After months of requests from customers looking for a quality Japanese bread knife at a more approachable price point, we finally managed to get our hands on a limited number of Hatsukokoro bread knives. As always, we couldn't resist taking a few a step further.
This particular knife was assembled here at Kakushin as a true 1 of 1 custom build, pairing Hatsukokoro's highly regarded 240mm bread knife blade with a custom handle crafted from natural olive wood and flowing blue epoxy. The warm, organic grain of the olive wood blends naturally into the translucent blue resin, creating the impression of water moving through wood. Elegant, distinctive, and impossible to reproduce exactly, this handle transforms an already excellent tool into a genuine one-of-a-kind piece.
Hatsukokoro has built its reputation by collaborating with some of Japan's most respected blacksmiths, sharpeners, and craftsmen, bringing traditional Japanese craftsmanship to kitchens around the world. While often associated with high-performance chef knives, the same attention to detail is evident in this deceptively simple bread knife.
The bread knife is often one of the most overlooked tools in the kitchen—until you experience one that is truly well made. The 240mm blade features aggressive, precision-ground serrations designed to grip and slice cleanly through crusty artisan loaves, baguettes, pastries, sandwiches, tomatoes, melons, and other delicate foods without crushing or tearing them apart.
What truly separates this knife from many conventional bread knives is its geometry. The spine begins thicker near the handle for rigidity and stability before gradually tapering toward an impressively thin cutting edge. This creates a blade that feels controlled and substantial in hand while gliding through food with remarkably little resistance. Less force, cleaner cuts, and greater precision are immediately noticeable from the first slice.
Crafted from DSR-1K6 stainless steel, the blade offers excellent corrosion resistance and straightforward maintenance, making it a practical everyday tool that requires no special care. Combined with the custom olive wood and blue epoxy handle, it becomes something much more than a bread knife—an everyday kitchen essential elevated into a collectible custom piece.
A unique custom configuration assembled entirely in-house at Kakushin. Once sold, this exact combination is gone forever.
