The SOG BladeLight Tactical Knife is a great knife to keep on you for any type of tactical operation you may find yourself in. The six intensely bright red LED lights (three on each side of the blade) have a measured output of 20 lumens and are designed for use in conjunction with night optics needed by military or law enforcement specialists. The fixed blade is made of 8CR13MOV stainless steel and is anchored to a glass reinforced black nylon handle. Two AAA batteries will provide more than four hours of runtime for the LED lights. A molded nylon is included along with a lifetime warranty.
