Stand the rod upright with its tip on a folded towel, set the heel of your knife against the top of the rod at 15 to 20 degrees, and draw the blade down and back toward you so the whole edge crosses the rod. Do that four to eight times a side, alternating, with no more pressure than the weight of the knife. If the knife still won't bite a tomato after that, honing isn't the fix; it needs sharpening.
What a honing rod does (and doesn't)
A kitchen edge is a strip of steel thinner than a hair. Cutting against a board dulls its very tip, so after a week of cooking the knife feels dull. The usual explanation is that the edge leans over and the rod pushes it back upright; America's Test Kitchen calls the name "sharpening steel" a misnomer on that basis. Electron micrographs published by Science of Sharp show something different: steel and ceramic rods both restore the edge by forming a tiny micro-bevel at the apex, which takes off a sliver of metal. That's why honing works for weeks and then stops, once the micro-bevel has grown too wide.
Rods differ in how much they also abrade:
| Rod | What it does to the edge | Best for |
|---|---|---|
| Steel (smooth or ribbed) | Hones a tiny micro-bevel; ribbed steels scrape a little more | Softer German-style stainless |
| Ceramic | Hones a micro-bevel and removes a very fine layer | Most knives, including harder Japanese blades |
| Diamond-coated | Removes metal fast, like a coarse stone | Very dull knives, occasional use only |
Which one to own is its own question; our ceramic vs steel honing rod comparison covers it. The technique below is the same for all three.
The safe method: rod tip-down on the counter
This is the method America's Test Kitchen and Knife Aid both recommend for home cooks, because the blade only ever moves down and away from the hand holding the rod.
- Fold a damp kitchen towel on the counter or a cutting board and stand the rod on it, tip down, handle up. Made In uses the towel for the same reason: the tip can't skate.
- Set the heel of the knife (the part nearest the handle) against the rod just below the guard, edge pointing down.
- Tilt the spine away from the rod until the blade sits at 15 to 20 degrees. See finding the angle below if you've never done this.
- Draw the knife down the rod and back toward you in one smooth stroke, so the contact point slides from heel to tip. The tip should leave the rod near the towel.
- Switch to the other side of the rod and do the same stroke with the other face of the blade against it.
- Alternate sides for four to eight strokes each. Then wipe the blade with a damp cloth; Chef's Armoury points out that steeling leaves fine metal filings on the edge.
Pressure is where most people go wrong. America's Test Kitchen's cue is the best one we've seen: a harsh rasp means you're pressing too hard; a quiet, light ring means the stroke is right. Move the knife, not the rod, and never bang the heel of the knife into the guard at the top.
Finding 15 or 20 degrees without a protractor
Hold the blade straight out from the rod: that's 90 degrees. Halve it to 45. Halve it again to about 22. For most German knives, stop there and come down a hair, to 20. For a Japanese or thin modern knife, go about a third lower again, to 15. Wusthof owners can find matching steels in our best honing steel for Wusthof knives.
A second check is spine height. With the blade flat against the rod, lift the spine. On a chef's knife about 50 mm (2 in) tall at the heel, 15 degrees puts the spine roughly 13 mm off the rod and 20 degrees about 17 mm. Our angle calculator does this math for any blade width.
| Knife | Hone at | Why |
|---|---|---|
| Older German knives (10+ years) | about 20° | America's Test Kitchen: older Western knives are likely 20 |
| Current Wüsthof and Zwilling | about 15° | Both now list thinner edges; see the Wüsthof and Zwilling pages |
| Japanese double-bevel (Shun, Global, Miyabi) | 15° or lower, ceramic rod only | Harder steel chips on ridged steels; Shun lists 16° |
| Single-bevel Japanese (deba, yanagiba) | don't hone | Chef's Armoury: never steel a chisel-edged blade |
| Serrated bread knife | skip the rod | Use a tapered rod in each scallop instead; see serrated knives |

The chef's method (rod in the air)
You've seen it on cooking shows: rod held up like a sword, knife flicking down both sides. Chef's Armoury teaches a slow version of it, with knife and rod meeting in an inverted V and the heel starting about 2 cm from the rod's tip. It's faster once you're good. It also puts the edge moving toward the hand on the handle, which is why we don't suggest it to anyone still learning the angle. If you try it, go slowly, keep that hand behind the guard, and use the same light pressure.
Hone, strop or sharpen? Read the symptom
| What you notice | Likely cause | Fix |
|---|---|---|
| Slips on tomato skin, fine yesterday | Lightly dulled edge | Hone, 4 to 8 strokes a side |
| Catches paper in one spot only | A rolled or nicked section | Hone; if the spot stays, sharpen |
| Cuts, but feels "slick" with no bite | Polished edge with a little burr | Ceramic rod or a few passes on a strop |
| Still dull after 8 strokes a side | Rounded edge, metal worn away | Sharpen on a stone or sharpener |
| Visible chips or a shiny line along the edge | Damage or a flat, worn apex | Sharpen, starting on a coarse grit |
The quickest test is America's Test Kitchen's paper slice: hold a sheet of printer paper by one corner and slice down from heel to tip. Clean cut, you're done. Tearing after honing means it's time to sharpen. How often that comes around depends on how much you cook; our how often to sharpen knives schedule has the numbers.
Rods worth owning
Buy a rod at least as long as your longest blade, which Chef's Armoury also recommends; a 10-inch rod covers an 8-inch chef's knife, and a 12-inch rod covers everything up to a slicer.
- For German-style knives on a budget, the Utopia Kitchen 12-inch honing rod is carbon steel plated with nickel-chrome and has a non-slip rubber base, per its listing.
- The Henckels sharpening steel and the Wüsthof 9-inch honing steel are the brand-matched steels for those knives.
- For harder Japanese knives, a fine ceramic rod such as the Work Sharp kitchen ceramic honing rod or the Green Elephant 1500-grit ceramic rod.
We compare seven of them in the best honing rod guide, and the honing rod vs whetstone page explains why you'll want both eventually.
Keeping the rod working
Wipe a steel rod dry after use and store it hanging or in a block. Ceramic rods slowly turn gray as steel particles load the surface; scrub them with a damp melamine sponge or a little powdered cleanser and they cut like new. Don't drop a ceramic rod on tile. And once a diamond rod's coating wears smooth in the middle, it's done. If you want a diamond rod, see our best diamond honing rod guide.
