Naniwa Medium Stone #1000 (Made in Japan)

Naniwa is a Japanese manufacturer with over 60 years of experience producing sharpening stones for both industrial and household use. The company also designs diamond tools and other abrasive materials, continuously innovating to meet the highest standards of sharpening performance.

In short—abrasion. It’s a vital process in both industry and craftsmanship, and Naniwa has mastered it through decades of dedication and expertise.

The Naniwa Medium Stone #1000 is an excellent starting stone for those new to sharpening or anyone looking for an affordable, reliable option from Naniwa. While it doesn’t cut as aggressively as the Naniwa Super Stone series, it remains a very capable performer for everyday sharpening. Unlike the Professional series, which are splash-and-go, the Medium Stone requires a soaking time of about 10 minutes before use.

This #1000 grit stone is also commonly used to create a kasumi finish on knives, making it ideal for both home cooks and professionals who appreciate traditional Japanese sharpening techniques.
