic, soft and curved handle, which is different from many other models from Japanese Zanmai. The beautifully designed handle fits perfectly in the hand and provides a firm and steady grip. Kosantoku is ideal for both professional chefs and home cooks looking for high-quality tools. The length of the leaf is 15 cm.
