Small and light, sharp (stainless knife with spear point), loud (two-chamber whistle), loud again (survival orange color), bright (it's got an LED light for those evening trips to the loo). All in all, it's an amazing little survival kit in less than a couple of ounces. And it's got a belt clip, so clip it on your blue jeans pocket for those day-to-day emergencies, like opening Christmas boxes and killing bears. No, don't kill the bears.
