Shapton Rock Star Japanese Whetstone 60315, 320-grit

A Japanese whetstone to sharpen your blades

The Shapton Rockstar 60315 320-grit Japanese sharpening stoneis designed for sharpening tasks that require relatively heavy material removal. It features the coarsest grit in the Rock Star line, making it ideal for restoring a damaged edge, correcting a particularly dull blade, or adjusting its sharpening angle.

Its composition of white aluminum oxide (WA), a high-quality synthetic ceramic abrasive, ensures consistent action on the steel. Its precise 40-micron grain size allows for precise work on the cutting edge, while its durable structure minimizes wear on the stone over time.

This ceramic sharpening stone offers several advantages:

• Effective abrasion: its 320-grit finish allows you to restore edges that require sharpening
• Good wear resistance: its composition ensures consistent performance and long-lasting use
• Comfortable working surface: Its dimensions of 21 x 7 cm facilitate sharpening movements on blades of various lengths
• 1 cm thick: Its entirely abrasive construction allows you to utilize the stone’s full effective thickness

This wet-sharpening stone is suitablefor both knife enthusiasts and professionals looking to maintain or restore their cutting tools.

Please note: its coarse grit is intended for restoration; to achieve a finer, cleaner edge, continue sharpening with a stone of a finer grit—such as 1000—followed by a finishing stone depending on the desired result.

How to Use and Care for Your Water-Whetstone?

When using it for the first time, soak the Shapton Japanese stone for 5 to 6 minutes. For subsequent uses, moisten its surface and add water regularly while sharpening. Place it on a stable, non-slip surface.

After use, clean it with water, then let it air dry at room temperature. Avoid prolonged soaking, detergents, heat sources, and direct sunlight. A suitable dressing stone helps maintain a flat and effective surface.
