Abstract: A fishing lure oscillator, comprising a bent, oblonged, essentially elliptical foil having relatively uniform thickness. Near one end of the foil, a connection is made to an appendage, and near the opposite end of the foil a connection is made to another appendage. Both appendages, serving as a framing device to support the foil, originate from a common base which is adapted to be joined with a fishing lure. When joined with a lure and pulled through a body of water, an outwardly contoured portion of the foil is disposed directly against the flow of water whereby the force of water against the resisting face of the foil causes the foil to pivot freely within the framing device, thus transferring the resulting oscillation to the lure for the purpose of attracting and catching fish.
