Risam Sharpening Stone 3000/8000 Grit

High Grit Sharpening Stone 3000/8000 RISAM® 3000/8000 sharpening stone is polycrystalline, made of excellent quality corundum (Al2O3) and ensures excellent results. Used on high hardness knives and at a small angle between 8 ° - 20 °. Equipped with non-slip base for maximum safety during use. Not suitable for use on sharpened knives or grease blades, as it is used for grinding and not for sharpening. Hard / fine side: F3000 / F8000, J9000 / J20000 Instructions for use Soak the stone in water for 5 minutes and then place it on a firm base. The use of one side or the other depends on the size of the blade problem. STEP 1 Start by pushing the knife up and down, without much pressure. During the process, the angle between the knife and the stone should be between 8º and 20º. With proper use, you will repeat the above procedure in about 2 to 3 months. STEP 2 Repeat the same process with the fine side of the stone, applying less pressure this time. The fine side helps to eliminate chips and ensures a smooth and bright blade. Under normal circumstances, the use of the fine side is per month, or even shorter, depending on the use. STEP 3 Clean the knife with a cloth and the stone with a brush, to remove the shavings. Leave it outdoors until it is completely dry.
