  • Patent number: 7694907
    Abstract: A large arbor anti-reverse fly fishing reel provides by its handle a convenient variable drug control up to a present drag force. The drag knob is preferably designed as a four-vane propeller knob being arranged within a handle depression extending inside the spool. By means of a bayonet coupling, which also serves as a variable drag control device, the handle can be securely attached to the reel thereby locking the spool. The spool can be provided with omega-like perforations for a maximum stability, lightness and ventilation, said ventilation being optionally enhanced by an air turbine formed by said perforation and a portion of the frame and/or a portion of the handle extending inside the spool.
