Shapton Rockstar #4000

The Shapton Rock Star 4000 is a fine grit stone designed for refining and polishing your edges. It's the perfect stone for touch-ups, as it quickly brings back the sharpness of your blade without removing too much material.

As with all Shapton stones, the Rockstar 4000 is a splash-and-go stone, meaning you can start sharpening after just a quick splash of water. However, Shapton recommends a 5-minute soak the first time you use the stone. After this initial soaking, the Rockstar 4000 will be ready for splash-and-go use for all your future sharpening sessions.

Dimensions: 210x70x10mm

❖ Shapton Rockstar vs Shapton Pro (Kuromaku)
The Shapton Kuromaku and Rockstar sharpening stones are both made from aluminum oxide abrasives bonded with a magnesia binder. While the materials used are similar, there is a slight variation in the "recipe" between the two lines. The Rock Star stones undergo a modified molding and pressing process, creating a slightly harder and finer sharpening feel compared to the Kuromaku series. Additionally, the RockStar stones are thinner (10mm) than the Kuromaku stones (15mm). Both lines deliver exceptional results, and the choice between them comes down to personal preferences and specific sharpening requirements. (As a side note, the Rockstar series offers a level of quality comparable to Shapton's renowned GlassStone series.)
