Have you ever wanted to see a criminal piss himself? If he confronts you when you have this knife, he would.
That is unless he sees a 7" inch long stiff object printing through your pants. In that case he would probally run away screaming like a scared little girl. He would be scarred for life
(He would never again feel like a real man).
This knife could also come in handy when courting the ladys. (They would assume that you were always happy to see them.)
