BladeLight. It's patent pending technology employs 6 LEDs molded into the GRN handle on either side of the knife blade, providing shadowless light when cutting or flashlight capability (while sheathed or closed). Of course the knives can still be used without turning on the LEDs. Powered by standard alkaline batteries, state of the art push button switches/circuitry and an IPX-7 rating for water resistance to full immersion it's easy to see the BladeLight is no amateur. When night is upon you, no longer will you be juggling a light in one hand and knife in the other. The clip point blade folds into a sleek molded GRN handle with liner lock. Twin AAA batteries provide 34-37 Lumens of bright white light.
