Sampo, Inc. was established in 1948 in Daly City, California. An avid angler looked to devise a way of preventing line twist. His introduction of ball bearing swivels would change the face of fresh and salt water fishing forever. In 1957 Sampo, Inc. was sold. The company moved to its present Barnevold, New York location. As the market for their swivels continued to increase Sampo invested heavily in state-of-the-art tooling and machinery that not only kept orders filled but also allowed for expansion of the product lineup. Today Sampo continues to reign as the world's number one manufacturer of premium quality swivels.
