Hatsukokoro, meaning “don’t forget your original intention,” is more than just a name—it’s a guiding principle rooted in respect for traditional craft. Since 2013, this Amagasaki-based company has been working to connect Japan’s finest blacksmiths, sharpeners, and handle makers with cooks around the world. And one of the best examples of that mission in action is their Kurogane series.
The Kurogane series is all about delivering the essence of Japanese hand-forging at an approachable price. These knives are crafted in historic blacksmithing regions like Tosa and Sakai, known for producing blades with soul and strength. Built for those who value performance over polish, the Kurogane knives offer a thicker, more robust grind and a rustic kurouchi finish that proudly showcases their handmade nature.
These aren’t mass-produced, machine-finished blades. They’re forged, shaped, and sharpened by skilled hands—so you may notice small quirks from knife to knife: slight variations in the length, grind, or finish, or subtle marks left behind during the process. These details are completely normal and part of what makes each knife in the Kurogane line feel unique and authentic.
If you’re looking for a cheap knife that looks “perfect” out of the box, this probably isn’t the series for you. But if you want a hardworking tool with character, one that’s built with real intention and will serve you for years, the Kurogane series is an unbeatable value.
Whether you're a home cook building your first quality setup or a chef in need of something reliable and unpretentious, Kurogane offers a beautiful balance between tradition, performance, and price.
Don’t let the size fool you—Ko-Bunkas pack a punch. With their compact, angular blade and lightweight feel, they’re perfect for precision work like garlic, shallots, herbs, and small fruit or veg. Think of it as your go-to for those quick kitchen tasks where control matters more than size. Sharp, nimble, and fun to use… this little knife might just become your new favourite.
