Named after one of the most valuable officers in the Roman Legions, the Optio tactical is designed to perform as a tool as well as a weapon. There is not much to look at as far as aesthetics on this knife, just pure functionality. With a total length of 7 1/2 inches (without the sting), it makes for a great edc knife, made out of dependable DC53 steel that also provides excellent strength and toughness. DC53 is an improvement over alloy tool steel D-2, with an almost 3 1/2-inch cutting edge. 5 mil thick makes it an extremely sturdy blade. The handles are made with tough grooved G10, and they're perfectly agronomical with a finger guard incorporated into the design. The sting provides you with an extra tool or weapon, if necessary. The kydex sheath attaches to your belt with a Tek-Lock attachment that can be repositioned to be carried horizontally as well. It also works perfectly on any tactical pack or plate. We offer a written lifetime warranty on this knife; if you look after it, the Optio will look after you for a lifetime and some more. Available in coyote brown and forest green.
