The TUFFLOCK 100% Fluorocarbon is designed specifically for demanding lure and jig fishing applications and manufactured in Japan to exacting standards to create a thin diameter abrasion-resistant and supple fluorocarbon leader material. The vital 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.
