Hold the knife so that the blade touches the whetstone at an angle of 10-15 degrees. Then, pressing the blade lightly, move it along the stone, pushing the knife away from you and towards you with uniform movements, all the time maintaining a constant angle of inclination. 3. Repeat on both sides of the blade until the entire edge is sharp and there are no burrs anywhere. 4. Wet powder is released during sharpening.
