Best Automatic Sharpening Technology Over Time

Discover the evidence behind the effectiveness of Tefal EverSharp technology. Enjoy exceptionally sharp knives that will stay with you longer.

Can knives stay sharp even through years of daily use?

Yes! That is exactly what EverSharp technology was designed for. We have confirmed its effectiveness in laboratory tests that simulated up to 10 years of use.

Why Does It Matter?

Dull knives mean more effort, less precision, and simply a worse kitchen experience. EverSharp eliminates this problem.

Thanks to the integrated sharpening system, your knives:

• Stay sharp every day
• Do not require manual sharpening
• Are always ready to work

No extra accessories. No hassle. And no frustration.

How does EverSharp work in practice?

The sharpening system is integrated directly into the knife block. Every time you take the knife out or place it back into the block, it is automatically sharpened.

The Spring Mechanism:

• Provides constant, optimal pressure
• Works independently of the user's strength
• Guarantees repeatable results

As a result, the knives maintain optimal sharpness without any need for manual sharpening.

Effectiveness Proven in Tests

Below, we present the results of tests conducted in an independent laboratory, simulating 10 years of knife use with daily sharpening.

The CATRA test (ISO 8442-5) measures the durability of blade sharpness – the higher the CER (Cutting Edge Retention) score, the longer the knife stays sharp.

Test conducted in an external laboratory on knife sets with a block equipped with an integrated spring sharpening system. Simulation of 10 years of use (1 use per day, 10 cuts on a plastic cutting board, sharpening according to the manufacturer's recommendations). CATRA test compliant with ISO 8442-5 standard.

How to Read These Results?

• The minimum required level for CER is 150.
• The higher the score, the better the sharpness retention.
• Tefal's results significantly exceed the required standards.
• Competitors' products achieve lower values.

Conclusion: Tefal EverSharp knives maintain higher sharpness even after a long period of use.
