Shapton RockStar 320 Grit Sharpening Stone (White Alumina – WA)
The Shapton RockStar series is designed for fast, efficient sharpening with excellent feedback and durability. These stones feature a high abrasive content that cuts quickly, allowing you to form an edge in minimal time while maintaining excellent control.
The 320 grit RockStar is ideal for repair work, thinning, and setting a new bevel on dull or damaged knives. It removes material efficiently without feeling overly aggressive, making it a dependable coarse stone for both professionals and serious home sharpeners.
Unlike traditional soaking stones, Shapton RockStar stones are splash-and-go. Simply add water and start sharpening immediately. The stone’s advanced bonding technology helps regulate abrasive release, reducing wear and ensuring consistent performance over time.
The RockStar series features a solid 10 mm thickness. Compared to the thicker Kuromaku line, RockStar stones offer a lighter, more compact profile while preserving Shapton’s renowned sharpening speed and precision.
Abrasive Type: White Alumina (WA) – a refined aluminum oxide abrasive known for clean cutting action and balanced wear, especially well-suited for carbon and stainless steels.
Care Instructions: Do not soak this stone for extended periods. Splash with water only. After use, wipe dry and allow it to air dry naturally at room temperature. Avoid direct sunlight, wind, heaters, hot water, detergents, dishwashers, or dryers. Rapid temperature changes or forced drying may cause cracking.
