The Owner Hyper Wire Split Ring absolutely cannot be straightened out. Originally designed for saltwater applications, these super split rings are finding more and more uses for freshwater anglers who put a lot of stress on their equipment. Use the Owner Hyper Wire Split Rings on big swimbaits for bass or for northerns, muskies, or macks. Instead of tying directly to the eye of any bait, more natural movement is allowed with the use of a split ring. Try these Owner Hyper Wire Split Rings whenever you are catching oversized fish.
