Otsuki Hamono Blue Super Kurouchi Bunka 160mm

The Bunka is your small/medium sized prep solution. If you prefer a slightly shorter blade length but still need to prep veggies and smaller cuts of meat, this is your stop. The angled "K-Tip" allows for finer tip work and can be used to sweep ingredients across the board so you don't dull your edge.

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.

Hand wash only, never put in a dishwasher. Dry immediately after washing. Store on a magnetic knife strip or in a saya. Sharpen on a whetstone when the blade dulls. Read our full maintenance guide for more information.
