Kootek K1 Survival Flashlight

Most flashlights have long tubes filled with batteries. You might expect the water resistant Kootek K1 Survival Flashlight, measuring at just a touch over 12-inches, to have batteries for days, but it’s instead hiding a 3.5-inch serrated survival knife on the back that you can bust out in an emergency or for self defense. It’s also got a window breaker and of course a flashlight, the latter based on a Cree T6 LED that outputs a blinding 800 lumens and cycles through several brightness and strobe settings. And if you don’t need the knife just remove the furthest segment and attach the window breaker straight to the flashlight module, creating a more compact (6.5-inch long) torch.
