Permanent sharpness^**

The secret lies in the exclusive WMF Diamond Cut technology. For this purpose, the blade is first subjected to an innovative hardening process before the optimal acute cutting angle is ground mechanically and with laser-assisted precision. Finally, the entire blade is given an extremely hard, diamond-like coating using a PVD process under vacuum. This protects the cutting edge from wear and thus ensures constant sharpness.^**

The Ultimate Black knife series combines holistic, timeless design of pure elegance with maximum performance, hand-flattering balance, and constant sharpness. Knives to fall in love with.
