This Shapton Glass Stone, grit 4000 is perfect for smooth, even sharpening. Which is exactly what we're looking for from a high-quality sharpening stone. Contrary to what you might expect from the name, the glass doesn't do the sharpening. You sharpen on a high-quality Japanese water stone. A layer of tempered glass is attached to this to prevent bending. This stone is suitable for sharpening almost all types of knives. From outdoor knives to kitchen knives, from pocket knives to chisels. These stones really come into their own with hard steels in particular. This includes the modern powder steels you'll find in high-end pocket knives.
This sharpening stone really is splash & go. That means you don't have to submerge it in water before use. Simply sprinkle some water onto it and the sharpening can begin. It removes material quickly, so the sharpening process is quick and easy. This also means the stone doesn't wear out as fast. The glass plate ensures you can use the stone right to its limit, further increasing the lifespan of your sharpening stone. Even as the stone gets thinner after years of use,
the sharpening result remains very even. The sharpening particles, made from white aluminium oxide, are very uniform in their shape and size. The minuscule "scratches" you add to your edge with this stone are therefore very even. You won't find it causing larger scratches that are difficult to file away with a finer grit. Sharpening enthusiasts truly appreciate this. This Shapton Glass Stone is quite simply one of the best sharpening stones on the market.
