The lure fishing targets are all the ferocious fish that predator from live and crustaceans.Of course the fight is intense, so the split ring must be tough enough to withstand the pull of fish.
However, if you pursue the toughness, the wire will become thicker and the split ring will become thicker and bigger, which will inhibit the action of the lure.As a result, we have created a special metal material or special processing during manufacturing, while minimizing the size of the split ring but not to lose its strength.It is exactly the right design for lure fishing.
