Hareline Lead Wire is a classic fly tying material used to add weight and improve sink rate on nymphs, streamers, wet flies, and other subsurface patterns. Soft, malleable, and easy to wrap, this lead wire molds cleanly around the hook shank to help flies get down quickly in deeper water, faster currents, and technical fishing situations.
Available in multiple diameters, Hareline Lead Wire gives fly tyers control over how much weight they add to a pattern. Smaller sizes are ideal for delicate nymphs and slim-bodied trout flies, while larger diameters provide heavier weighting for stoneflies, streamers, leeches, and deep-sinking patterns. It can also be used to shape tapered or widened underbodies before covering with thread, dubbing, chenille, or other fly tying materials.
Hareline Lead Wire is one of the most dependable ways to add internal weight to a fly without changing the outside appearance too much. It wraps easily, stays in place once secured, and lets tyers fine-tune balance, sink rate, and body shape. Whether you are tying a weighted Hare’s Ear, stonefly nymph, Woolly Bugger, streamer, or custom subsurface pattern, this wire gives you simple and effective control over how your fly fishes.
Hareline Lead Wire is ideal for tying weighted nymphs, stonefly nymphs, streamers, Woolly Buggers, leech patterns, wet flies, jig-style flies, Euro nymphs, Czech nymphs, and other subsurface patterns that need added weight or a shaped underbody.
When using Hareline Lead Wire with bead head flies, leave a small gap between the bead and the wire wraps so you have room to tie off materials and finish a clean head. Hold the wire firmly against the hook shank while wrapping, then secure it with tight thread wraps. You can slide the wire forward or backward before locking it down to adjust the fly’s balance and underwater action.
Soft Malleable Lead Wire - Wraps easily around hook shanks and can be shaped, adjusted, or positioned before being secured with thread.
Adds Sink Rate to Flies - Helps nymphs, streamers, and wet flies sink faster and stay deeper in the water column.
Great for Body Shaping - Useful for building tapered bodies, wider underbodies, and balanced fly profiles before applying dubbing or body materials.
Multiple Diameter Options - Available in several sizes so tyers can match wire thickness to hook size, fly pattern, and desired sink rate.
Easy to Secure at the Vise - Once wrapped and locked down with thread, the wire provides a stable weighted foundation for durable subsurface flies.
