Wire Fishing Line And Leaders

Aquateko's Knot 2 Kinky Nickel Leader Wire is made with a special superelastic alloy, allowing it to be bent at least ten times more without permanent deformation. Its unique formula of Nickel and Titanium creates a high degree of elasticity and strength that can endure even the toughest battles with fish.

It is further programmed to stay straight with a complex annealing process for reliability. With higher tensile strength than ordinary steel leaders, Knot 2 Kinky is the ideal choice for both inshore and offshore fishing, eliminating the frustration of constantly changing kinked rigs.

Knot2Kinky wire leader is knottable, you don't need crimps or tools for this leader.  It is extremely elastic yet has a very high abrasion resistance.  It's made of nickel titanium so it has stretch, won't rust, ties with easy knots, and replaces normal steel wire.

AFW Surfstrand Stainless Steel 1x7 Wire Leader is made of corrosion resistant, spring temper stainless steel. Compared to our competitor’s old style 1x3 construction, Surfstrand’s 1x7 construction offers higher break strength and more realistic action.

The wire is specially stranded to deliver superior kink resistance, and the high strength of stainless makes this an excellent wire for leaders, lures, and trolling. Camouflaged

Brown finish minimizes reflections and disappears beneath the water. Attach Surfstrand using crimping sleeves and crimping pliers or tie with a Figure 8 Knot. Made in USA by AFW.

Made from 304 stainless steel for maximum durability and bite resistance, AFW Tooth Proof Stainless Steel Wire Leader is a single-strand leader from American Fishing Wire offered in 30-foot lengths with bright and camo finishes. Utilize this product as a bite guard for sharks and other toothy predators.

For best results, use a dedicated wire cutting tool like that found on the AFW Crimping Pliers; available here. Connect hooks and lures with haywire twists, and use albright knots to attach the wire to the leader.

The Lead Masters Shark Rig is a pre-built shark fishing rig constructed with stainless steel stranded wire and a Mustad tin hook — the two components that matter most for shark fishing where a standard monofilament or fluorocarbon leader would be severed immediately on contact with a shark’s teeth or rough skin. The stainless steel stranded wire provides bite resistance and abrasion resistance that no leader material other than wire can match in direct shark contact. Available in three configurations: 6/0 and 8/0 hooks on 135 lb wire for smaller shark species and inshore shark fishing, and a 9/0 hook on 250 lb wire for larger shark species and offshore applications where heavier wire is required.

Key Features

• Stainless Steel Stranded Wire — Bite & Abrasion Resistance — The stainless steel stranded wire leader is the critical component of any shark rig; shark teeth and rough skin (dermal denticles) will cut through monofilament, fluorocarbon, and even heavy braid on contact; stainless steel stranded wire is the only leader material that provides reliable bite resistance for direct shark contact; stranded construction provides flexibility for natural bait presentation while maintaining the wire’s structural integrity.
• Mustad Tin Hook — Premium Hook Quality — Mustad is one of the most trusted hook manufacturers in saltwater fishing; the tin finish provides corrosion resistance in saltwater environments; hook size scales with wire strength — 6/0 and 8/0 for the 135 lb wire configurations, 9/0 for the 250 lb wire configuration — ensuring the hook gap and wire strength are properly matched for the target shark size.
• Wire Strength Matched to Hook Size — The 6/0 and 8/0 hooks are paired with 135 lb wire for smaller shark species and inshore applications; the 9/0 hook is paired with 250 lb wire for larger shark species and offshore applications where heavier wire is needed to handle the additional stress of larger fish; choosing the correct wire strength for the target species reduces the risk of wire failure on the hookset and during the fight.
• Three Hook Size Options — 6/0, 8/0, 9/0 — Hook size selection depends on the target shark species and bait size; 6/0 for smaller inshore sharks (Leopard Shark, Smoothhound) with smaller baits, 8/0 for mid-size sharks (Thresher, Mako) with medium baits, 9/0 for larger shark species (Hammerhead, Bull Shark, Tiger Shark) with large whole baits.

Variant Selection Guide

Best For

• Inshore Shark Fishing — The 6/0 and 8/0 / 135 lb wire configurations for inshore shark fishing from the beach, pier, or boat; effective for Leopard Shark, Smoothhound, and smaller inshore shark species that are common targets in California and Pacific coast inshore waters.
• Offshore Shark Fishing — The 9/0 / 250 lb wire configuration for offshore shark fishing targeting larger species; the heavier wire and larger hook are required for Hammerhead, Bull Shark, Tiger Shark, and other large offshore shark species where 135 lb wire would be insufficient.
• Any Application Requiring Wire Leader — The stainless steel stranded wire construction makes this rig effective for any species with teeth or rough skin that would cut through standard leader material; also effective for Barracuda, large Yellowtail, and other toothy saltwater species where a wire leader is preferred.

SPRO's Slow Pitch Assist Mono features a monofilament core that offers superior stiffness and abrasion resistance compared to fluoro, as well as two colors and sizes to suit your preferences.
