Fishing Highlight of the Week: Many anglers replace the hooks on their crankbaits with premium hooks to enhance their bite when a fish strikes. A pair of split-ring pliers is a must-have for anglers tackling this chore. Insert the tooth at the tip of the pliers into the space between the wire coils of the split ring. As you squeeze the pliers, the split ring will open, allowing you to slide off the old hooks and slide on new ones. Swapping trebles without the pliers is possible, but is much more time consuming, and your chances of sticking yourself with the hook increase.
