Store knives safely

Use a block, magnetic strip or blade guards instead of tossing knives in a drawer.

Choose the right knife

A chef's knife handles most jobs, while a paring knife is better for small detail work.

Keep the edge sharp

A sharp knife is safer because it needs less force and slips less often.

Use the pinch grip

Pinch the blade just above the handle with your thumb and index finger for control.

Stabilize the board

Place a damp towel under the cutting board so it does not slide.
