The BladeLight from SOG Knife & Tool features a patent pending technology that employs six intensely bright red LED lights (three on each side of the blade) that have a measured output of 37 lumens and are designed for use in conjunction with night optics needed by military or law enforcement specialists. The fixed blade - made of 8CR13MOV stainless steel - is anchored to a glass reinforced black nylon handle. Two AAA batteries will provide more than four hours of burntime for the LED lights.
