Ginsu is a brand of direct marketed knives. The brand is owned by the Douglas Quikut Division of Scott Fetzer, a Berkshire Hathaway Company. The brand was heavily promoted in the late 1970s and 1980s on U.S. television by using infomercials characterized by hawker and hard sell pitch techniques. The commercials generated sales of between two and three million Ginsu sets between 1978 and 1984.
