4 Steps to Your Sharpest Kitchen Knives Ever

Here’s how to maintain their edge.

One all-natural way to remove rust and other stubborn stains is to rub the blade with lemon and salt.

Few tools work as hard as kitchen knives. They slice, dice, chop, and mince -- until they don’t. To keep them sharp and ready for action, it’s important to give those steely blades the proper TLC.


1. Clean

Harsh detergents, heat, and jostling can wear on blades, even those labeled as dishwasher-safe. Chef Howie Velie, an associate dean at the Culinary Institute of America, in Hyde Park, New York, recommends placing yours flat in the sink, then tilting it a bit so its sharp edge presses gently against the surface. Clean it with a soft scrubby sponge, warm water, and mild dishwashing liquid. Dry it with a dish towel immediately to avoid water spots and bacterial growth.

2. Hone


Position steel and blade

Hold steel and knife as shown, with sharp edge of knife pointing away from you. Keeping sharp edge in contact with steel, tilt blade up 20 degrees.


Work on one side . . .

Drag blade from handle of steel out to its tip. At the same time, slide blade from heel to point against steel, so that steel has made contact with entire length of blade by the time you reach steel’s tip.


. . . then the other

With heel of blade under steel near its handle, tilt blade 20 degrees and slide sharp edge toward tip. At the same time, drag blade from heel to point. Repeat honing 10 times on each side.

3. Sharpen

Lubricate an oilstone with food-grade mineral oil. If you have a whetstone, submerge it in water until there are no visible air bubbles.


Position stone horizontally, coarse-side up, on a damp towel to prevent sliding. Lay upper portion of blade’s sharp edge against surface of stone, near its left end. Tilt blade 20 degrees, with sharp edge in contact with stone.


Slide sharp edge to right, across stone, applying pressure with help from your free hand, as shown. At the same time, move knife toward top edge of stone so that blade’s lower edge comes in contact with stone by the time you reach its right end. To work on blade’s other side, start at stone’s right end and tilt blade in opposite direction. Repeat sharpening 10 times on each side.

4. Store

Give knives their space! Keeping them loose in a drawer isn’t just dangerous for those reaching in; it’s a hazard for the blades: All that moving around can dull them and loosen them from their handles. Our test-kitchen team prefers to store knives in an in-drawer tray. You can also place them on a magnetic wall strip or in a knife block. If you choose the latter, says Velie, a wooden block (as opposed to stone or plastic) is gentlest on the blades.
