A knife loses its sharpness when the fine tip of the cutting edge gets knocked slightly out of alignment. But how do you determine when your knife needs to be sharpened? Put it to the paper test.
Is it sharp? To determine if your knife needs to be sharpened, put it to the paper test:
1. Hold a folded, but not creased, sheet of newspaper by one end.
2. Lay the blade against the top edge at an angle and slice outward. If the knife fails to slice cleanly, try steeling it. If it still fails, it needs sharpening.
