Hatsukokoro is more than a brand name. It’s a quiet reminder to honor tradition, craft, and the people behind the work. Since 2013, this Amagasaki-based company has been bringing together some of Japan’s most respected blacksmiths, sharpeners, and handle makers, creating tools that reflect the heritage and spirit of Japanese bladesmithing.
A perfect example of that philosophy is the Kurogane series. These knives are rooted in tradition, made in regions like Tosa and Sakai—places with centuries-old forging culture. What sets Kurogane apart is its honest, rustic feel. The kurouchi finish is raw and unpolished by design, proudly bearing the marks of the forge. The blades are forged thicker than typical Japanese knives, giving them a sturdy, grounded presence in the hand. They’re intentionally left with a bit of heft and room to grow—easy to regrind, reprofile, and customize as they become your own.
No two Kurogane knives are exactly alike. You might notice slight variations from piece to piece: a subtle asymmetry here, a forge mark there. These aren’t flaws—they’re reminders that each knife passed through the hands of a real craftsperson, not a factory line.
If you're drawn to the clean, flawless look of machine-made blades, these might feel too raw. But if you appreciate tools with soul—ones that feel as though they’ve already lived a bit before arriving in your kitchen—the Kurogane series is a rare find.
Whether you're just starting your journey with handcrafted knives or looking to add a bit of honest character to your collection, Kurogane is a beautiful reflection of what makes traditional craftsmanship so special.
The Santoku shape, known for its balance and versatility, is a staple in many kitchens. Perfect for slicing meat, chopping vegetables, and mincing herbs, it’s a reliable everyday workhorse. Shorter and lighter than a Gyuto, it offers comfort and control, especially for those new to Japanese knives.
