A practical foundation for everyday sharpening, the Naniwa Combination Sharpening Stone brings two essential grits into a single, space-efficient form—built for consistency, ease of use, and reliable results. Each stone pairs a medium grit for establishing and refining the edge with a finer grit for honing and finishing. The abrasive is engineered for balanced cutting speed and control, offering clear feedback as you work—responsive enough for touch-ups, yet capable of restoring a tired edge with patience. Designed to be used with water, the stone absorbs quickly and maintains a smooth, even surface throughout sharpening. The dual-sided construction is precisely bonded for durability, while the overall form remains compact and easy to store, making it well-suited for both home cooks and professional environments where efficiency matters. Straightforward, dependable, and thoughtfully made—everything you need to keep your knives in working condition, without excess. This is a great "gateway" stone. Perfect for someone just starting out in sharpening. Makes a great gift. Made in Vietnam. Dimensions 185mm x 65mm x 28mm Material Clay Based Use Everyday maintenance
