Our combination diamond sharpening stone of #360/#1000 granulation with a non-slip plastic base stand for safer sharpening, which prevents the stone from moving around, is a highly applicable sharpening tool that every sharpening enthusiast needs in their arsenal. It works with most steel types of various hardness, can repair the surface of other sharpening stones, and also makes a great gift.

Diamond sharpening stones are most suitable for the initial sharpening of very blunt or visibly damaged, chipped knives since diamond stones are very abrasive and will quickly remove steel. They are also used to change the geometry of the blade if needed. The #360 grit is used for repairing large chips or restoring basic sharpness. The #1000 grit of the diamond sharpening stone can be used for regular maintenance and honing of your knives, ensuring that the blade achieves fine cutting function. Higher grits are suitable for final, fine polishing – make sure to check them out at our store.

Due to its incredible abrasiveness, this diamond sharpening stone can also be used to flatten whetstones of higher granulations. The #360 grit can be used to flatten stones of grit #500 and higher. However, it is important that before flattening whetstones with a diamond sharpening stone, you let the to-be-flattened whetstone soak in water for at least half an hour.

The diamond sharpening stone has a wide non-slip plastic base for a better sharpening experience and improved safety of use. 

The main advantage of diamond stones over whetstones is that they will keep their shape even with prolonged use. They will remain flat and will not get thinner, ensuring long-term usability. However, diamond stones do not have such a smooth and fine grit as whetstones, so they cannot be used for the final stage of knife sharpening, or for polishing. Your home sharpening set would also not be complete without a leather strop for the final smoothing and removing the burr. If that is what you are looking for, check out the other sharpening sets on our store.

Important: Always splash some water on the diamond stone before sharpening.
This produces a slushy surface on top of the stone as the abrasive particles are released. This “slurry” is saturated with sharp particles, making sharpening easier and faster, while the removed metal particles immediately drain away. This means they can’t get caught in the stone and scratch the knife.
