If you mean “uni” as a fly-tying material, the best matches are the Hareline materials: Hareline Dubbin Hareline Uni Thread 3/0 Waxed Heavy Tying Threads for strong thread wraps, and Hareline Dubbin Uni Flexx, Hareline Dubbin Uni Nylon Stretch, and Hareline Dubbin Uni Yarn for building bodies, ribbing, collars, and segmented profiles on nymphs, streamers, wet flies, and saltwater flies.
If you mean “Uni” as a fishing lure, Thundermist Lure Company Uni-Viper Spoon is the clearest match: it’s a flash-and-flutter spoon that can work in both saltwater and freshwater.
