How many things can you think of that look exactly the same as they did back in 1976 when they are fresh from production? Whether cars, electrical appliances or jeans: almost everything has a different design than it used to have. Almost. The FOUR STAR knife series from ZWILLING is an exception. And for good reason: Each individual knife is an example of how steel and plastic can be optimally combined to create a high-quality cutting tool. And we haven't changed a thing to this day because there's nothing to improve.
