Wire traces
Tackle · Last reviewed 2026-08-10
A short length of wire between line and hooks, and the single most important piece of terminal tackle in predator fishing — for the fish's sake, not the angler's.
Safety
Fish welfare — Can cause serious injury or death
Fishing for a toothy predator without a bite-resistant trace produces bite-offs. The fish swims away with hooks — often a treble-armed lure or deadbait — embedded in its mouth, which impairs feeding and frequently kills it slowly.
What reduces it: Use a wire or heavy fluorocarbon trace on every session where a toothy species might take, replace traces that show kinks or damage, and use barbless or crushed-barb hooks so that a fish that does get away has the best chance of shedding them.
A pike's teeth will part monofilament and braid quickly and reliably. A wire trace is the answer, and this record states plainly why it is not optional: a fish that bites through the line swims away with hooks in its mouth, frequently attached to a lure, and it is not a lost fish for the angler so much as a damaged one for the water.
That framing matters because a great many anglers treat the trace as insurance against losing tackle. It is not. It is the piece of equipment that prevents a foreseeable, avoidable harm to the fish, and it should be regarded in the same category as an unhooking mat rather than in the same category as a landing net.
Wire types differ in useful ways. Multi-strand wire is supple and lets a bait behave naturally; single-strand is stiffer, thinner and kinks permanently once bent; titanium is expensive, kink-resistant and springs back. Heavy fluorocarbon is used as a compromise for species with less severe dentition, and it is a compromise rather than a substitute.

What it does
Places a bite-resistant material between the main line and the hooks, so that a fish with cutting dentition cannot part the connection. It also provides abrasion resistance against gill rakers and against structure during a fight.
How to choose one
- Use one for every session targeting a species with teeth, without exception — including when lure fishing for perch in water that also holds pike.
- Match suppleness to presentation: multi-strand for natural bait movement, single-strand or titanium where a stiff, direct connection is wanted.
- Length should exceed the length of the quarry's jaw with margin — a trace that ends inside the mouth has failed.
- Check for kinks and rust after every fish; a kinked single-strand trace is a broken trace waiting to happen.
- Crimped and knotted connections both work; whichever is used must be inspected rather than assumed.
What the numbers mean
BREAKING STRAIN in pounds, typically 20–40 lb for pike work — considerably above what the fish can pull, because the requirement is bite resistance rather than tensile strength. STRAND COUNT: 1×7, 7×7 and 49-strand describe construction, with more strands giving more suppleness at the same strength. MATERIAL: stainless steel is standard and cheap; titanium costs several times more, does not kink, and springs back into shape. COATED wires have a plastic sheath that improves handling and hides the wire, at the cost of the coating eventually splitting.
Care, and how it fails
Wire fails at kinks, at crimps, and at the point where it enters a swivel. Single-strand wire that has been bent sharply is permanently weakened and should be replaced rather than straightened. Rinse after use — particularly in salt — and inspect the whole length after every fish, especially the last few centimetres at the hook end where the abrasion is. A trace is a consumable, and treating it as a permanent item is how a fish ends up with a lure in its jaw.
What this is called elsewhere
FishingHQ’s headword is the term used in Britain & Ireland.
- Wire leader — North America, Australia, New Zealand, Global
- The same component under the international word for the section it belongs to. 'Trace' is British; 'leader' is everywhere else.
- Bite trace / shock trace — Britain & Ireland
- British sea-fishing usage distinguishing the short abrasion-resistant section at the hook from the longer shock leader used for casting. Two different jobs sharing the word trace.
Where to go next
Fish it is used for
African tigerfishLarge fang-like teeth that overlap the jaws when the mouth is closed. A wire trace is required tackle rather than a refinement, and this is a fact about the fish rather than a preference.- BluefishTriangular razor-edged teeth that cut monofilament, hooked fish and fingers. A wire trace is required tackle, and this is a fact about the fish.
Golden doradoConical teeth in a powerful jaw shear through mono. A heavy trace is required tackle rather than a refinement, and this is a fact about the fish.
Northern pikeThis is a requirement rather than a preference: a pike will part monofilament or braid, and a fish that bites through swims away with the hooks still in it.

What it works with
- Haywire twistThe termination single-strand wire requires. The distinction matters and the trace's packaging is the authority on it: multi-strand and nylon-coated wires behave differently, many are crimped, and some of the coated ones genuinely can be knotted.
- Wire trace deadbait rigTwo trebles on a wire trace, positioned in the outer flesh of a deadbait so the fish can be struck promptly and hooked in the jaw.

Understanding it
- Leaders and tracesWire answers a cutting problem rather than a strength problem, and that distinction is why heavier nylon is not a substitute.
- What a leader is, and when you need oneThe bite-off job is the one where the leader material is not a preference: a fish that swims away trailing a severed trace has been condemned rather than lost.
