One man’s safety precaution is another man’s deadly weapon. Sure, the TAD Gear Titanium Rescue Ring is meant to break glass in case of emergency, but come on, it’s a ring with a spike on it. That’s bad ass. It includes a keyring for the breaker tip in case you don’t want to always wear the spiked ring… although we don’t know why you wouldn’t want to. Frankly, we intend to get one for every finger.
