Sharpening
Sharpening: one stone, one angle, one afternoon
Sharpening removes metal to make a new edge. Honing pushes a rolled edge back into line and removes almost none. Most kitchens need honing weekly and sharpening two or three times a year, and confusing the two is why people believe their knives will not take an edge.

Two different operations, and the equipment for each.
Start with a combination stone
The Amazon Basics 1000/6000 double-sided with an angle guide and a non-slip bamboo base. That is the complete beginner’s kit: 1000 to cut a new edge, 6000 to refine it, and a guide to hold an angle while your hands learn one.
Then learn the angle
Most European kitchen knives are ground around 20° per side and most Japanese ones around 15°, and some listings publish it — the Paudin santoku states 13°, the Sanmeiho states 12°. Match what the knife was ground at, or you are reshaping the bevel rather than sharpening it.
Hone between sharpenings
The Victorinox 20 cm (7.9 in) chromed steel with a medium-fine cut is the cheapest honing steel here. The Winzbacher is 39 cm (15.4 in) overall with a non-slip soft-touch handle and — the feature worth paying for — a finger guard. Honing is a repetitive stroke towards your own hand.
If you want more grits
The Keenbest is two stones at 17.8 × 5.6 × 2.8 cm (7 × 2.2 × 1.1 in) with four grits on a bamboo base with rubber feet.
If you will not use a stone
The Adoric three-stage — diamond rod, tungsten carbide, ceramic, with a removable sharpening head. It is not as good as a stone and it is far better than a blunt knife.
The one thing to remember
A honing steel does not sharpen. If a knife will not cut after honing, it needs a stone.
The questions that come in
Whetstone or pull-through?
A stone gives the best edge and takes practice. A pull-through is faster, removes metal at a fixed angle regardless of how your knife was ground, and is a perfectly reasonable choice if you will not otherwise sharpen at all. A blunt knife is more dangerous than either.
What grit do I need?
A 1000 grit does the sharpening; anything above 3000 polishes. A 1000/6000 combination stone covers a domestic kitchen completely, and the cheapest one on this site costs about eight euros.
How often should I hone?
Every few uses, and always before a big job. It takes ten seconds and it is what keeps a knife feeling sharp between actual sharpenings.
Honing or sharpening?
Honing straightens a rolled edge and should be frequent. Sharpening removes metal and is what you need when honing no longer restores the bite.
What should I buy first?
A single medium stone will sharpen most kitchen knives adequately. The technique matters far more than owning several grits.
What do beginners get wrong?
The angle. Changing it mid-stroke rounds the edge, and holding it steady is essentially the whole skill.
Are guided systems any good?
They hold the angle for you, which removes the hardest part of learning. You trade some flexibility for consistency.
Can I ruin a knife?
You can remove metal in the wrong places, which is why everyone should practice on a cheap knife first.
How often should I sharpen?
Hone often and sharpen when honing stops working. The interval depends entirely on the steel, the board and how much you cut.
