There is rarely an acceptable excuse to be unarmed. Some situations make it tougher to be armed, but that's where this discrete stabbing tool comes into play. I've seen gun-free zones, and I've seen knife-free zones, but I've never seen a pen-free zone. Technically, that's what this is, a pen. A pen with a secondary tungsten tip.... The Discrete Stabbing Tool is a low-profile and brutally effective tool for ensuring complete and total pain compliance. It's also just as capable of breaking glass as it is at kicking ass.
