The BladeLight folding knife from SOG Knife & Tool features a patent pending technology that employs 6 LEDs molded into the GRN handle on either side of the knife blade, providing shadow-less light when cutting or flashlight capability (while sheathed or closed). Of course the knife can still be used without turning on the LEDs. Powered by standard AAA alkaline batteries, state of the art push button switches/circuitry and an IPX-7 rating for water resistance to full immersion its easy to see the BladeLight is no amateur. Twin AAA batteries provide 34-37 Lumens of bright white light.
