Sharpening Stones

The Apex of Sharpening: Naniwa 1000 Professional Stone For the craftsman who understands that the edge is everything, there is the Naniwa 1000 Professional Stone. This is not merely a tool for sharpening; it is the heart of a precision sharpening system, revered globally by master chefs, woodworkers, and knife enthusiasts for delivering an unparalleled sharpening experience. At the 1000-grit level, it is the quintessential workhorse—aggressively re-establishing a flawless primary bevel on a dull blade while leaving a refined, toothy edge ready for the most demanding cuts. The soul of this stone lies in its advanced magnesia-bonding process. This proprietary method creates a supremely dense yet friable surface, packed with a higher concentration of premium abrasive. The result is a sharpening sensation that must be felt to be believed: a swift, almost effortless cutting action with a smooth, velvety feedback that communicates the state of the edge directly to your hands. As you work, it generates a rich, uniform slurry that aids in polishing the steel, creating the beautiful, hazy kasumi finish prized on high-end Japanese cutlery. This is more than a purchase; it's an investment in the art of sharpening. Choose the Naniwa Professional when you seek not just a sharp knife, but mastery over the edge itself. Learn More

Unlock Flawless Edges with the Ultimate Sharpening Surface: The Naniwa Diamond Stone 1000 Step up to the pinnacle of sharpening technology with the Naniwa 1000 Grit Diamond Sharpening Stone. Precision-engineered in Japan for those who refuse to compromise on sharpness, this stone is the definitive tool for maintaining and restoring a perfect, razor-sharp edge. The 1000 grit is the ideal "workhorse" grade, expertly balanced to quickly erase dullness and establish a refined edge that is ready for use or further polishing. At its core lies a perfectly flat steel plate coated with high-density monocrystalline diamonds—the hardest and most durable abrasive available. This advanced construction gives it unparalleled cutting speed, allowing you to sharpen even the most challenging modern "super steels" (like S90V, ZDP-189, and Maxamet) and ceramics with remarkable ease. Unlike traditional whetstones, the Naniwa Diamond Stone will never dish, warp, or require flattening. It guarantees a perfectly true surface for the entire life of the stone, ensuring every pass contributes to a consistent, flawless bevel. For the discerning user, this isn't just a sharpener; it's a permanent upgrade to your entire sharpening system. Learn More

Size: (210x70x20 mm) (8.25x2.75x.80 in.)
Naniwa "Super Stones" require no soaking, just splash and go. The 1000 grit stone is used for establishing an edge on a dull knife. It will remove micro-pitting but any chips will require a more coarse stone. This is the average size used for sharpening a dull knife. For use on meats, you may want to continue sharpening with a higher grit but will work great on vegetables. Learn More

Naniwa’s Traditional Water Stones are specially designed for sharpening hard steels commonly found in woodworking tools and select specialty knives. This Hard Steel series runs parallel to Naniwa’s Standard Traditional Stones but is engineered for enhanced performance on tough steels. Featuring a harder binder, these stones provide a more aggressive sharpening action while minimizing wear, making them ideal for the unique demands of hard steel applications. 1000 Grit: This stone is a very popular grit choice because it starts to refine the edge. This stone is an excellent follow-up after using the 220 stone. If your edge isn't very worn, you don't need to start any coarser than this. Learn More
