Mustad 7691DT Big Game Hook - Duratin Finish
The Mustad 7691DT is the duratin version of Mustad's classic big game hook. The thick shank and recurve bend handle tuna, marlin, and other offshore species. The knife edge point penetrates deeply on the hookset. The brazed ring eye adds strength at the connection point. Duratin finish provides corrosion resistance and allows easy sharpening with a hook hone. Six sizes from 7/0 to 12/0 cover standard big game applications. Sold individually from $2.89, making the 7691DT the affordable alternative to the stainless 7691S.

Big Game Performance at a Duratin Price
The 7691DT delivers the same thick shank, recurve bend, and knife edge point as the stainless 7691S at roughly half the cost. The duratin finish is the trade-off. It provides adequate saltwater corrosion resistance but will eventually corrode with heavy use. For anglers who go through hooks regularly or sharpen before every trip, duratin is the practical choice.
The brazed ring eye is a strength upgrade over stamped eyes. It holds under heavy drag loads without spreading. Combined with the thick shank, the 7691DT handles the sustained pressure of big game fights. Stock these for high-volume trolling where you need reliable big game hooks without premium pricing.

Thick Shank Recurve Design
Same proven thick shank and recurve bend geometry as the stainless 7691S. The thick wire handles heavy drag settings and sustained runs. The recurve keeps the point buried as the fish changes direction during the fight.
Brazed Ring Eye
The brazed ring eye provides a reinforced connection point that resists spreading under load. Accepts crimps, knots, and wire connections. The brazed construction adds strength over standard stamped or turned eyes.
Duratin Finish
Duratin provides saltwater corrosion resistance at a lower cost than stainless steel. The softer surface allows easy touch-up sharpening with a diamond hook hone. Affordable enough for high-volume trolling where hooks are replaced regularly.

7691DT vs 7691S? +
Same hook shape and size range. The 7691S is stainless steel (no corrosion, higher cost). The 7691DT is duratin (some corrosion potential, lower cost, easier sharpening). Choose stainless for hooks you reuse, duratin for high-volume trolling. Our hook guide covers finish comparisons.
What does DT mean? +
DT stands for Duratin, Mustad's proprietary corrosion-resistant finish. Duratin hooks are more affordable than stainless and easier to sharpen. They provide adequate saltwater protection for standard use. Our hook guide covers Mustad finishes.
What size for tuna? +
9/0 and 10/0 for yellowfin tuna. 11/0 and 12/0 for giant bluefin. 7/0 and 8/0 for smaller tuna and mixed offshore species. Our yellowfin guide and bluefin guide cover hook sizing.
How does the recurve work? +
The recurve angles the point slightly back toward the shank, keeping the hook buried in tissue when the fish changes direction. Standard straight bends can pull free during head shakes and direction changes. Our hook guide covers bend types.
What is a brazed ring eye? +
The ring is brazed (soldered) closed rather than simply bent. This prevents the eye from spreading open under heavy drag loads. Brazed eyes are stronger than standard turned or stamped eyes. Our hook guide covers eye construction.
Can I sharpen duratin hooks? +
Yes. Duratin is softer than stainless and sharpens easily with a diamond hook hone. Touch up the knife edge point before every trip. Regular sharpening is the key advantage of duratin over stainless finishes. Our hook guide covers hook maintenance.
