With the Aura line, SOG built on the traditional ideas of the past and evolved them for the future. SOG thought about weight, ease of carry, safety and intuitiveness. SOG studied the original bowie knife created by Rezin Bowie in 1838. They considered utility, ergonomics and comfort. The result... the Aura fixed blade. SOG used a high impact and tough glass-reinforced polymer handle that is overmolded with a more pliable material for non-slip comfort. They didn't want a big clunky crossguard that isolated the hand so we adapted the blade design to provide the element of safety and allows greater control. And just in case your extremely sharp and durable edge requires a touch up in the field, unscrew the carbide sharpener in the back of the handle and reflect that yes, maybe this is a new day in knives. Check out the Aura in multiple fixed and folding blade configurations.
