Narrator: You are about to get a bird's-eye view of the difference between the one blade shave on your left and the two bladed TRAC II shave on your right. As both razors shave, the first blade lifts the whisker out from the face, but the TRAC II razor has a second blade that can shave the whisker again, closer before it all snaps back. Even with two strokes, no one blade razor can make that statement. And the TRAC II is safer because the blades are recessed. The Gillette TRAC II razor, the first razor with two blades.
