Sampo swivels are protected by law! Our signature design is trademarked by the US government. While there are many imitators, there is only one Sampo Ball Bearing Swivel.
Established in 1948, Sampo changed the face of fishing forever with the introduction of the original ball bearing swivel. These American-made swivels continue to be the industry standard to which all other swivels are compared. There is no substitute for a Sampo swivel!
