This Titanium Multifunction Carabiner has a Decent Flashlight Built-in

Clip this badass little accessory to your belt or keychain to be prepared for anything. First off, it’s an ultra-tough carabiner made from titanium, meaning it’s strong enough to hold your keys and tools anywhere you go. It’s also got a built-in LED flashlight capable of generating up to 360 lumens, with four lighting modes plus a strobe function that turns it into a useful self-defense tool (along with a bottom bezel that can be used as knuckle-dusters). It even serves as a bottle opener, is IPX5 waterproof rated, and impact-resistant up to 1.5 meters. Thanks to its built-in lithium battery, it’s easily charged and delivers surprisingly good battery life for such a compact device.
