Tosa Blue 1 Kiritsuke 210

Tosa knives are known for their hammer forged technique known as Warikomi, where a glowing piece of cladding is split and the core cutting edge inserted, then forged together by hand. It is a complicated process that requires a high level of finesse and competence.

STEEL BREAKDOWN – Blue Steel is a traditional, high-carbon steel made by Hitachi Metals in Japan. It is the favourite steel of many knife makers and chefs across the world for it’s fantastic edge holding ability, toughness, and ease of sharpening. It contains few stainless elements, and as such will develop a patina, and develop rust spots if left wet after use. It requires a little more care and maintenance than something like VG-10 (Stainless Steel), so consider this when purchasing a Blue Steel knife as your first Japanese knife.
