Abstract: A fishing swivel, such as a barrel, snap or three-way swivel, is comprised of a plastic material that exhibits a high degree of transparency in water, density greater than that of water, and adequate rigidity to withstand appreciable deformation while loads are exerted. Materials such as Polyvinylidene Fluoride (PVDF) and Nylon 6 (Polyamide 6) copolymers with a refractive index less than 1.55, a luminous transmittance greater than 75%, a specific gravity greater than 1.0, an ultimate tensile strength greater than 1,000 psi, and a tensile elastic modulus greater than 10,000 psi are preferred.

Abstract: A fishing swivel, such as a barrel, snap or three-way swivel, is comprised of a plastic material that exhibits a high degree of transparency in water, density greater than that of water, an ultimate tensile strength sufficient for a small embodiment to withstand the loads exerted during fishing, and adequate rigidity to withstand appreciable deformation while loads are exerted. Materials such as Polyvinylidene Fluoride (PVDF) and Nylon 6 (Polyamide 6) copolymers with a refractive index less than 1.55, a luminous transmittance greater than 75%, a specific gravity greater than 1.0, an ultimate tensile strength greater than 1,000 psi, and a tensile elastic modulus greater than 10,000 psi are preferred.
