The Blade Light from SOG Knife & Tool features a patent pending technology that employs six intensely bright LED lights (three on each side of the blade). The lights have a measured output of 37 lumens, enough to help sharpen a stick for marshmallows, light up a late night cookstove or help illuminate the way to the outhouse. The fixed blade - made of 8CR13MOV stainless steel - is anchored to a glass reinforced nylon handle. Two AAA batteries will provide more than four hours of burntime for the LED lights. A sheath is included.
