Honing realigns a knife's edge and should be done often, even every few uses, with a honing rod. Sharpening removes metal to create a new edge and is needed a few times a year for most home cooks. Whetstones give the most control and the best edge, pull-through sharpeners are quick and easy, and electric sharpeners are fast but remove more metal. Match the sharpening angle to your knife.
A sharp knife is safer than a dull one, because it needs less force and is less likely to slip.
Honing vs sharpening
| Honing | Sharpening | |
|---|---|---|
| What it does | Realigns the existing edge | Grinds a new edge |
| Removes metal? | Very little | Yes |
| Tool | Honing rod (steel or ceramic) | Whetstone, pull-through or electric sharpener |
| How often | Every few uses | A few times a year |
How to hone
- Hold the rod vertically, tip on a towel on the counter.
- Place the heel of the knife against the rod at your knife’s angle (about 15 to 20°).
- Draw the blade down and toward you, heel to tip.
- Alternate sides, 5 to 8 strokes each, with light pressure.
Sharpening options
| Tool | Pros | Cons |
|---|---|---|
| Whetstone | Best edge, full control | Takes practice |
| Pull-through | Quick, easy | Less precise, fixed angle |
| Electric | Fast | Removes more metal |
| Professional service | Expert results | Cost, time without knives |
Whetstone basics
- Soak or wet the stone as the maker directs.
- Hold the knife at a consistent angle.
- Sweep the blade across the stone, heel to tip, until you feel a slight burr along the edge.
- Repeat on the other side, then refine on a finer grit.
- Strop or hone lightly, and wash the knife.
Match the angle
Many German-style knives are sharpened around 15 to 20° per side; many Japanese-style knives around 10 to 15°. Check your knife maker’s guidance.
The tomato test
A sharp knife bites into tomato skin with no pressure. If it slides, hone; if honing doesn’t fix it, sharpen.
Common questions
How often should I sharpen my knives?
Most home cooks need to sharpen a few times a year, and hone regularly in between. If a knife slides off a tomato skin instead of biting in, it's time.
Does a honing steel sharpen a knife?
Not really. A honing rod straightens the edge so it cuts well again; sharpening grinds a new edge when honing no longer helps.
What grit whetstone should I use?
A combination stone around 1000/6000 grit covers most needs: 1000 for sharpening, 6000 for polishing. Use a coarser stone (around 400) for very dull or chipped knives.
