Russian River · Sizes #2
The Mustad L101AP is a barbed russian river hook available in sizes #2. It's built around a shank one size longer than standard, leaving extra room for a dubbed body or a slightly extended abdomen, paired with the heaviest wire class, for the largest quarry. 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 (1XL). This hook has a shank one size longer than standard, leaving extra room for a dubbed body or a slightly extended abdomen.
Wire strength (5XH). It's made from the heaviest wire class, for the largest quarry.
Bend and gape (Std.). The L101AP uses a standard gape, which keeps the fly's proportions traditional.
Eye type (Down). It's finished with a down eye, the traditional choice, which sets a good hooking angle for dry and wet flies fished on a tippet.
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.
The L101AP runs from size 2 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.
These hooks match closely on the specifications that determine a fly's proportions and behaviour, so they work as substitutes.
If the Mustad L101AP is out of stock, the closest match in the database is the Kamasan B380. 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.
