How to Maintain a Serrated Kitchen Knife Without Ruining Its Teeth

Serrated knives need different sharpening techniques from straight-edged chef’s knives because each scallop has its own shape.

Steps to follow

1. Wash and dry the knife after use.
2. Check whether the maker recommends professional sharpening.
3. If using a sharpening rod, choose an appropriate size for the individual serrations.
4. Work gently on the intended bevel only, following manufacturer guidance.
5. Store the blade with a sheath or protected rack.

Why the approach works

A flat whetstone across the teeth can grind away the profile that makes a serrated knife useful. The correct approach depends on whether the serrations are single-bevel or a more complex design.

Mistake to avoid

Do not force a thick round rod through narrow serrations; that can distort them.

Frequently asked question

Do serrated knives ever need sharpening?

Yes, but often less frequently for light home use, and specialized service can be worthwhile.
