UTC Ultra wire is a non-tarnishing copper based wire used for ribbing, weight, flash, dubbing brush wire and as a body component on nymph and streamer patterns.
It is the essential material needed for tying John BarrÃ¢â‚¬â„¢s famous Copper John nymph.
Flies can be tied completely out of Ultra Wire if you desire. Wrapping two different colors of Ultra Wire together can make a banded, segmented body.
