Blade Type

The Santoku knife, a classic in Japanese kitchens, translates to "three virtues," symbolizing its proficiency in slicing, dicing, and mincing. With a shorter, versatile blade and a balanced design, it's ideal for a range of tasks, from cutting meat to chopping vegetables, making it a beloved all-purpose tool.

Steel Type

Japanese Blue Super Steel, an elite variant of the "Aogami" series, is a high-carbon steel alloyed with chromium, tungsten, and added vanadium. This composition enhances its wear resistance, edge retention, and overall toughness. It will still rust if left wet for too long, but not as quickly as any of the other carbon steels. Favored in fine knife crafting, Blue Super Steel is renowned for producing exceptionally sharp and durable Japanese knives.

Care Information

This knife is made from a high-carbon steel and as such, will require a little more care than a regular off-the-shelf knife. It must be dried shortly after use, as prolonged exposure to moisture can cause rust spots to appear. A very light coat of oil during storage also helps to prevent rust spots. A patina (colouration and seasoning of the steel) will occur with use.

Introducing

Yu Kurosaki

Yu Kurosaki has become one of Japan’s most celebrated blacksmiths — known for his bold aesthetic choices, cutting-edge techniques, and dedication to pushing the boundaries of traditional knifemaking. Beginning his journey in his teens and apprenticing for 12 years under Hiroshi Kato, Kurosaki established his own forge in 2014 and has since earned recognition from the Japanese government as the youngest ever to be named a Master Blacksmith.

His knives are instantly recognizable for their striking Tsuchime and Suminagashi finishes, thin grinds, and use of high-performance steels such as SG2, HAP40, and stainless-clad Blue Super. Kurosaki’s Fujin series, with its dramatic wind-patterned hammer finish, helped cement his reputation as a blacksmith who blends artistry and technical brilliance in equal measure.
