The Swiss CDC Multibrush is simply the nicest dubbing brush made. The brush end with the bristles is intuitive to use, and can be used in precise places by holding it like a pencil. The serrated end is used like a comb to brush out underfur, or to pick out large composite loops on streamers and steelhead flies. The V-shaped end can be used as a bodkin, and can be used to 'double' or fold back hackle fibers on steelhead flies and other hackled streamers. Also, the front brush is replaceable!
If you want the best and most precise dubbing brush made, the Swiss CDC Multibrush is it.
