Blade Type

A paring knife, sometimes also known as a petty knife, is a small yet versatile tool, ideal for precise culinary tasks. Traditionally used for peeling, shaping, and delicate cutting, its compact size and sharp edge allow for meticulous control, making it essential for detailed work in fruits, vegetables, and garnishes.

Steel Type

Japanese Blue Steel #2, or "Aogami" #2, is a revered high-carbon steel alloyed with low amounts of chromium and tungsten. It strikes an excellent balance between durability, edge retention, and ease of sharpening. Slightly more ductile than Blue #1, it's widely used in crafting traditional Japanese knives, beloved by chefs for its resilience and sharpness, albeit is slightly softer than Blue 1.

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

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.

This thing IS THE BUSINESS!

Words can't explain how amazing this knife is to use and gaze at! It's my second bunka and my go to knife for everyday prep. Gyuto's aren't getting a look in at the moment. I LOVE it. Thanks Chefs Edge 👊🏽

Super Thin Bevels

The bevels being so thin makes it easy to achieve a crazy sharp edge and cut dense vegetables rather than splitting them. The kiritsuke tip also makes precise cuts such as on garlic possible. A pleasure to use

Great product, great service

Very happy with my purchase. First time customer, ordered and received a knife that had a chip which occurred during shipment. The staff at Chefs Edge were very prompt in communication and really helpful in resolving the matter. They sent out a new knife and arrived in time for a birthday. The knife itself is great quality and looks better than the photos. Overall, very happy and will be a return customer!

Fantastic knife with beautifully curated handle

Got this as a gift for one of my younger cooks who has been going above and beyond this year. Not only is the caretaking aspect of high carbon steels such as shirogami a great teacher for any future knives they may own, but its such a beautiful tsuchime finish with a fantastic grind that I found myself drooling over it aswell. 10/10 recommend not only Tsunehisa as a maker but Chefs Edge as a curator and purveyor of immaculate kitchen knives.
