RockStar

Shapton RockStar – Next-generation consistent sharpening stone

Shapton RockStar is a sharpening stone series introduced at the end of 2023, sharing many features with the popular Shapton Glass series. Both are made from high-quality WA white aluminum oxide and use the same bonding material. Although the manufacturer has not specified the differences in composition, RockStar clearly stands as its own product line.

One visible difference is thickness: RockStar stones are 10 mm thick (or even slightly more), whereas the abrasive surface of the Glass series is 5 mm and bonded to a glass base. RockStar stones have no glass base, so the entire stone can be used from start to finish.

RockStar’s greatest strength is its consistent feel: all stones have the same sharpening sensation – only the grit varies. This makes the series particularly logical and pleasant to use, unlike the Kuromaku series where the feel varies from stone to stone.

All RockStar stones are Splash and Go, meaning sharpening can begin immediately with just a small amount of water. If you prefer, you can soak the stone for 5 minutes, which softens the surface slightly and improves the feel. Long soaking is not recommended.

New stones often have a rough surface layer that should be removed before use. A light pass with a flattening stone is enough to smooth it out.
