Learn how to properly use a self-sharpening knife block like the Tefal EverSharp Daily set. Simple steps to keep your kitchen knives razor-sharp with minimal effort.
Quick answer
A self-sharpening knife block hones your blades every time you slide a knife in or out. To use it correctly, simply store your knives in the designated slots and let the built-in sharpening mechanism do the work — no extra tools or skill required.
Why a self-sharpening block saves you time
Traditional knife sharpening requires a whetstone, electric sharpener, or professional service. A self-sharpening block automates the process: each time you remove or replace a knife, the blade passes through ceramic or tungsten rods that realign the edge. This keeps your knives consistently sharp without extra effort.
The Tefal EverSharp Daily set includes an integrated sharpener built into the block. It works with the stainless steel blades to maintain a keen edge for everyday slicing, dicing, and chopping.
What the integrated sharpener does and doesn't do
The integrated sharpener in a self-sharpening block is designed for regular maintenance — it hones the edge and removes minor dullness. It is not meant to repair heavily damaged blades, reshape a chipped edge, or change the blade angle. For major repairs, a professional sharpener or replacement is needed.
Because the mechanism is fixed inside the block, you cannot adjust the sharpening angle. This is fine for most home cooks, but enthusiasts who prefer a specific bevel may want a separate sharpening system.
How to use your self-sharpening knife block in 5 steps
- Insert each knife into its correct slot: Match the blade size to the labelled slot. Push the knife all the way in until the blade contacts the sharpening mechanism. You will feel slight resistance — that is normal. Forcing a knife into the wrong slot can damage the edge or the sharpener. Always check the slot size.
- Pull the knife out firmly and smoothly: Grasp the handle and withdraw the knife in one steady motion. The sharpening rods will hone the edge as the blade slides past them. Do not wiggle or twist the knife during removal. A slow or hesitant pull may not engage the sharpener evenly. Use a confident, straight motion.
- Use the knife for your task: The blade is now ready for cutting. You will notice a sharper edge compared to a knife stored in a plain block. For best results, use the correct knife for each job — a chef's knife for chopping, a utility knife for slicing, etc. A self-sharpening block maintains the edge but does not replace proper cutting technique. Avoid cutting on glass or stone boards.
- Return the knife to its slot after use: Wash and dry the knife first (hand wash recommended). Slide it back into the same slot, blade-first, until it clicks or stops. The sharpener will hone the edge again during insertion. Never store a wet knife in the block — moisture can dull the blade and damage the sharpening rods.
- Clean the block periodically: Wipe the exterior with a damp cloth. Do not submerge the block in water. Every few months, use a soft brush to remove crumbs or debris from the slots. Check that the sharpening rods are free of metal filings. Built-up debris can reduce sharpening effectiveness. A quick clean keeps the mechanism working properly.
