Abstract
A fishing lure comprises a spinning blade that rhythmically changes its direction of rotation. One or more unique link members limit the cyclical amount of blade rotation in either direction. As the wound up link members pause the rotation of the blade, a hydrodynamic force still trying to turn the blade causes the lure body to undergo a slight twist motion. The wound up link members then begin to unravel from a remaining hydrodynamic force still incident on the moving lure. This is sufficient to start the blade spinning in the opposite direction until it is again rotatably limited by the link members and again imparts a twitch motion on the lure body. This cycle continues to repeat indefinitely as the lure moves at a generally constant speed. The cyclically rhythmic alternating blade rotations and the corresponding body twitch motions create lure behavior that better mimics real life prey.
