Start with a very clean and well-oiled grill. Place the steaks on the grill at about a 45-degree diagonal to the grate. Grill for about 4 minutes, then rotate the steaks a quarter turn (90 degrees) so the angle of the steaks on the grill is about 45 degrees in the other direction. This will create a diamond grill mark pattern. Flip the steaks and grill them steaks the same way, at a 45-degree angle to the grill bars, then after a few minutes, turn the steaks another quarter turn (90 degrees) so that the grill marks form the same diamond crosshatch pattern on the other side.
