What it is
The Hareline Stonfo Comb Brush is a compact fly tying comb and brush with a fine-toothed plastic comb and stiff nylon bristles. It’s lightweight and durable in the hand, and it’s built for controlling and cleaning fibres rather than moving bulk material.
What to tie with it
Use the comb side to untangle and straighten fibres on the hook, and to pull out and align materials like fur and synthetics before you bind them down. Use the stiff bristles to tease dubbing so it stands up spiky and buggy, and to clean up and shape deer hair after stacking or trimming.
Flies and the fish they're for
This tool is part of tying and maintaining dubbing-heavy nymphs and emergers where you want a rougher, more alive profile; those are trout flies in rivers and stillwaters. It’s also handy on deer-hair patterns after they’ve been fished or after you’ve trimmed them, which covers everything from bass bugs for largemouth and smallmouth to buoyant deer-hair trout dries on moving water. On the water, it doubles as fly maintenance for brushing out dirt and debris so your bugs keep their profile and movement for the next fish.
