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 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 (coloration and seasoning of the steel) will occur with use.


Introducing
Hatsukokoro
Based in Amagasaki, Hatsukokoro partners closely with a wide network of skilled Japanese blacksmiths (Think Yoshikane, Myojin, Yauji and many more) and manufacturers to create an expansive range of kitchen knives. Their approach is rooted in collaboration — drawing on the strengths of various makers across Japan to develop collections that span from accessible entry-level pieces to exceptional high-performance tools.
