¥4,590
ALTSTONE RIN #5000
[English ver.] Includes English manual
No Soaking Needed — High-Density Ceramic Whetstone "RIN"
Always ready to use. Thanks to its non-absorbent nature, "RIN" lets you start sharpening immediately—no soaking, no waiting.
■ セット内容 / Set Includes
・Whetstone (main stone)
・Nagura stone
・Compact anti-slip mat
【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.
【#5000 Grit — Smooth Finish with Enhanced Sharpness】Step up your edge with a fine 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 such as 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.
【How to Use】Use this fine finishing stone after a medium stone (around #1000). Keep the surface flat by dressing it with a flattening stone as needed for consistent results.
【Thorough Quality Control】Every stone undergoes double inspection—first by the manufacturer, then by us—so that only flawless products are shipped.
