The Double-Duty® automatic is a Double-Action automatic that can function as a one handed opening locking-liner knife or be instantly fired in the automatic mode. The automatic firing mechanism is hidden under the handle and is activated by sliding the left side handle scale towards the back of the knife. Because there are no apparent buttons on the outside of the handle the fact that this is an automatic is known only to its owner. This makes the knife convenient to carry and use anywhere. The blade is 3.00 inches of CPM-S30V high-carbon super stainless steel for great edge retention and toughness. The liners, pocket clip and internal components are stainless steel. The handle is gun stock grade cocobolo wood. The knife is lightning fast, good looking and comfortable in the hand.
