One of the best things I saw at the Rigging for Big Gamefish seminar was the pair of pliers they used for rigging. The Manley Super Pliers (5") are well built and have a very nice wire cutter along the outside edge. The jaws are wide and are outstanding for crimping down barbs. The jaws have a groove that serve as a nest for the hook keeping it centered in jaws for an even crimp.
I ordered mine online for $35 with a synthetic sheath. Worth every penny!
