You should treat your sharpener almost as carefully as you treat your blade. If the surface gets damaged that means it’s uneven, which can damage or groove your blade. Always wrap your stone in cloth before storing. If you used oil, make sure there’s still a layer of it coating the stone before you pack it away. If you used a water- or petroleum-based oil, wash your stone with soap and water before stowing it. If you see streaks or filings on your blade, be sure to clean the surface until it’s smooth and spotless. Never use an abrasive brush on your stone. If you must clean it heavily, a soft-bristled toothbrush, or even your finger is enough.

Diamond sharpening stones are sharpening stones coated in micro-diamonds. What’s inside the “stone” isn’t necessarily a chunk of rock. It could be metal or a composite stone manufactured mechanically. Diamond is one of the hardest substances on Earth. By coating a stone in diamond powder, it ensures you’ll be able to sharpen even the strongest blade, and the porous surface provides an escape route for filings that come off your blade. This keeps gunk from building up on the stone and hampering its effectiveness. DMT sharpening stones are some of the most popular of diamond sharpening stones.
There are several choices, but few as universally relied upon as the low-tech sharpening stone. Diamond stones, which have a very fine grit, are used on knives that only need touched up. For duller blades, approach it much like you’re using sandpaper on a block of wood: coarse-grit stones first (grits of 400 or less); then progressively finer ones (600 and above). For a serrated blade, you’re going to need a cone-shaped taper sharpener which will be made of the same material as a regular stone. For big tools: sharpening pads. Some enthusiasts swear by using oil to sharpen their blades, others go with water, or — in a pinch — saliva.
