American Fishing Wire Mighty-Mini Crane Swivels are 100% stainless steel and are 3 times stronger than conventional brass swivels of the same size. Smart anglers know that terminal tackle can spook wary game fish. That's why AFW engineered this line of compact, 100% stainless steel crane swivels to be smaller and stronger than the leading brands of swivels on the market. Mighty-Mini Swivels also have less drag and provide enhanced rotation for more strikes.
