How to Use a Honing Steel Without Ruining Your Knife

A honing steel is the most misunderstood tool in the knife drawer. Plenty of people give the blade a dozen fast, clattering swipes because that's what they've seen on television, then wonder why the knife feels no better. Others avoid the rod entirely because they've heard it damages hard Japanese steel.

Both reactions come from the same gap: nobody explains what the rod is actually for. So here is the honest version — what honing does, how to do it properly on a hard VG10 or AUS-10 blade, and when to put the rod down and reach for a stone instead.

What a honing steel actually does

Every time you cut, the very tip of the edge — a band of steel only a few microns wide — gets pushed slightly out of line. It doesn't wear away; it folds over, like the corner of a page. The blade is still sharp, but the sharp part is no longer pointing where you're cutting. That's the dull, dragging feeling you get on a tomato skin a few weeks after sharpening.

A honing rod pushes that folded band back into line. It's a realignment, not a re-cut. Done regularly it can keep a knife feeling freshly sharpened for months.

One useful distinction: a smooth, polished steel rod is purely realigning. The diamond-coated rods we stock are mildly abrasive as well — the diamond grit removes a very small amount of metal alongside the realigning action, which is why they still bite on hard, low-flex Japanese steel where a smooth rod can skate. It also means they need a lighter touch, not a firmer one.

What a rod cannot do is rebuild an edge that has genuinely worn away, or repair a chip. For that you need to remove metal properly — see how to tell when a knife needs sharpening.

Honing steel vs whetstone: which do you need?

Most kitchens want both, doing different jobs at different intervals.

	Honing steel	Whetstone
What it does	Realigns a rolled edge	Removes metal to cut a new edge
How often	Every week or two of regular use	Every few months, or when honing stops helping
Time taken	Under 30 seconds	10–20 minutes with soaking
Fixes a chip?	No	Yes

If you only ever buy one, buy the stone — it can do everything the rod does and more. But the rod is the one you'll actually reach for on a Tuesday evening, and that consistency is what keeps a knife pleasant to use. We compare the two in more depth in whetstone vs honing steel.

How to use a honing steel, step by step

1. Set the rod tip-down on a board. Rest the tip on a chopping board or folded tea towel and hold the handle so the rod stands vertically. This is far safer and more consistent than waving the rod in mid-air, and it lets you watch the angle.
2. Set the angle. Lay the blade flat against the rod, then lift the spine until there's roughly the thickness of two stacked coins underneath — about 15°. See the correct angle for Japanese-steel knives if you want the detail.
3. Start at the heel. Place the part of the edge nearest the handle at the top of the rod, close to your hand.
4. Draw down and back in one motion. Sweep the blade downwards along the rod while simultaneously pulling it towards you, so the contact point travels from heel to tip as the blade travels from top to bottom. It should take about a second.
5. Alternate sides. Repeat on the other face of the rod. Keep the pressure light — the weight of the knife plus a little guidance is enough.
6. Stop at 4–6 strokes per side. More is not better. If the knife still drags after that, it needs sharpening rather than honing.
7. Wipe the blade. A quick pass with a dry cloth removes the fine metal dust before you cut food.

What angle should you hone a Japanese-steel knife at?

Around 15° per side. That is the angle our knives are ground to, and honing at a steeper angle simply rounds the very tip of the edge off — you'll feel it get worse, not better.

This is the single biggest difference between honing a Japanese-steel knife and honing a heavier European one. German-style knives are typically ground nearer 20° per side, and most honing advice online is written with those in mind. Use a 20° motion on a 15° edge and you're grinding a small flat where the sharp part used to be.

If you struggle to judge it by eye, the two-coin trick under the spine gets most people close enough. A little shallower is better than a little steeper.

Worth saying plainly: our knives are double-bevelled, so both sides get the same treatment. Single-bevel traditional blades are a different discipline and shouldn't be honed this way.

How often should you hone?

For a home kitchen, once every week or two of regular use is about right. Professional kitchens hone daily because their knives are working for eight hours at a stretch.

There's no need to be rigid about it. The better habit is to hone when the knife tells you to: when a ripe tomato skin resists the first press, or when the knife starts sliding off an onion instead of biting in. If you hone at that point, the edge comes straight back. If you wait until the knife feels properly blunt, honing won't be enough — see how often to sharpen a Japanese-steel knife.

One caveat specific to hard steel. VG10 and AUS-10 sit around 60–61 HRC, which is harder than most European kitchen steel. Hard steel holds its edge longer, so it needs honing less often — but it's also less springy, so a fold that's left too long can break off as a small chip rather than bending back. Little and often beats occasional and forceful.

Five mistakes that damage a hard blade

• Using a coarse ribbed butcher's steel. Those deep ridges are designed for softer, thicker blades. On a thin, hard edge they chew rather than realign. A fine or smooth rod — or a diamond rod used lightly — is the right tool.
• Pressing hard. Force bends the edge past straight and can snap the fold clean off. The weight of the knife is genuinely enough.
• Going too fast. Speed makes the angle wander, and a wandering angle rounds the edge. Slow, deliberate strokes beat a flashy blur every time.
• Honing instead of sharpening. If twenty strokes haven't helped, the edge is worn or chipped and no amount of rod work will fix it. Go to a whetstone.
• Honing the wrong knives. Serrated bread knives and single-bevel traditional blades should be left alone. So should a knife with a visible chip — it needs a stone first.

Our honing steels

Whetstone Sharpening Stones 400/1000 3000/8000	£59.99	When honing is no longer enough

If your knife is already past the point a rod can help, the stone is the answer rather than a second rod: our Whetstone Sharpening Stones 400/1000 3000/8000 (£59.99, rated 4.86 from 118 reviews) cover repair through to finishing in one double-sided pair.

Frequently asked questions

Does a honing steel actually sharpen a knife?

Not in the usual sense. A honing rod straightens the very tip of the edge where it has folded over during use, which makes the knife feel sharp again. A diamond-coated rod also removes a tiny amount of metal, so it does a little light sharpening — but it cannot rebuild a worn edge or take out a chip. That needs a whetstone.

What angle should I hold the knife at?

About 15° per side for Japanese-steel knives, which is the angle they are ground to. A quick guide is to lay the blade flat against the rod and then lift the spine by roughly the thickness of two stacked coins. Heavier European knives are usually nearer 20°, so don't copy their technique on a thinner Japanese-steel blade.

How many strokes should I use?

Four to six light strokes per side is plenty. Honing is about precision, not repetition — twenty rushed strokes at a wandering angle will leave the knife worse than five careful ones. If the edge still drags after six strokes a side, it needs sharpening rather than honing.

Can you use a honing steel on hard Japanese steel?

Yes, with a light touch and the right rod. VG10 and AUS-10 sit around 60–61 HRC, so the edge is harder and less springy than European kitchen steel. Use a fine or diamond rod rather than a coarse ribbed butcher's steel, keep the pressure to the weight of the knife, and hone little and often rather than occasionally and hard.

How often should I hone my knife?

Every week or two of regular home use is a good rhythm, and daily in a busy professional kitchen. In practice the knife tells you: when a ripe tomato skin resists the first press, or the blade starts sliding off an onion rather than biting in, it is time for thirty seconds on the rod.

Which knives should never be honed?

Serrated knives such as bread knives — the rod cannot reach between the teeth and will only damage the points. Single-bevel traditional blades are also a different discipline and should be maintained on a stone. And a knife with a visible chip needs the stone first, because honing will simply fold metal around the damage.
