First off I am personally very glad to hear stories of decent people saved by their forethought and preparation. We all hopem and pray the day never comes but when it does we owe it to ourselves and loved ones to act, legally and responsibly, to protect ourselves regardless of the type of threat. I used a Gerber Guardian one time in a nasty situation. Coming out of a convenience store, I notice a large fellow sitting on the hood of my car. After asking him to leave, and noticing his friends in the car next to mine, I went back in the store to get a security guard. He was unfortunately unwilling to help out, so I went back outside and the man approached me. He and his friends joked about having a Deliverance sort of evening with me, and he grabbed me by the jacket. Outnumbered, alone and in fear for the sanctity of my person, I drew the knife, cutting him once across the lips and backing away to my car. Problem solved, no further action needed.
