Knife care · Jacob Bech

A sharp knife is a looked-after knife.

Wash it by hand, dry it straight away, cut on wood, and keep the edge up with a strop and a diamond stone. That is the whole routine. Below is how Jacob does it in the workshop in Greve, and the stones he uses.

Every day

Six habits that keep the edge.

Stainless steel is not no-stain steel. Most damage to a good knife happens at the sink, not on the board.

After use

Wash by hand

Warm water and a drop of mild soap, right after cooking. Wipe from spine to edge, never along the edge.

Straight away

Dry it with a towel

Do not let it air-dry on the rack. Water left on the blade and the handle is where spots and cracks start.

Never

The dishwasher

Heat, salt and long soaking hurt both the steel and the wooden handle. Do not leave the knife lying in the sink either.

Acidic food

Wipe between cuts

Lemon, tomato and onion slowly etch the edge. A quick wipe on a kitchen towel while you work is enough.

The board

Cut on wood

End-grain oak is kindest to the edge. Glass, marble, stone and ceramic plates dull a knife in a few strokes.

Storage

Keep blades apart

A magnetic rack, a block or a blade guard. Loose in a drawer, the edge chips against other metal.

Sharpening

A dull knife is the dangerous one.

It needs more force, so it slips. You do not need a schedule to know when it is time. The knife tells you.

The tomato test

Rest the edge on a ripe tomato and draw it back once, no pressure. A sharp edge breaks the skin. If it slides, it is time for the strop.

The paper test

Slice down through a sheet of printer paper. One clean, quiet cut is sharp. Tearing or catching halfway means the stones.

The light test

Hold the edge towards a lamp and look straight down it. A sharp edge shows nothing. Small bright spots are rolled or worn places.

ToolWhat it doesHow oftenUse it on
Leather stropStraightens and polishes the edge. Takes no steel away.A few passes every weekEvery knife
Diamond stoneGrinds a new edge. Plated diamond sets it, resin-bonded diamond refines it.About once a month for daily cooksEvery knife, including 62 HRC VG10
Honing rodPushes a soft, rolled edge back into line.Before use, if you own oneSofter Western knives. Not needed for hard steel

The rhythm for a home cook

Cook most days? Strop every week and go to the stones once a month. The strop keeps the edge aligned; the stones bring it back when the strop stops helping.

Jacob's method

Three steps. Under five minutes.

Twenty years of water stones, natural stones, ceramics and jigs came down to this. Diamond cuts hard steel fast and stays flat, so the stones never need flattening or soaking.

  1. Set the edgePlated diamond stone. Both sides, steady angle, until you can feel a small burr along the whole edge.
  2. Refine itResin-bonded diamond stone. Lighter pressure, fewer passes, until the burr is almost gone.
  3. Finish on leatherThe strop, edge trailing, never leading. Stop when the paper test is one clean cut.

The angle. Jacob shows how to find it and hold it in the beginner video, with no guide or jig. After a few weeks of ten minutes a day, your hands remember it.

Wood

The handle and the board.

Oak handles

Never soak a wooden handle. If it starts to feel rough after a few months, sand it lightly with 1500 grit paper to lay the raised fibres down, then rub in a thin layer of beeswax and food-grade mineral oil.

End-grain oak board

Jacob cuts on end-grain oak. The fibres stand up, so the edge slips between them instead of hitting them. Oak is not too hard and is lightly acidic, which helps keep it clean.

Questions

What people ask Jacob.

My knife is stainless. Why are there spots?

Stainless steel resists rust, it does not make it impossible. Spots usually come from water or acidic food left on the blade, most often near the edge. Rub them off with a little soap and a soft cloth, dry the knife, and they rarely come back.

Can I sharpen a Damascus knife on these stones?

Yes. Only the core steel touches the stone; the Damascus layers sit above the edge. Our EX-ANIMO knives have a VG10 core at 62 HRC, which is exactly what diamond stones are made for.

Diamond stones or water stones?

Water stones are pleasant and slow, and they dish, so they need flattening. Plated diamond stones cut hard steel fast and stay flat; resin-bonded diamond gives the fine edge. That is why every set here is diamond.

Do I need a leather strop?

It is the difference between sharp and razor sharp, and it keeps you off the stones between sessions. Jacob ends every sharpening on the strop.

Should I get my knives sharpened by a professional?

You can, once or twice a year. But a knife is only as sharp as the last person who sharpened it, and a few weeks of ten minutes a day is enough to do it yourself, whenever the knife needs it.

Can I oil the blade?

A thin layer of neutral oil after drying helps if the knife will sit unused for a while. Use a paper towel, lay the knife flat, and keep away from the edge.
