Sometimes bad things happen to good fishermen. You make a long cast with a shock leader, say, and the knot catches, pulling the ceramic ring out of the tiptop of the rod. Now what? You've got to reel in the lure, cut the line to remove the ring (being careful not to drop it in the water) and use your fishing pliers to gently squeeze the ring back into the frame on the tiptop. Not fun. If you're prepared, however, minor incidents like this won't ruin your day on the water.
