Wüsthof’s Precision Edge Technology
Wüsthof’s Precision Edge Technology, PEtec, has set the new standard for superior blade sharpness. Through a process that uses computer-controlled robotics, Wüsthof’s PEtec yields a supremely smooth and refined edge that dramatically increases sharpness and, importantly, sharpness retention along the entire length of the blade. The result is a knife that stands the test of time for both home cooks and professional chefs.
Before sharpening, the blades are measured using lasers to ensure accuracy
Computers calculate the precise sharpening angle for each blade
Precision robots then sharpen the blades on a whetstone
The knives are given a final polish using a specialised disc
On the left, you can see the results using PEtec technology and, on the right, the results using standard sharpening technology. The cutting edge produced by a knife using the PEtec process is extremely thin. This is what produces the exceptional sharpness.
All Wüsthof knives produced using PEtec technology are also independently tested by a scientific research institution in Germany, the FGW (Forschungsgemeinschaft Werkzeuge und Werkstoffe).
The quality of forged Wüsthof knives produced using the PEtec process is significantly higher than those produced by a standard manual sharpening process.
PEtec technology gives all Wüsthof knives an extremely high cutting performance with a 20% sharper edge than conventionally sharpened knives.
Impressively, the technology doubles the edge retention and gives Wüsthof knives an optimum cutting edge along the entire length of the blade.
While Wüsthof’s knives are sharp from the start, it is really important to learn how to care for and maintain your knives to ensure you get the most out of your blades for many years to come. Here is a quick knife care guide, which will help ensure your Wüsthof knives are always in the best possible condition.
