DOHIKU HDO hooks. These barbless hooks have been specially designed and developed for "blood worm flies" according to the requirements of centuries of tested fly shapes by over fly fishermen from behind the Lamanche Canal/ English channel/, where was born the wet fly fishing. Our consultant was Mr. Bill Eadie. HUGE THANK! The shape of the hooks shows the bending and movement of aquatic animals and the special for the twisting of worms. These hooks are improved form for free-floating flies. The shape of these hooks is unique in its balanced shape and also allows the imitation of flies as well as leeches, crustaceans, and larvae of flies as well as hydropsyche larvae, of course, as well as terrestrial insects.
