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


Introducing
Artisan Crafter with Traditional Techniques
Knives we offer at Chef’s Edge are artisan-crafted in Japan — the product of traditional techniques, skilled hands, and a culture deeply rooted in blade-making excellence.
We work directly with blacksmiths and workshops across Japan to curate what we believe is the most exceptional range of Japanese kitchen knives in the world. Whether shaped in a small forge in Sanjo or hand-finished in Sakai, each piece reflects the care, precision, and performance that define true craftsmanship.
At Chef’s Edge, we exist to bring these tools — and their stories — into the hands of cooks who appreciate the difference.
