Naniwa Chosera 1K / 3K Whetstones with Leather Strop Bundle

Naniwa Chosera – 1000 / 3000 Grit Japanese Waterstone & K&S Leather Strop Sharpening Set

This sharpening set combines the speed and precision of Naniwa Chosera stones with the edge-refining performance of a K&S leather strop, creating a complete and highly effective system for maintaining razor-sharp kitchen knives.

The Naniwa Chosera stones are part of Naniwa’s premium Japanese Domestic Market (JDM) range and are widely regarded as some of the finest ceramic sharpening stones available. Designed for professionals and serious enthusiasts, they deliver fast cutting speed, excellent feedback, and consistent results, even under heavy daily use.

Sharing the same abrasive formulation as the Naniwa Professional (PRO) series—but in a thicker format and supplied with a Nagura stone—the Chosera stones offer superior value, durability, and longevity. Each stone includes a Nagura stone (67 × 49 × 25 mm) for creating a fine sharpening slurry during use.

Chosera stones are classified as splash-and-go, requiring only minimal water before sharpening. Many users find that a brief soak further enhances smoothness and feedback.

The K&S leather strop is used after stone sharpening to align and refine the edge, removing residual burrs and increasing sharpness and edge longevity. Stropping adds the final level of refinement that stones alone cannot achieve, making it an essential finishing step.
