■ 特長 (Key Features)
【Hard-Type Stone】Despite its hardness, “RIN” offers excellent blade contact without slipping. A perfect balance of hardness and grindability, suited for serious users.
【Made in Japan】Crafted in Japan with strict quality control. The most-used #1000 medium grit comes paired with a nagura stone for surface conditioning. From planning to shipping, all stages are managed in Japan to ensure both quality and value.
【#1000 Grit — The Essential Grit】This is the standard grit for routine maintenance. It easily restores slightly dulled knives, and for most home cooking, #1000 grit is all you need. Ideal for beginners purchasing their first whetstone.
【High Abrasive Power】Infused with a high concentration of white aluminum oxide (WA), this stone offers powerful sharpening. Even first-timers can instantly feel the steel being ground away.
【Compatible Steels】Sharpen stainless kitchen knives, high-hardness carbon steel knives, and more. Note: Not suitable for non-metal blades (e.g. ceramic), titanium, or other exotic alloys.
【Anti-Slip Mat Included】Includes a kitchen-grade rubber mat that prevents slipping even on stainless surfaces. Carefully selected from dozens of materials to ensure strong grip. You can start sharpening immediately—no base required.
【Double Inspected】Every stone is thoroughly checked both by the manufacturer and by us before shipping to ensure flawless quality.
