How to Sharpen a Knife Quickly and Get a Razor Edge: Mastering the Angle Is the Key

Sharpening is an everyday skill for restoring a dull blade to sharpness, whether it is a kitchen cleaver, a pair of scissors, or farm tools such as a sickle or a billhook; blades grow dull with prolonged use. Mastering the correct sharpening method not only makes the tool easier to use, but is also safer, because a dull blade requires more force and is actually more likely to slip and cut your hand.

Before sharpening, get your tools ready. The most commonly used is a whetstone, generally available in coarse and fine grits. The coarse grit is used to repair a noticeably dull edge or one with small nicks, while the fine grit is used for the finishing pass to hone the edge. Before sharpening, soak the whetstone in water first, which lubricates and cools it and also reduces stone grit sticking to the blade.

The angle is the most critical thing when sharpening. For a kitchen cleaver, keep the blade at an angle of roughly ten-odd to twenty degrees to the whetstone, hold the blade steady with both hands, and push the edge along the stone surface from the heel of the blade to the tip, alternating between the two sides and keeping the number of strokes as even as possible to avoid sharpening it unevenly. After the coarse grit, switch to the fine whetstone and give it a few light passes; the edge will be even smoother and sharper.

When you are done, rinse the knife clean with water, wipe off the moisture, and if necessary apply a thin layer of cooking oil to prevent rust. Day-to-day care matters just as much: wash and dry the knife promptly after use, and do not leave it soaking in water for long periods or in contact with foods high in salt. If the edge is only slightly dull, a few light strokes with a honing rod in one direction will quickly restore sharpness, so you do not have to bring out the whetstone every time.
