Using Instruction:
Soak the stone in the water for 5 minutes and then put it on a steady surface such as a table or desk. Sharpening the knives with one or two steps is decided by the dullness of the blade.

Step 1: 3000 coarse grit is used to repair a very blunt edge and is suitable for dull knives.  Hold the knife at an angle of 10 - 30 ° and grind the edge on the surface of stone back and forth with gentle pressure until the edge sharpness meets your standards. 

 

After sharpening the tool it is recommended to hone the blade with 3000 coarse grinding after 6 months. Of course, this depends on the use of the blade and user frequency will vary.

Step 2: 8000 grit fine grinding is a necessary step to eliminate burrs on the edge.  Use more gentle pressure, repeat step 1, and repair the edge until it has a smooth and fine edge.

General speaking, use the 8000 grit once a week to keep your blade sharp.

Wipe the stone with a wet cloth or rinse it with water after sharpening the tool and then dry with a clean towel. Clean the stone surface with a soft brush and leave it in an open area to dry thoroughly before storing.
