The Naniwa Advance Super Combination Stone is a high-quality dual-grit water stone for sharpening knives and tools, combining two grit levels in a single stone. This design makes it convenient to complete the entire sharpening process — from coarse metal removal to final edge refinement — using just one stone.
Stones from the Advance Super series are made from a high-density abrasive material. Before use, it is sufficient to simply wet the surface with water.
