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, which celebrated its 40th anniversary in 2016, 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. No wonder that the series is a global bestseller: Over 32 million FOUR STAR knives have been sold to date. And we haven't changed a thing to this day because there's nothing to improve.
