Mustad 3412CD Hooks - Needle Eye for Wire Leader Rigs
The Mustad 3412CD is an O'Shaughnessy style hook with a needle eye designed for single-strand wire and cable leader connections. The forged short shank adds strength for offshore species. Mustad's Nor-Tempering process and proprietary wire technology produce hooks that are lighter and up to 20% stronger than standard construction. Duratin finish resists corrosion and allows easy sharpening. Four sizes from 7/0 to 10/0 cover standard wire rig applications for trolling and bait fishing. Sold individually.

The Wire Rig Hook
Wire leaders require a needle eye. Standard ringed or brazed eyes are too thick for single-strand wire to pass through cleanly. The Mustad 3412CD has a stamped needle eye that accepts wire and cable without binding or creating weak points in the connection.
The short shank and forged construction provide strength that the 3407DT long shank version does not offer. When you are running wire leaders for wahoo, king mackerel, or bluefish, the 3412CD gives you a direct wire connection with the backbone to handle toothy, hard-fighting species. Sold individually starting at $1.05.

Needle Eye for Wire
The stamped needle eye accepts single-strand wire, cable, and fine-diameter leaders that cannot pass through standard ringed eyes. Wire haywire twists sit cleanly against the needle eye without the bulk that ringed eyes create.
Forged Short Shank
The shorter shank and forged construction provide more strength per unit of weight than the longer-shanked 3407DT. The compact profile gives dead baits more natural action in the water.
Nor-Tempered Duratin
Mustad's Nor-Tempering process produces hooks up to 20% stronger than standard tempering. The duratin finish provides saltwater corrosion resistance and allows touch-up sharpening with a hook hone. Affordable enough for high-volume use.

What is a needle eye? +
A stamped eye with a narrow opening that accepts single-strand wire and cable. Standard ringed eyes are too thick for clean wire connections. The needle eye allows a direct haywire twist connection. Our wire leader guide covers connection methods.
How does this compare to the 3407DT? +
The 3412CD has a needle eye and shorter shank for wire rigs. The 3407DT has a ringed eye and longer shank for standard trolling. Choose the 3412CD when using wire leaders, the 3407DT for mono or fluorocarbon. Our hook guide covers both.
What species is this for? +
Wahoo, king mackerel, bluefish, and any species targeted with wire leaders. The forged construction handles aggressive fighters. Our king mackerel guide covers wire rig hook selection.
What wire diameter fits the needle eye? +
Standard trolling wire from #6 through #12 passes through the needle eye cleanly. Match your wire gauge to target species, not the hook size. Our wire leader guide covers wire gauge selection.
Why forged? +
Forging compresses the steel grain structure, adding strength without increasing wire diameter. The forged 3412CD is stronger than a non-forged hook of the same gauge. Our hook guide covers forging benefits.
Can I use this with mono leaders? +
The needle eye is designed for wire, but mono can pass through it. However, for mono leaders, the 3407DT with its ringed eye provides a cleaner connection. Use the 3412CD when your application specifically requires wire. Our leader FAQ covers leader material selection.
