Tom Morello's Allen Wrench Scratching

From Guitar World (i believe)
In the song "People of the Sun", Tom Morello puts a new spin on an old trick. He plays heavy slide guitar in the tune to create droning single note riffs. However, instead of a usual brass or silver slide, he uses an allen wrench. This creates a dissonant, scratchy tone. Try it with heavy distortion to get the desired tone.
