Cleaning: The secret to an everlasting blade

Cleaning a high-quality knife is not just a matter of hygiene; it's an act of preservation. Poor maintenance can turn an exceptional blade into an oxidized and dull tool in just a few weeks.

1. The Arch-Nemesis: The Dishwasher

This is the point of no return for artisanal cutlery. Here's why you absolutely must avoid it:

- Chemical Corrosion: Dishwasher tablets are extremely aggressive. They attack steel (even stainless steel) and cause rust spots.

- Thermal Shock: Intense heat cycles cause the steel to expand and contract, which can weaken the edge and loosen the handle rivets.

- Mechanical Damage: Powerful water jets cause knives to move around and hit the basket or other utensils, destroying the blade's edge.

- Wood Destruction: If your handle is made of wood, the dishwasher will cause it to swell, crack, and then rot.

2. The Golden Rule: Hand - Soap - Drying

The professional method is simple and quick:

- Immediate Washing: Never leave your knives soaking in the sink. Acidic residues (lemon, tomato, onion) will attack the steel if left in prolonged contact.

- Lukewarm Water and Mild Soap: Use a non-abrasive sponge (soft side) to avoid scratching the blade's polish or Damascus pattern.

- Instant Drying: This is the most important step. Wipe your knife with a dry cloth immediately after washing. Stagnant moisture is the main cause of oxidation, even on so-called "stainless" steels.

3. Special Attention to Carbon Steels

If you own high-carbon blades (highly prized for their extreme sharpness), they are not protected against rust.

- The Patina: These blades will naturally change color and gray over time, which is normal.

- Oiling: If you don't use your knife for a few days, apply a drop of neutral oil (rapeseed or special camellia oil) to the blade to create a protective barrier against airborne moisture.

The Verdict: Take 30 seconds to hand wash and dry your knife after each use. This is the only way to ensure the edge remains razor-sharp and the handle retains its original shine.
