Low grits 240/800 combination whetstone.
The RISAM® sharpening stones are made from professional grade white corundum (Al2O3), corrosion-resistant, heat-resistant, with edges and corners clearly demarcated.
Ideal for sharpening Japanese knives, Damascus knives or other high hardness knives.
Equipped with silica gel non-slip base for safe sharpening.
The coarse side 240 grit grinds the dull edge in order to create a new bevel. The fine side 800 grit is ideal for finishing the edge. If looking for an ultra sharp bevel, higher grit stones are required.
1. Soak the stone in the water for 5 minutes, and then put it on a steady platform. Sharpening the knives with one or two steps is decided by the degree of blunt tool.
Step 1: 240 grit coarse grit, used to repair the dull edge.
Hold the knife at an angle of 10° - 20°, depending on the knife's angle and grind the edge on the surface of the stone back and forth with gentle pressure. Keep sharpening it until the edge is sharp enough.
After sharpening the tool, it needs to be honed with coarse grinding after half a year. Also depends on the specific situation.
Step 2: 800 grit is for the finer grinding, a necessary step to eliminate burrs of the edge.
Use more gentle pressure, repeat step 1, and repair the edge smoothly and keenly.
2.Wipe it with wet cloth or rinse it with water after sharpening the tool, and then dry it. Clean the stone surface with a soft brush and put it in the air to make it dry.
Generally speaking, use it once a month to keep your blade sharp.
