Shapton Glass stone 3000HR by Shapton

Sharpening Stone Shapton GlassStone HR Grit #3000. The GlassStone series of sharpening stones uses a revolutionary design to provide great usability within a thin package formed from a combination of glass layers. The conventional image is that sharpening stones are large and heavy, but GlassStones are not only thin and light, but also strong, as layers of tempered glass are stuck together. GlassStones therefore have strong resistance to cracking or sudden breakage caused by external shocks such as being dropped. Micron class represents the coarseness, in another word, the size of the abrasive grains in a sharpening stone. The higher the number, the larger the grain size, in other words, the coarser the sharpening stone. Shapton stones do not need to be soaked except the very first time after purchase. We do recommend that on first use, you pre-soak the stone in water for five to six minutes to secure even smoother sharpening. Shapton stones are great at sharpening because of their high abrasive content - you can form an edge in no time. Shapton's unique bonding technology allows the abrasives to perform at an optimum level, resulting in long-lasting sharpening stones.
