【Firm Type】
A hard-type stone that delivers reliable sharpening, balanced for both hardness and cutting performance.

【Made in Japan】
Japanese-made ceramic whetstone. We work with domestic factories to manage everything from planning to delivery, ensuring top quality at a reasonable price.

【#1000 Grit — Your Go-To for Everyday Sharpening】
This is the essential grit for general sharpening. A slightly dulled kitchen knife is easily revived with #1000, and many home cooks find it sufficient as a finishing stone. If you're buying your first whetstone, #1000 is the ideal choice.

【#3000 Grit — Smooth Finish with Enhanced Sharpness】
Step up your edge with a #3000 finishing stone. It's perfect for removing micro-scratches left by medium grits and gives your knife a noticeably sharper feel. Recommended for first-time finishers.

【High Abrasive Power】
Packed with high-density WA (white aluminum oxide) abrasives, it offers excellent metal removal. Even beginners can clearly feel the knife getting sharper as metal is shaved away.

■ Compatible Steels
Suitable for common household stainless steel knives and even high-hardness carbon steel (hagane) blades.
Note: Not compatible with non-metal blades such as ceramic, or special materials like titanium.

【Anti-Slip Mat Included】
Comes with a compact anti-slip mat so you can sharpen safely even on stainless kitchen countertops. The mat's rubber was carefully selected from dozens of options for maximum grip. Ideal for users without a dedicated whetstone base.

【Thorough Quality Control】
All stones undergo double inspection—first by the manufacturer, then by us—to ensure only flawless products are shipped.
