Sharp edges need a steady hand and the right grit. Start with a coarse stone to wipe out any chips, then move to a finer grit until the bevel feels almost invisible. Keep the angle consistent – 20‑25 degrees is usually good – and wipe the blade on a leather strop for that final polish. And remember, a sharp blade is only useful if you can keep it that way, so finish with a quick test on a piece of paper or a glass of water.
