Wusthof Part 4: Precision Edge Technology

Since you know about the steel and how the forged knives are made. I thought we’d share a little bit about Wusthof’s Precision Edge Technology. (Or why Wusthof knives are better than others).

The latest cutting performance tests carried out by the FGW (Forschungsgemeinschaft Werkzeuge und Werkstoffe e.V., a German research association for tools and materials based in Remscheid) confirm that WUSTHOF forged knives offer the best quality when compared to other well-known, single-layer brands.

Here’s why:

The extensive tests were carried out in accordance with DIN EN ISO 8442-5. WUSTHOF knives have a considerably higher ICP (Initial Cutting Performance) and maintain this performance for an extremely long time (TCC = Total Card Cut).

When compared with the winners in the “cook´s knife” category awarded by German consumer organization “Stiftung Warentest” in its 1st edition of 2008, forged WUSTHOF knives featuring the new PEtec technology produce a result which is about 20% higher.

The Technology:

  • -The blades are measured by laser before sharpening.
  • -Computer programs calculate the precise sharpening angle for each blade.
  • -The knives are then sharpened on a whetstone using precision robots.
  • -Finally, the knives are given a final polish using a special disc.

The Benefits:

  • -Extremely high initial cutting performance.
  • -Exceptionally long edge retention / long service life of blade.
  • -Optimum cutting edge along the entire length of the blade.
  • -Unique, consistently high and reproducible quality.

PEtec from WUSTHOF – superior sharpness for professional and home cooks!
