An In depth look

Blade Type

The Petty knife, a quintessential tool in Japanese cuisine, is a smaller utility knife used for precise, delicate tasks. Often considered a smaller sibling to the chef's knife, it excels in hand-held tasks like peeling, trimming, and intricate cutting. Its versatility makes it an essential for detailed culinary work.

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, semi-stainless steel and will be robust and resistant to rust. While it will not rust quickly like pure carbon, it is still best practice to not leave this knife wet for extended periods as it's stain-less, not stain-none! A light patina (colouration and seasoning of the steel) will still form over time.
