When sharpening a knife with the help of a whetstone, the surface of the swan wears out unevenly. The screed is designed to level the surface of the whetstone before sharpening to ensure the highest possible quality sharpening result.

The waterfall screed has a coarse surface (#60). Before starting leveling, put the leveling whetstone in the water for a few minutes. If desired, you can draw diagonal crosses with a regular pencil on the surface of the stone. The stone is leveled when the pencil lines are lost in the process of leveling the stone.
