On 13 June 1731 Peter Henckels registered the “Zwilling” (German for “Twin”) logo with the Cutlers’ Guild of Solingen. This makes Zwilling one of the oldest trademarks in the world. 40 years later, Peter’s son Johann Abraham Henckels (1771-1850) was born, who would later re-name the company after himself. The Henckels logo has been in the current shape with a red background since 1969.
Henckels produces multiple lines of kitchen cutlery. The Four Star line, introduced in 1976 is a fully forged knife with a molded handle made of polypropylene and a tang which extends into the handle. The TWIN Select series has ergonomic handles which are constructed of 18/10 stainless steel. The TWIN Cuisine features a fully exposed, horizontal tang embedded in a polypropylene handle. Some lines, such as TWIN Professional “S”, have a traditional 3-rivet polypropylene handle. TWIN Four Star II was released in 2006, has a molded handle, and resembles the Four Star except it also has stainless steel end cap featuring the Zwilling logo. Most knives feature blades which are constructed from high carbon, stainless steel which is ice hardened for sharpness and stain resistance. The TWIN Cermax M66 series is constructed using a microcarbide powder steel with clad layers and is manufactured in Japan
