Approximately 30 strictly monitored production steps are required before the customer can hold one of these premium quality knives in their hand.

Performance Cut technology is used to produce all the pieces in the Chef’s Edition, Grand Gourmet, Grand Class and Spitzenklasse Plus series. This is in part to thank for the outstanding results achieved by WMF household knives in the latest round of Stiftung Warentest benchmark testing. The Grand Class series chef's knife won the Classic Chef’s Knife category with a score of 1.8. Important characteristics were put to the test, including longevity, sharpness, ergonomics, and ease of cleaning. Stiftung Warentest concluded that: “WMF produces the sharpest steel blades.”
