The Trokar HD Worm Hook features Trokar's signature surgically sharpened three-sided hook point which makes this the sharpest worm hook on the market. These hooks are able to penetrate twice as easily as other worm hooks! Giving you a distinct advantage on the water. In addition, Trokar has beefed up the wire diameter of the hook, which aids in holding the fish after hook penetration. With easier hooksetting and better holding there is no reason to not use the TK100 Worm Hook!
