How to use

Position the chefs-choice M445 on a stable, level surface and ensure the unit is powered according to the manufacturer instructions.

Usage recommendations

Use the sharpener for regular maintenance rather than heavy re-profiling; check manufacturer guidance for the number of passes and slot selection for different blade conditions. Avoid sharpening serrated knives and be cautious with very thin or specialty blades. For best results, maintain a consistent speed and light pressure while passing the blade through the guided slots.
