The Butterfly Knife is a melee weapon and is just like a knife (only the butterfly knife is shorter). It appears in Grand Theft Auto: Vice City Stories and doesn't make much more damage than a Baseball Bat. It can be bought at Stonewall J's. On the radio station V-Rock, Cousin Ed claims that the Butterfly Knife is "the pinnacle of reckless living."
