The Lazer Trokar HD Worm Hooks feature Trokar's unique surgically sharpened three-sided hook points - making them twice as sharp as any other hook on the market. Proven in tests to penetrate with half the pressure required for other leading hooks, the Lazer Trokar HD Worm Hooks benefit from Trokar's Surgically Sharpened Technology (SST). This patent-pending process precisely grinds the three sides of the hookpoint using a high-speed, computerized grinder designed for surgical needles. Lazer Trokar also determined the precise angle of the Low-Profile Barb using highly specific geometric calculations to provide easier penetration and the ultimate in holding power.
