How to sharpen a knife using the right method
Choosing the right sharpener according to your knife's condition
- Whetstone: Very precise tool, professional results.
- Electric sharpener: Fast and convenient, constant guided angle.
- Compact manual sharpener: Ideal for small, regular maintenance.
- Sharpening steel: Excellent for quickly realigning the edge after each cut.
Stone sharpening, angles and step-by-step techniques
A 20-degree angle is often recommended for European models. Start by immersing your stone in water for about 15 minutes. Maintain a constant angle while gliding the blade over the stone, from base to tip.
| Knife type | Recommended angle | Stone grit |
| Japanese knives | 12-15 degrees | 1000-2000 |
| European knives | 15-25 degrees | 800-1000 |
| All-purpose knives | 15-20 degrees | 1000 |
| Chef's knives | 15 degrees | 1000-1200 |
Daily maintenance and post-sharpening check
After each sharpening, clean the blade with a damp cloth and dry it thoroughly. Store your kitchen knives in a wooden block and always prioritize hand washing.
FREQUENTLY ASKED QUESTIONS
WHAT IS THE BEST METHOD TO SHARPEN A KNIFE WITHOUT DEDICATED TOOLS?
You can sharpen your knife by rubbing its blade against the back of another. Maintain an angle of about 20 degrees to restore a clean edge. This technique does not replace the use of a whetstone or a professional sharpener.
HOW OFTEN SHOULD KNIVES BE SHARPENED?
For standard domestic use, sharpening your knife once a year with a stone is usually sufficient. Regular maintenance with a sharpening steel helps realign the edge without removing material.
HOW TO CHECK IF A KNIFE IS PROPERLY SHARPENED?
The paper test is reliable: a well-sharpened knife should cut through it cleanly. The blade should also cut through a tomato skin without tearing it.
