FAQ

Knives — FAQ

How often should I sharpen my knives?

For regular home cooking, sharpening once every few months is usually sufficient. However, if you notice the blade tearing instead of slicing, it is time for a touch-up.

Are electric sharpeners safe for high-end steel?

Most modern electric sharpeners are safe for standard stainless steel. Always check the manufacturer's guidelines if you own specialized Japanese or high-carbon blades.

What does the sharpening stage mean?

The first stage typically grinds a new edge, while the second or third stages hone and polish the metal. Using all stages ensures a smoother, longer-lasting cut.

Can I sharpen scissors with these?

Only if the product explicitly states it has a dedicated scissor slot. Never force scissors into a slot designed for kitchen knives.

Why is diamond abrasive preferred?

Diamond is one of the hardest materials available, allowing it to sharpen even the toughest stainless steel quickly. It remains effective longer than ceramic or stone wheels.

Do I need to clean the sharpener often?

Yes, metal filings can build up inside the slots. Regular cleaning prevents debris from damaging the sharpening wheels or your knives.
