Gamakatsu B10S Stinger

The Gamakatsu B10S Stinger is a barbed stinger hook available in sizes #2/0-1. It's built around a standard shank, which matches the proportions of most classic dry fly and nymph recipes — if a pattern doesn't specify a shank length, this is what it assumes, paired with heavy wire, one step stronger than standard, adding a little sink rate and useful margin when fishing for larger fish. Tyers reach for it most often when working on general purpose. The sections below break down what each specification actually means at the vice, which patterns suit it, and which hooks from other manufacturers you can substitute when it's out of stock.

Shank length (Std.). This hook has a standard shank, which matches the proportions of most classic dry fly and nymph recipes — if a pattern doesn't specify a shank length, this is what it assumes.

Wire strength (1XH). It's made from heavy wire, one step stronger than standard, adding a little sink rate and useful margin when fishing for larger fish.

Bend and gape (Sproat). The B10S Stinger uses a Sproat bend — a classic rounded profile known for strength and reliable holding.

Eye type (Straight). It's finished with a straight (ring) eye, the most versatile option — it keeps the fly tracking in line with the leader, which suits nymphs and streamers.

Barbed. This is a barbed hook. Many competition rules and an increasing number of catch-and-release fisheries require barbless, so check local regulations — the barb can be pinched down with flat-jawed pliers before you dress the hook.

What size Gamakatsu B10S Stinger should you use?

The B10S Stinger runs from size 0 through 2. This is a larger-size range, better suited to attractor patterns, streamers and bigger quarry than to delicate imitative work. If you're buying this hook for the first time, the mid-range sizes see the most use at the vice, and tracking exactly which sizes you own is where an inventory app earns its keep — it's the detail most tyers forget at the fly shop counter.

What can you substitute for the Gamakatsu B10S Stinger?

If the Gamakatsu B10S Stinger is out of stock, the closest match in the database is the Gamakatsu SL45. When substituting, the specifications that matter most are gape and shank length — these determine whether the finished fly keeps its intended proportions. Wire strength is the next consideration, since it changes how the fly sits in the water: a heavier wire will sink a pattern that was designed to float. Eye type is usually the most forgiving difference, though switching to or from a jig eye changes how the hook rides entirely.
