  • Naniwa Super Stone #12,000 Grit S2-491
  • Super Fine grade stone for final polishing stage
  • Made from high-quality grit and softer resin
  • Light soaking required for a few minutes
  • Resin bonded with White Aluminium Oxide for premium cutting power

The Naniwa Super Stone #12,000 Grit S2-491 is a high-quality whetstone designed for the final polishing stage of sharpening. This Super Fine grade stone offers a high polishing effect and maintains its flatness for a long time.

The Super Stone series from Naniwa Abrasives is made from the same high-quality grit as the Naniwa Professional series but at a more budget-friendly price. These stones are made from a softer resin with slightly less grit, making them a great option for those seeking excellent results on a budget.

The Super Stones require light soaking for a few minutes before use. They are not extremely thirsty and only need a brief soak to be ready for sharpening. During use, an occasional splash of water keeps the stone working smoothly. It is important to avoid storing the stone in water to maintain its quality.

The stone is resin bonded with White Aluminium Oxide, providing premium cutting power and exceptional performance.

The Naniwa Super Stone series of stones may develop a dish after frequent usage. To maintain the stones and keep the surface flat for a longer lifespan, we recommend using a lapping plate. Consider options such as the Jende Industries Glass Lapping Plate, Shapton Diamond Glass Lapping Plate, or the Shapton NAORU cast iron lapping system for this purpose.
