Crimping provides a solution for making advanced rigs! We pass a line through a small double-tube metal crimp, forming a loop, and then simply clamp it with the pliers. In this way, we can create heavy-duty end loops without knots, even on stiff, thick casting leads or fluorocarbon lines! The crimping pliers are primarily recommended for our SBS crimps, which are available in two sizes (0.6 and 0.7 mm). (Also available in a kit!)
