The Luhr Jensen Herring Aid comes with a leader with a trebble hook and a bait head. The whole bait or cut bait strip is inserted into the bait head, then a toothpick is inserted thru the bait holder to secure the bait. Tuning of the bait is accomplished by inserting the hook in the bait and placing a slight bend in the bait.
