Hatsukokoro—is more than just a name. It’s a quiet tribute to the deep respect Japan holds for craftsmanship, tradition, and the people behind the blades. Based in Amagasaki City since 2013, the company works closely with some of the most respected blacksmiths, sharpeners, and handle makers in Japan. Their house brand, Hatsukokoro, features knives crafted by highly skilled—but often undisclosed—artisans, letting the work speak for itself.
One of the standout lines in their collection is the Hikari Series, built from SLD semi-stainless steel. Originally developed by Hitachi for cutting other steels, SLD offers an edge that holds like high-carbon but with much easier maintenance. *It’s not fully stainless, so a quick wipe and dry after use—especially with acidic foods—is all it takes to keep it looking great.
What really sets the Hikari Series apart is its grind. These are true lasers—ultra-thin, lightweight, and precise, with a clean polish and a visible lamination line that adds to the visual appeal.
Kakushin can handle the blade-to-handle assembly for you at our shop. If you're new to the custom knife world and want to confirm the fit and sizing of a handle with a specific blade, feel free to reach out!
