Knives — FAQ

Are electric sharpeners safe for expensive knives?

Most modern sharpeners are safe if you use the correct stage. Always follow the manufacturer's angle guide to prevent unnecessary metal removal.

How often should I sharpen my knives?

For daily home use, a quick hone once a month is sufficient. If you notice the knife struggling with produce, it is time for a full sharpening.

Can I sharpen serrated knives electrically?

Yes, but only if the sharpener specifically supports serrated edges. Check your product manual to ensure the grinding head is compatible.

What does the 'stage' mean in sharpeners?

Stages represent different grit levels. The first stage usually repairs the edge, while the final stage polishes it to a razor-like finish.

Do I need to add oil or water?

Most electric sharpeners are designed to be used dry. Adding liquids can damage the internal motor and abrasive wheels.

Is the best knife sharpener electric worth the cost?

Absolutely, as it extends the life of your expensive cutlery significantly. It saves you money on professional sharpening services and ensures safer cooking.
