An integral molded metal sinker has a streamlined body with a pair of wings and a keel fin projecting therefrom. The body has a bulbous, semi-spherical front end which tapers back smoothly to a relatively small rear end. A wire is embedded in the body and extends from the rear end to the front end thereof. Swivels are connected to opposite ends of the wire for attaching the sinker to a fishing line and to a leader. The rear swivel is near the central axis of the body, but the front swivel is substantially above the central axis of the body, thereby placing the center of gravity of the body substantially below the front swivel and tending to prevent rotation of the body. The leading edge portions of the wings are angled downwardly with respect to the rear portions to make the sinker tend to dive when it is drawn through the water. The downturned wing portions are substantially rectangular in shape to maximize their area for a given wing span and width.
