  • Patent number: 3942280
    Abstract: An embodiment of fish lure comprising a body which may be made up of articulated components, has a cross-section which includes a central web and flange portions, such that the fish lure is relatively lightweight, yet appears as a full-bodied fish conforming to the shape of a small bait fish upon which larger game fish feed. The fish lure may be provided with an adjustable diving plane at the head portion thereof and has a thin web and flange cross-section throughout the body portion to be pulled through the water with ease. The fish lure construction is ideally suited for use to attract large fish and can be broken down for storage.
