Abstract: A fishhook device includes a standard fishhook having a barb, bend, shank and eye. At least one piece of wire can be attached at one end of the shank of the fishhook, preferably substantially adjacent to the eye. The wire is biased by at least one biasing bend to an extended position wherein the free end is distanced from the shank of the hook, and can be flexed to a position wherein the wire is adjacent and substantially parallel to the shank. A retaining ring is positioned around the wire and the shank to keep the wire in the flexed position, and is the point of attachment for the fishing line. A loop in the wire is preferably provided substantially adjacent to the attached end as a guide for the fishing line. Movement of the hook relative to the fishing line will cause the retaining ring to slide over the wire to release the wire to the extended position, such that swallowing of the hook by the fish will be substantially prevented.

A line attaching eye is attached to the upper side at one end and a hook is attached to the underside at the other end. The buoyant material in the construction of the lure body will cause the lure to surface when retrieval of the attached line is stopped. In one embodiment of the lure employing a bill-like projection forming a planing surface which causes the lure body to dive and which due to the light weight buoyant material will cause the lure to surface when retrieval of the fishing line is stopped.

Abstract: A safety sinker includes a sinker connected to a fish line through a sinker coupler, wherein the sinker coupler may be pulled, by means of a fish line, to disconnect the sinker from the fish line when the sinker is squeezed in between rocks or somethings during fishing. The sinker coupler includes a fork end having two semi-sphere members made thereon for connecting the sinker when they are squeezed to form into a spherical configuration and inserted into the inner chamber of the sinker. The two semi-sphere members may be squeezed to form into a spherical configuration again, by means of a pull force through the fish line, so as to slip away from the sinker and to disconnect the fish line from the sinker.

Abstract: A rig holder for fishing rigs and leadered fishing lines is a flat panel of rigid material with a rectangular outline. The holder has a series of notches uniformly spaced along each of its long edges and four pairs of notches spaced along each of the short edges. On the front face of the holder is a recess carrying two strips of one component of a hook and loop pile fastener material, which are associated with patches of the other component of the fastener. Rigs may be secured to the holder in various ways, primarily by winding around the holder through opposite slots and securing the hooks in place either on the fastener strips using the fastener patches or in notches along the edges of the holder.

Abstract: Magnetism is used to reduce the tendency of a fish hook to snag. A magnet may be attachted to a fishing rig, or part of the rig or a hook may be magnetized, so as to attract a movable hook to a relatively shielded position in contact with the rig where the hook is less likely to snag than when it hangs loosely or is free swinging, or magnetism may be used to hold a weed guard in a position where it shields a hook. The strike of a fish can pull the hook free from the magnet or weed guard and enable its point to penetrate the mouth of the fish.

Abstract: A fishing device known as a spreader for trolling a plurality of baited hooks from a single fishing line wherein the spreader is a planar device with sweep arms extending from the body of the planar device and vanes that cause it to rotate as it moves relative to the water, thereby causing at least two fishing lures attached to the sweep arms to move in a helical pattern simulating the motion of fish swimming together. The hydrodynamic design provides for smooth operation in the water and reduces the propensity for the fishing lures to become entangled.
