Sharpening the knife with one or two steps is decided by the degree of blunt tool. Step 1: Coarse grinding, used to repair the seriously damaged edge, suitable for the blunt knife. Hold the knife at an angle of 10 - 30 deg, grind the edge on the surface of the stone back and forth with gentle pressure, and sharpen 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: Fine grinding, a necessary step to eliminate burrs of the edge. Use more gentle pressure, repeat step 1, and repair the edge until smoothly and keenly. General speaking, use it once a week to keep your blade sharp.
