How to Sharpen a Chef Knife with a Self-Sharpening Block

Quick answer

To sharpen a chef knife with a self-sharpening block, simply insert the blade into the integrated sharpening slot and pull it through a few times. No manual honing or separate sharpener is needed.

Steps to sharpen your chef knife with a self-sharpening block

1. 1. Prepare the block: Place the self-sharpening block on a stable, dry countertop. Ensure the sharpening slot is clean and free of debris. A dirty slot can scratch the blade or reduce sharpening effectiveness.
2. 2. Insert the blade: Hold the chef knife by the handle with the blade pointing down. Align the blade with the sharpening slot and insert it fully, keeping the blade straight. Do not twist or angle the blade; the integrated sharpener works best with a straight, even pull.
3. 3. Pull through gently: Pull the knife straight back out of the slot in one smooth motion. Repeat 3–5 times for a standard sharpen, or 8–10 times if the blade feels noticeably dull. Pulling too fast or with excessive force can cause uneven sharpening or damage the edge.
4. 4. Wipe the blade: After sharpening, wipe the blade with a clean cloth to remove any metal dust or debris left by the sharpener. Metal particles can transfer to food if not wiped away.
5. 5. Store the knife properly: Return the knife to its designated slot in the block. The self-sharpening mechanism will hone the edge again during storage. Storing the knife loose in a drawer can dull the edge and bypass the sharpening benefit.
