This Shapton Pro Stone, murasaki is a very special sharpening stone with a grit size of 30,000. It's so fine that it almost feels silky soft. As with all Shapton Pro Stones, you can sharpen very quickly and evenly with this 30,000 stone. The sharpening stone is really made for the very last step in the sharpening process, so that even the last millimetre of the edge is absolutely razor-sharp. It's ideal for sharpening straight razor blades, for instance. Before you switch to this stone, you'll want to use the 12,000 stone if you're grinding harder steels. For softer steels, the 8,000 stone is more suitable. If you use this 30,000 stone correctly after that, the edge will be sharper than ever before.
With this super fine 30,000 stone in particular, it's really important to work as cleanly as possible. Especially if you've just sharpened on a coarser stone beforehand. Clean the knife/tool thoroughly before using the stone. The same goes for your hands and under your nails. This reduces the chance of you diminishing the fine surface of the stone.
Shapton Pro Stones
In Japan, these colourful Shapton Pro sharpening stones are also known as Shapton Ha-No-Kuromaku. They are Shapton's thickest sharpening stones, with a thickness of 15 mm. As befits Shapton, each stone is beautifully homogeneous in structure, with evenly distributed ceramic sharpening particles. This ensures a really even sharpening result. Because the stones are fairly hard, they quickly remove material and they take a long time to wear down.

How to use Shapton Pro Stones
Every Shapton Pro sharpening stone is splash & go: simply sprinkle a bit of water onto the stone and you can start sharpening. You'll notice that the stone removes material pretty quickly. This gives you speedy results, and also means the stone wears down less quickly. Do not submerge the stone in water. This doesn't do the stone any good! The same goes for exposure to high temperatures, boiling water or soapy water.
After use, clean the stone with water and leave it to dry. Don't try to speed up the drying process with a fan or heater - give the stone time to dry naturally. After it has dried completely, you can put it back in the corresponding storage box.
If used frequently, the stone will hollow out over time. A lapping plate can solve this problem in no time, leaving the stone as flat as a billiard cloth once again.
Multifunctional protective box
This Shapton Pro Stone comes in a purple plastic storage box, which matches the colour of the sharpening stone. The box isn't just useful for storing the stone - the top also has raised edges that the sharpening stone fits exactly in between. This means you can also use the box as a sharpening stone holder. The non-slip feet on the bottom mean that it won't slide while you're sharpening. Finally, there are ventilation holes on the bottom, so you can store the sharpening stone without any worries, even if the sharpening stone doesn't appear to be fully dry. These details make all the difference.
