Bobbins, scissors (one good pair for materials and another for cutting wire if you're using brushes. Could also just be a pair of wire cutters) a bodkin, a comb/brush, and of course a vise. That's pretty much a complete list of tools needed, imo. Learn to whip finish by hand. I bought the tool and now it sits in a drawer. Waste of money. So was the dubbing loop twister. Maybe if I did a ton more flies with dubbing loops, but you can also just use a paper clip. Best advice I've seen to beginning tiers (that I of course ignored completely ☺) is to find a fly that works and buy what's needed to tie that fly. At most, get stuff to do a light and dark version. It's tempting to buy a bunch of stuff and get creative but if you can stick to a few patterns you'll develop tying skills and not end up needing a storage unit to keep all the stuff you don't even use.
