Tips
Place your whetstone on the non-slip rubber holder then position your knife at an angle to start sharpening the dull blade. Restore and sharpen your dull knife blades with the 400 rough grit stone. 
When using a whetstone, the blade should be held at a sharpening angle of about 8 -20 degrees.
Each person has an individual angle at which he sharpens the knife. The blade of the knife becomes sharper each time it is sharpened, so it is essential that a knife is always sharpened in the same manner and by the same person.
