of this hook is not completely enclosed rather it has an opening 20 created by the incomplete looping of the structure that constitutes the eye this opening 20 needs to be large enough to allow the free passage of the fishing line 22 in and out of the eye a larger opening would decrease the structural strength of the eye and it is therefore not recommended moreover while the eye of a generic hook may or may not be circular the eye 18 of this invention as specified in this embodiment is required to be round the knob like device 30 is a separate component of the invention that functions in cooperation with the line 22 and the hook 39 s eye 18 referring to both fig1 and 3 this device is perforated along its longitudinal axis to provide a hole 32 through which the fishing line 22 can be threaded and secured by a stopper knot 24 the diameter of the opening 32 is uniform along the main portion of the body of the device 30 and is sufficiently large to permit the free insertion of the line 22 but small enough to cause the knot 24 to catch and be retained as the line slides out of the device as illustrated in fig3 said device 30 consists of three functionally distinct parts shown along the device 39 s main axis they are a knob 34 a neck 36.
