Tufflock's 100% Fluorocarbon has been designed specifically for demanding lure and jig fishing applications. Manufactured in Japan to rigorous standards to create a fine diameter, abrasion-resistant and supple fluorocarbon leader material. The essential combination of abrasion resistance and knot strength is retained while allowing a fractionally softer leader that allows more action to be imparted to the lure or jig. Designed and tested using decades of on-water experience, Tufflock 100% Fluorocarbon leader performs when it counts!
