The info is taken from SOG catalog 2008 provided by onlysog.com: "Only 1,000 produced. This limited edition Trident comes with a deeply acid etched SOG pattern that brings a new fashion sensibility to cutlery. With dual colored TiNi coating, each becomes unique art. Numbered limited edition. The SOG Trident uses well-proven means of delivering a knife blade to the open position with S.A.T. Now using a patent pending Arc-Actuator, the Trident locks stronger and releases easier. There is also a built-in safety to lock the blade closed".
