What it is The Hareline Stonfo Dubbing Brush Device is a bench tool for building your own dubbing brushes. It’s made to hold wire while you layer in fibers and other materials, then twist everything into a tight, consistent brush you can wrap on a hook. What to tie with it Use it to make custom brushes by combining fibers with wire and even mixing in tinsel for flash and bulk. Once the brush is made, you wrap it like a chenille body or a hackle rope to build buggy bodies, collars, and streamer shoulders fast and evenly, whether you’re tying sparse dries or big, packed streamers. Flies and the fish they're for Brush-built bodies and collars show up everywhere from trout nymphs to warmwater and saltwater streamers, because you can match the density and mix of materials to the job. A dubbing brush like this is a common way to build shaggy, buggy profiles for trout and grayling in rivers, and it also shines for larger baitfish-style flies where you want a lot of movement for fish like smallmouth, stripers, and redfish. Even though specific patterns aren’t listed here, the whole point is you can recreate the “brush” components found in many modern trout flies and big-fish streamers with your own blend.
