The Kamasan B401 Trout Whisker Barb Hooks series features medium wire and standard hook shanks, making it ideal for dries and nymphs. These are classic, tried-and-tested hooks for trying all sorts of flies. They are the same as the B170 hooks, except with a whisker barb (semi-barbless) and are perfect for catch and release. Each pack contains 25 chemically sharpened, needle-point hooks.
