Why Can a Dull Kitchen Knife Be More Dangerous?

A dull knife may require extra force and is more likely to slip unpredictably on a firm or smooth food surface. A sharp knife still poses a cutting hazard, but it usually gives the cook better control.

Watch for slipping

A knife that skates across a tomato skin or onion instead of starting a clean cut may be too dull or poorly suited to the task. Forcing the blade toward your hand can cause injury when it finally catches.

Build safer habits

Use a stable cutting board, keep the food from rolling and curl guiding fingertips away from the cutting line. Work at a deliberate pace rather than rushing to compensate for dullness.

Maintain and store the edge

Hone or sharpen according to the knife type, wash and dry promptly, and use a sheath or protected rack for storage. Do not attempt unsafe tests by running a finger or thumb along the edge.

Frequently asked questions

Is a sharp knife automatically safe?
