Before You Tie Anything
Lesson: Hooks, Gauge, and the Barb Question
okay. this is the lesson where we actually talk about the hook, which is funny because we've spent four lessons on everything except the hook. that's not an accident. the hook is the thing everything else gets built on, so i wanted you to already understand thread and proportions before we got into it.
let's start with the parts of a hook, because the vocabulary matters and it's not complicated.
the parts you need to know:
- eye — where the tippet goes. up-eye, down-eye, straight eye. for most trout patterns it won't matter much which one you buy, so don't stress over it.
- shank — the straight part, where you'll build most of the fly.
- bend — the curve.
- point — obviously.
- barb — the little backward-facing bump near the point. we'll get to this.
- gap — the distance between the point and the shank. this is the one people underrate.
gauge: thick or thin wire
gauge is just how thick the wire is. a heavy-gauge hook is stronger and sinks faster. a light-gauge hook is more delicate and, on a dry fly, that matters because you want the fly sitting up on the water instead of dragging it down.
so: nymphs and streamers, go heavier gauge. dries, go lighter. it's not a hard rule, it's a "why" thing — heavier wire is more weight, more weight is more sink, and sink is what a nymph needs to do its job.
i'll be honest, i don't think about gauge that hard anymore. i look at what the pattern's supposed to do and pick accordingly. you'll get there too, it just takes tying a few dozen flies before it stops being a lookup and starts being obvious.
gap: the one people skip past
gap is underrated. it's the distance from the point of the hook to the shank, and it determines how much bite the hook actually has when a fish takes it. a wide gap hooks fish better. a narrow gap can look fine on the vise and then let fish shake loose in the water, which is the worst kind of feedback because you don't find out until you've already lost the fish.
for freestone water — the kind you're fishing up the canyon — i lean toward a slightly wider gap than the pattern books always call for. those trout hit fast and they don't get a long look at your fly, so you want the hook doing its job the instant they close their mouth on it. that's the whole game up there: fast water forgives an ugly fly but does not forgive a fly that falls apart or a hook that doesn't set.
the barb question
alright, the barb. some of you have already asked me about this, so let's just do it now.
barbed vs barbless is genuinely a personal call, and i'm not going to pretend there's one right answer, but here's the actual difference: a barb holds a fish on better once it's hooked. it also does more damage getting the hook out, and it's slower to remove, which matters if you're catch-and-release, which most people fishing local water are.
a lot of tiers just pinch the barb down with pliers after buying barbed hooks — you get a barb when you need it (some big expensive trip where you really don't want to lose a fish) and you can flatten it the rest of the time. that's what i do. i buy barbed hooks, and about half of what i tie i pinch flat before i even start.
quick caution here, not a big deal but worth saying plainly: hook points are sharp enough to catch skin easily, and if you're pinching barbs with pliers, keep your other hand well clear of the point. it's a two-second job and it's easy to get a little careless on your tenth hook of the night.
a practical way to start
don't buy fifteen different hook types. buy one standard dry fly hook and one standard nymph hook, both in a couple of sizes — say a 14 and a 16 to start, since those cover a lot of what you'll fish locally. get comfortable with those before you start chasing every specialty hook the catalog offers.
and this is where i'll say the thing i always say: proportions matter more than the hook you chose. a well-proportioned fly on an okay hook beats a poorly-proportioned fly on the exact "correct" hook every time. don't let hook selection become a stalling tactic before you actually sit down and tie.
which brings me to my first dozen flies, which i think about every time i teach this lesson, honestly. i didn't overthink the hooks. i overthought the thread. i was so worried about things coming loose that i just kept wrapping thread over every head, more and more, convinced more wraps meant more secure. they didn't. they meant lumpy, bulky heads that looked like something a cat would swat around a kitchen floor. actually — that's literally what happened. brittney found one in the junk drawer two years later and asked me straight up if it was a cat toy. it was a hare's ear. allegedly.
the lesson isn't really about thread, it's about confidence. i didn't trust that a hook properly gapped and a fly properly proportioned would hold. so i kept adding stuff that didn't need to be there. get your hook selection sorted, trust your proportions, and stop compensating with extra material you don't need.
before next time: grab a handful of hooks in a couple sizes — doesn't matter much where from, a shop or an online order both work fine — and just look at the gap on each one. hold them up next to each other. you'll start seeing the differences we talked about today, and that's really the whole point of this exercise.
