The Shapton Glass Stone Seven are stunning Japanese sharpening stones. Compared to what you might expect from this name, you don't sharpen on glass. You sharpen on a top-quality, Japanese water stone. This stone is placed on a layer of tempered glass to make sure it won't bend. The stones can be used to sharpen almost any type of knife. From outdoor knives to kitchen knives and from pocket knives to chisels. These stones especially excel at sharpening hard types of steel. Think of modern types of powdered steel you often come across in pocket knives in the higher segment.
The stones look a lot like the 'regular' Glass Stones. With these stones you also quickly remove a lot of material. The difference can be found in the size of the stones and the thickness of the layer of sharpening particles. That thickness is namely 7 mm, which is 2 mm more than the HR and HC Glass Stones. This is also where the Shapton Glass Stone Seven got its name from.
These sharpening stones are truly splash & go. This means that you don't need to pre-soak them. You sprinkle them with some water and start sharpening. They quickly remove material, so sharpening is quick. As such you are quickly left with sharp knives, and a stone that doesn't wear out as fast. To extend the life the glass layer ensures that you can use the stones to their full extent. Even if the stones have gotten thinner after years of use.
The sharpening result is very even. The sharpening particles, made from white aluminium oxide, are incredibly uniform in terms of size and shape. The miniscule 'scratches' you add to your edge with your stone are therefore very even. You won't quickly come across a larger scratch that is hard to remove with a finer grain. Sharpening enthusiasts all across the world truly appreciate this. These Shapton Glass Stones simply belong amongst the best sharpening stones on the market.
Because of their size you can easily take the Shapton Glass Stone Seven sharpening stones with you on the road. There is also a Shapton sharpening stone holder when you are looking for a little more control. The holder is made to fit the Shapton Glass Stone Seven sharpening stones. The length of the holder and stones are perfectly aligned to make sure the stones are nicely secured. With the sharpening stone holder you slightly lift the stones. As such you have more room for your fingers making the sharpening process a little more comfortable. Because of the non-slip feet the holder won't slide during use. If you are experienced enough you can, of course, also sharpen without the holder.
The stones are incredibly wear and tear resistant but can become hollow with intensive use. This could affect the sharpening results. That is why Shapton recommends using the Glass Stone Seven diamond-coating lapping stone to keep your stones nice and flat.
