The use of O-rings offers significant advantages in terms of durability and cost savings, as the hook no longer pierces the soft rubber lure directly, preventing the material from tearing easily. Instead, the hook is slid under the elastic ring, ensuring the lure remains securely fixed even during long casts, fish attacks, or fishing in snag-filled waters, and allowing it to be used for considerably longer. This saves money, as significantly fewer replacement lures are needed per fishing day.
