Shapton Glass Stone: HR 30000 Grit

Shapton Glass Stones are known for their exceptional quality, durability and ease of use. Unlike other waterstones, Shapton Glass Stones do not need to be soaked in water before use - simply wet the surface and begin honing your blade.Shapton sharpening stones are made with finely graded ceramic cutting media that requires less flattening and lasts 4-5 times longer than most water stones. The abrasives in the glass stones are also extremely uniform, meaning the abrasive encountered with the first pass of a blade will be the same as the 5000th pass.Each stone is comprised of a 5mm tempered glass backing plate fused to a 5mm thick stone. The #30000 grit stone has a particle size of 0.49 microns and is ideal for putting an ultra sharp edge on a straight razor. Although it's not an essential stone, we do recommend using it after the #16000 grit stone if you like a really sharp edge. We recommend using the Shapton Stone Holder to hold the stone in place when in use.
