The use of the knife and personal preference determine how frequently it should be honed. As a general rule, it is advised to sharpen your knife after two to three uses or whenever you observe a decline in its cutting ability. Regular honing realigns the knife's edge, smoothes out any minor flaws or burrs that may appear during use, and keeps the blade razor-sharp. But keep in mind that honing by itself is not a replacement for sharpening. The blade will eventually need to be properly sharpened in order to maintain its edge. The quality of the knife, how frequently it is used, and individual preference will all influence how often you should sharpen your knives.
